A Study of Loetz Cut Glass Production

                                                                                             by Dr. K. M. Hasselbach

Introduction into Loetz cutting Glass History.

Very little is known about Loetz cut decorated glass production. In the current literature this aspect is nearly neglected, though it must have been a considerable part of the total production output. Julius Fahndt characterizes in the 1901 edition of his  'Glass Address Book' [Ricke,I. page 33] the Loetz facilities at Klostermuehle by 'two ovens, 23 pots, wood fireing using the Siemens system, cutting store with 36 work benches, own refinery, 3 painting stores with 30 painters, a total of 150 employes ...'. Herefrom it becomes clear, that there were more cutting (36) then painting (30) facilities. Of course, the cutting was needed e.g. for grinding down glass vessels to a specified size or to polish out the 'pontil', the part left over where the glass was attached to an iron rod, when working the top rim. There must have been larger excess valencies for cutting décors, but from this and earlier periods, nothing is yet known, in contrast to the many enameled items that survived. In the early 'Art Nouveau' period, see [Hass], there was very large competition in between the bohemian glass companies. Outstanding with respect to glass and intaglio cutting were Harrach at Neuwelt, Moser at Meierhoefen near Karlsbad, Meyr's Neffe at Adolf near Winterberg and the Schaffgotsche' Josephinen-Huette at Schreiberhau, not to mention Baccarat, France, Webb and Stevens&Williams at Stourbridge, Great Britain or St.Louis, Belgium. Each of these companies made their own, significant contributions to the most advanced cutting decoration of glass. Nothing comparable was ever seen from Loetz, though its contribution of hot shaped glass to 'Art Nouveau' was not reached by any of these competitors. One reason might have been, that Loetz concentrated on its sucessfull iridized glass mainly and used cutting only in a tradional bohemian decorating fashion, such that it is up to now assigned to other Bohemian companies and refineries like Muehlhaus, Eiselt or Oertel&Co. Another problem might have been the lack of highly qualified cutting masters. Max von Spaun complaines in a letter to the director of the 'Austrian Museum of Art and Industry', in which he acknowledges the outstanding delivery of some items, [Neuw,I. page 254] '... the engraver needs longer time. It is difficult, as there were no engravers trained, that have any idea at all of engraving a flower nor ...'.


One rare example of intaglio cut gilded décor is the M. Kirchner vase PN=II/4867 (1907) shown in 1.01-02. The artfull decoration might have been applied by some other bohemian refinery, too.


Methodology of Identification

 To assign cut glass to Loetz the following elements have been considered:

  1. Paper patterns
  2. Shape, homology and general characteristics
  3. Décor and ornamentation
  4. Colour and colour combinations
  5. Signatures and marks
  6. Co-production and commissions
  7. Quality and style
  8. Documented museum pieces
  9. Contemporary photos and articles

Of course, attributions based on limited information can never be as reliable as those included in the published collection of Loetz paper patterns [Ricke,II] and [Lnen,II]. Therefore items identified by their PNs are the preferred reference in this monograph. But In these paper patterns cutting is usually not mentioned at all, only few exceptions are known. And in addition, many paper patterns of the late Series III were lost. Though, looking for shape similarity to known 'Production Numbers' (PN's), there remains still some possibility of misattribution.

Early Loetz cut glass

Up to now nothing is known about 'Early Loetz' cut glass in the last quater of the 19.th century. In a first attempt [Hass] assigned vase 0.01 based on its similarity to other 'Early Loetz' productions. For details please read my article 'An attempt to assign Early Loetz production from 1880-1897' on this web site. The vases 0.01-0.05 have same shape and the light blue and light green vases are both décorated by the famous 'Russian' cutting pattern, firstly patented in the USA in 1882 by Phillip McDonald when working with Hawkes and lateron widely used by many other companies. It is rarely found, that besides the fine cutting an enamelling of rich 'Rococo Revival' sccrollworks is applied throughout. On a first sight, these vases might be assigned to Moser, too. But as Moser started his own glass production not before 1895, up to then he used blanks from various other bohemian companies for refinement. As Loetz employed more cutters than painters, it is close at hands -besides many other reasons - to assume that Loetz décorated these vases itself.

In the pink vase the cutting opens a window in the stem and décorates the bulbous body. The simply eight sided ruby cut stem vase ornamented by Rococo scrollworks is signed Dek=44/86.

Loetz cut glass at the World Exhibition Paris 1900

At the 1900 World Exhibition in Paris Max von Spaun presented the most advanced vases in the newly developed 'Phenomen Genre' décor, designed by Franz Hofstoetter, winning a 'Grand Prix' and thereby laying the foundation for the future successfull expansion of the Loetz art glass production.

1.03                                  1.04                                         1.05




Whereas in 1.03 PN=II/379 (1900) and 1.06 PN=7465 (1898) the threedimensional appearence of the leafes seems to be accentuated by cutting only, the flowers of 1.04 PN=II/406 and especially the deeply cut ornament of 1.05 PN=II/380 form an integral part of the décor. 1.03,1.05 and 1.06 are scanned from [Ricke,I.124.94,125.95,115.78] and 1.04 from [Mergl,101.46]. In the following years Loetz concentrated on hot schaped glass and explored more and more complex irisation patterns, cut ornaments were not futher applied nor developped.

Cut Vases known from Paper Patterns.

The relevance of the paper patterns (PNs) is extensively discussed in [Ricke,I.;Hass].These published paper patterns [Ricke,II] and [Lnen,II] are the primary source for identifying Loetz glass. Sadly, for the period 1885-1936 only 11 paper patterns out of the survived 7171 PNs, put together in 2.01-02 from [Ricke,II], have cutting specifications. One paper pattern with PN=III/4986-99 (1930), showing also two sketches of cut parfume bottles, is not included here.


The appearence of the 12 vases of Series III (1914-24) made acording to these paper patterns - either in 'Kristall, Saphir, Amethyst or Topas, hohl geschaelt' - must have been very similar to the well known hollow/panel face cutted vases of Moser or from Josephinen-Huette and might still wrongly be assigned to one of them.

2.022.02 2.02 A2.02 A

In [Ricke,II. page 589] there are four and in [Lnen,I] there is another advertizing Loetz sheets of paper patterns published, these are photographed directly from the book by the author and presented here, too. The 1.st two show Ausf-276 (1927) 'Kristall mit verschiedenfarbigen Luestern und matten Blumenschliff 333', here in 2.03 and in the following the shapes are referenced by their PN's (1912-27) below each vase.



2.03 A2.03 A



2.04 shows a earlier cutting décor of ~1920 with shapes (1912-1923) and 2.05 a 'Schliff 367' from 1927 on one shape of various sizes. This vase is shown again in 3.05.



Finally in 2.06 the 'Schliff 249' applied onto a toilett garniture is given. The bottom star is always explicitly drawn. From the documented 'Schliff numbers' it is obvious, that there must have been a cutting reference book at Loetz (similar to the paper patterns) containing sketches of the uniquely numbered cutting décors - the largest décor number currently known is 367 - and this book seems to be lost.

From the 'Loetz Musterschnitte' collected in [Ricke,II] only 20 shapes are documented for the years 1930-1936, the PN's ranging from 5122-6529. This reveals the large number of still unknown shapes in the late Loetz production period.

In the collection of the Loetz design papers in [Lnen,II] there are a number of PN's where cutting is explicitly mentioned, these are put together in 2.07-2.15.



2.07                                                                                         2.08


2.09                                                                                         2.10

In 2.07-2.11 a toilett garnitur PN=II/5528 (1908) décorated by either 'Schliff 5' consisting out of a varying number of roses  or 'Schliff 6' fans with enclosed lattice by large crossed miters. These are the earliest 'Schliff' numbers known. It seems, that Loetz used from 1908 onwards a systematic, possible new, cutting enumeration. The known ducumentaion ends with 'Schliff 367' in 1927.


2.11                                                                          2.12


2.13                                                                                                          2.14

The bowl 2.13 PN=II/8653 (1913) shows a simple cutting, made of olives, similarly as the one shown in 5.01. Loetz décorated lamps and shades by cutting, too, examples are 2.12 PN=II/8408 (1912), 2.14 PN=II/8779 (1914) and 2.15 PN=II/8789 (1914).



Then there are some PN's mentioning cuttings without showing explicitly the design of the cut. 'Schliff 8' is applied to PN=II/7756/4" (1911), 'Schliff 47' to PN=II/7755 (1911) and 'Schliff 59' to PN=II/7761 as well as to PN=II/8652 (1913).

Putting the documented cuttings together, explicitly known are only 7 cutting designs namely 'Schliff 5, 6, 30, 59, 249, 333 and 367, a very small number, out of the - at least 367 cuttings - applied by Loetz.


Examples of Loetz cut glass.

After the very successful 'Art Nouveau' period, dominated by iridized glass, Loetz looked ~1904 for other methods of decoration and introduced new glass types like 'Ophir, Titania' or 'Tango' glass besides many others. In the 'Laurus' décor, the red apples are shaped by cut bul-eyes, that were coloured red. One example is shown in 3.00 PN=II/1449 (1904), others may be visited under the 'Décor Index' on this web-site.


Especially Adolf Beckert, who became in 1909 director of Loetz, forced orientation into a new direction of decoration by establishing fluoric acid etched decoration. His designs are outstanding examples for this newly introduced production, much simpler is e.g. the neo-classical 'Etrusk' series. For the market Loetz established ~1920 a mass production of etched vases 'À Gallé' sold under various names like 'Richard, Veles, Lucidus, S.Pumoulid, S.Ramillay, C.Huilay' [Lnen.I, page 63] as well as under its own name 'Ca Loetz' or just 'Loetz'. The important aspect here is, that Loetz combined cut and etched decors together on one item, many examples of which will be shown in the following. About 1925 the largest part of the Loetz production consisted out of coloured-cut-to-clear overlayglass, produced mainly for export. As there was not enough capacity for cutting available at Klostermuehle, Loetz established in 1925 another cutting place at Unterreichenstein together with Jos. Schuster&Co [Lnen, page 60] to satisfy the demand for traditionally bohemian cut glass and marked it mainly to Europe under 'Cristallerie de Turn'. This company decorated Loetz blancs up to the beginning 1930's. The basic colours included ruby, blue, amethyst and amber overlayed blancs, typically having a thickness at the rim of about 5-6 mm increasing to the bottom to 10 mm, allowing for deeper décor cutting. The following 5 examples of this period, taken by photographs from the excellent book of W. Neuwirth [Neuw,I] are shown in 3.01-05. Analyzing carefully the cutting pattern of 3.01 one may detect an interesting Loetz specific feature: The deep miters of one part of the décor - here a star - are crossed by miters of another part - here a diagonal cross, or a vertical fence - and in the following I will refer to this feature as 'Loetz crossing miters'.



The décor of 3.01 is similar to 'cut 241' in 2.06 and the shape of vase 3.05 matches 2.05. The bottom of each vase is decorated by a cut star or by more complex patterns with hobstars and fans separated by miters.

Loetz cut glass presented at the 'Werkbund' exhibition at Vienna, 1914.

Contemporary articles illustrated by photos are of great value on identifying and assigning Loetz glass. There exist some photos at the Loetz archive showing cut glass presented at the 'Werkbund' exhibition at Vienna, 1914. The vase 4.01, also shown in [Ricke,I.page 278.338], is a rare example of a cut vase designed by Dagobert Peche, and the rather diffuse photo 4.02 from [Ricke.I, page 267] displays a excellent drinking set, possibly designed by Josef Hoffman.


The vase 4.03 is also taken from [Ricke,I. page 269.322], it was designed by Josef Hoffmann PN=II/5220 (1907), it combines etched square surfaces with cut bull-eyes. These three contributions demonstrate clearly, that Loetz could easily compete in the high end 'Art Déco' cut glass with other Bohemian refineries as Oertel&Co, Carl Schappel or Carl Meltzer&Co. Two fine vases, designed by Hans Bolek are shown in 4.04 PN= II/259 (1913) crystal with dark blue and cut arches, comissioned by the 'Austrian Werkbund' and in 4.05 the foot shows cutting, too.




Early iridized and cut glass.

Besides the pieces shown at the Paris 1900 World Exhibition only few examples are known, where Loetz combined iridized glass with a cut décor as in 5.01.

The PN=II/8209 (1912) taken from [Lnen,II] is shown in 5.02 and describes the vase as 'Cristall Goldiris' - having an iridized 'Candia' overlay over crystal clear glass - and the applied cutting as 'Schliff No 30'. The low number of this cutting No 30 suggests, that Loetz started systematically numbering cutting décors rather late, or possibly used a different numbering system before 1912, or - what seems reasonable - did nearly no cutting at all before 1912.



An exception is the very early vase 5.03 carrying the first phenomen décor Gre-166 PN=I/7474 (1898), where the feathers are accentuated by cut outlines similar to 1.03 and 1.06. Another example with a cut décor on Gre-6893 (1898) is shown in 5.04, a vase obviously produced to fit into a montur, as there is no pontil and the top rim is polished. Wether the cutting was originally applied by Loetz, or much later, to hide damages due to the ormolu, remains unclear.


Cutting combined with etched glass

As already stated above, Loetz widely used etched décors in combination with cutting. In contrast to the examples in 3, these vase are made out of relatively thin overlay glass, typically the glass of a vase measures at the top rim 2.5-3.5 mm increasing up to 5 mm to the bottom. The cutting therefore consisted of flat curved miter, panels and bull-eyes. There are 8 examples exhibited at the Passau Glass Museum (PGM) and they are shown in 6.01-03. All vases show an etched band of either wild roses, oak leafes or fruits and cut panels above and/or below it. Vase 6.05 PN=III/2411 (1925) in 2.03 and in the background of 6.01 shows the details more clearly.



The two vases in front of 6.01 nearly match PN=III/3637 (1927) of 2.02 and the vase in the background of 6.03 has a shape seen often with differing décors as in 7.01, 10.01 and 11.01.

The collection of vases 6.04 are exhibited in the Museum Sumavy, Kaperske Hory, Czech Republic. The upper middle and the vase on the lower part at the right side are made in a similar style like 6.01-03.


But one must bear in mind, that Kralik produced quite similar vases and care has to be taken, not to use 6.04 uncritically. From the known 31 Kralik paper patterns 6.06, one must conclude, that in the top row of 6.04 the 3.rd vase left actually is Kralik PN=6037, the large vase 3.rd from right is PN=5676/1, and in the bottom row the 2.nd and 3.rd from the right side are Kralik décors PN=5342/5 and 5322/4 too.


The vase 7.01 matches the shape already seen in 6.03, but here the red outer layer covers a light 'Anna' green uranium glass as is seen in the 'Loetz' signed vase 7.02, too. The vase 7.01A PN=III/978 (1919) and bowl 7.02A PN=III/2410 (1925) repeats the décor of 7.01 on clear glass. A 7.027.02


7.02 A7.02 A 


For comparison purpose the purely ruby-red-cut-to-clear Kralik vase 7.03 PN=5322/4 in 6.06, it matches the shape as well as the cut/etched décor of the 3.rd left vase -executed in blue over crystal - in the bottom row of the showcase in 6.04. The etched motiv reminds onto décors designed by the 'Glasfachschule Haida'.

The vase 7.04-05 shows an ruby red etched vine foliage décor on additionally cut uranium glass. The characteristic triangle feature is met again in 8.








In 7.06-07 again the décor seen in 7.01-04 is shown onstill another shape.


7.06                                                                        7.07

 Two examples of vases with combined cut and etched décor of fruits are presented in 7.08-09.



The vases 8.01-06, 9.01-03 and 10.01 exhibit all the same geometrically etched décor of dark blue, ruby red or light green glass on crystall, respectively. Small triangles or squares are cut out and polished. 8.01 and 10.01 are PN=III/1146 (1920) and 8.02 is PN=III/8441, the shape indicated in 2.06 left 2.nd lowest row vase. The two vases 8.04-05 resemble the shape of 8.02, but without bottom foot.

 8.06 and 8.07 repeat the décor 8.01-04 onto another shape.


8.06                                                        8.07

Here I would like to recomend reading the excellent article 'Loetz Cameo and Acid Cutback Decoration' by Warren R. Galle, Jr., also published on this web-site, where some of these vases were discussed in another context, too.



















The décor of 8.03 is repeated again in 9.03 in dark blue over light brown and a quite 'Modern' cut pattern is seen on the same shape in 9.04. It is signed by the acid etched merged capital letters OL for Oswald Lippert who made designs for Fachschule Steinschoenau and executed some himselves ~1930, here puplished the first time that he used Loetz blanks. Both vases match the shape of 7.01 PN=III/978 (1918-19). 

The Oswald Lippert décor is repeated on 9.06 PN=II/8127 (J.Hoffmann) , a vase of same colouring as seen in 10.02 and 9.07 shows another cutting on a dark-blue over 'Topas' grounded vase.


10.0110.01 9.06                               9.07

In 9.08 the 'Topas' dark-blue colour combination with the decor known from 8.01-03, 9.03 is seen again.




The vase 10.01 has again the same shape as 6.03, 8.01, 11.01 and the décor is cut and etched from the dark blue case 'Annagelb' ground.

In 11.01 the petales of a tulip are accentuated by cutting out the inner part of the blue etched flowers, the décor is much better seen in the wonderful bowl 11.02, the shape nearly matching 3.04 or the bowl on the upper board of 6.04.



Similarly made is 11.03 showing a ruby basket with 'lily of the valley' flowers. 11.04 has same décors as 11.01-02 on shape of 11.03 PN=III/512 (1914). 




Vase 11.05 repeats the décor of 11.01-02,11.04 on a ruby red over 'Annagelb' footed vase PN=III/3066 as can be seen in 2.03.



A completely different dècor is etched and cut on 11.06, PN=III/346 as listed in the design sheet 2.03.


In 12 the vases and the bowl follow the flower theme of 11.01 but show a cut thistle. 12.02 is an detail enlargement of 12.01 that gives a good impression of the etched part and structured background, as well as of the bevel cut and polished petales, the leaves of the flower and the bull-eyes around the top rim. The PN~III/164 (1906) [Ricke,I, page 586].

12.0112.01 12.0212.02


12.04 shows the same motiv on a shallow bowl and 12.05 on the shape known from 7.02A.


This thistle motiv is shown on 12.06-08, too. The shape of 12.06 PN=III/512 (1914) is the same as in 11.03-04.


12.06                                                           12.07




Loetz vases décorated by cut rims only

Vase 13.01 is covered by dark blue etched flowers - known from Loetz vases signed 'Richard' - and only both rims are decorated by cutted  parts.


Similarly in the vase 13.02 designed by Hans Bolek PN=III/1054 (1920) the main décor is etched as well as the 'Loetz' signature and only the top rim is shaped by cutting.



Some examples of purely cut decorated vases.

Similarly shaped bowls as 13.01, but standing on three clear glass spheres and the body decorated by cutting only are seen in 14.01-02 PN~III/918 (1918). 14.01 has an interestingly decorated top rim seen again in 19.01-02 and 20.03. The second bowl is decorated by a cut frieze of crystal clear lily of the valley with light green leafes, contrasting to the dark blue sky PN=III/616 (1915) see [Ricke,I page 586].


Of similar shape PN=III/918 (1919) are the two bowls 14.03-04, the simple cutting repeats the threefold symetry defined by the three applied spherical feet.


The vase 15.01 PN=II/8030 (1911) designed by Josef Hoffmann has 'Thea' yellow flowers and ornaments on a black contrasting foreground and is displayed at the PGM, too.


Sky-blue-cut-to-'Thea' is the vase 16.01 PN=III/1119 (1920). The décor made of thumb-prints only, harmonizes with the three sphere stand. The colour combination of blue/yellow is quite often found in Loetz cut items.

'Blumenschliff 333'

Three examples of the 'Blumenschliff 333' (1927) see pattern 2.03 in dark blue over crystal - with an enlargement of the cut rose - are presented in 17.01-09, as they are not enclosed in 2.03 and have no 'Luester' irisation, nor the top rim decoration as sketched in 2.03, they are different from the Ausf-276 execution mentioned in the advertzing sheet and discussed below.







The small vase 17.07 with PN=II/8655 referenced in 2.03 resembles 17.03, but cut to clear from a ruby red flashed glass.

The bowl 17.08 repeats the shape of 7.02A and the 'Blumenschnitt' is executed on dark green over topas glass, another example of the variety of Loetz colour combinations. The vivid emerald green vases 17.09 and 17.09A  are decorated by the simplified 'Blumenschnitt' known from 17.04 and do not have the thumbprints arround the mouth as compared to 17.04-08. Other examples of vases with 'Blumenschnitt' are continued in 44.






Loetz Ausf-276 is only known from 2.02 and 2.02A, it is not mentioned in [Ricke,II] nor [Lnen,II], the décor consists out of 'Blumenschliff 333' applied to clear glass and coloured by irisation, in contrast to 17.01-09 where the 'Schliff 333' is applied to clear glass coloured by an outer layer of glass. The vases 17.10 with shape PN=III/355 and 17.11 PN=III/2209 show both a purple irisation, they both have the same rim décorations, also a part of the décor Ausf-276.


Three carafes PN=III/4602 in iridized pink, blue and purple Ausf-276 are grouped together in 17.12-14.


17.12                                                          17.13



'Schliff 249' and related items

18.01 illustrates a more deeply cut décor like the examples in 3, the shape of the tall vase is similar to PN=II/8125 (1912) by Josef Hoffmann. As this type of cutting was widely used by many Bohemian refineries, the vase could have been

decorated by other producers as well.


The similarly shaped vase 18.02-03 PN=II/2272/343 is décorated by 'Schliff 249' as shown in the paper patterns 2.06. All vases in 18 are made of thick glass coloured by an outer layer and decorated by deeply cut patterns.


                             18.02                                                            18.03

18.03 shows a related vase of same shape with a cut bird sitting on a branch and 18.04 resembles this popular shape décorated by a geometrically cut to clear layer of cobalt blue glass surface.

18.0418.0418.04 A18.04 A18.0518.05


The central yellow parfume bottle of 18.05 matches PN=1385/5 of the toilett garnitur in 2.06 showing examples of 'Schliff 249'. The two red bowls are cut similarly and show the characteritic 'Loetz cutting miters' of a 3.06. The intricate cuttingt of plate 18.06 fitts to the red bowls in 18.05 accordingly. Another variant of Schliff 249 my be seen in 21.03. 





The bowl 18.07 with a fine ormulu of two dragonflies resting at the top rim resembles partly the cutting already seen in 18.




A Floral cutting Décor

In 19.01 we meet again another often cut décor, here in ruby red glass on the well known shape of 8.01 and 12.03 PN=III/1146 (1920). The same cutting is applied to 20.01-02 PN~III/787 in 2.03 or III/858 (1916) of Michael Powolny, a crystal vase having an outer dark blue and an inner yellow case as well as a yellow stem, a colour combination known from 16.01 and seen again in 21.01-02, 22.01 and similarly in 24-26.



















The cutting of the top and arround the foot - clearly seen in 20.02 - a characteristique Loetz pattern, was applied to 14.01 and 19.01, too.


The same cut ruby-red cut to clear is applied to the three footed vase 20.03, the shape already known from 14.01-02.


The already known décor 20.01-03 is applied to 20.04 and to 20.05 combined with strawberies as in 19.01, 20.02.


20.04                                                            20.05

Two ruby-red bowls footed on ball feet cut to clear are shown in 20.06 and cut to 'Annagelb' in 20.07.


Some other cutting décors

The dark blue/yellow colour combination over crystal clear is used in 21.01-02 and 22.01. The applied cutting and intaglio of the tiny flowers remember onto 1. The cutting of the tall vase 21.02 nearly matches 'Schliff 6' refrenced in 2.07-2.11.




The three vases 22.01-02 and 23.01 share the same shape and cutting, but the latter is made of red over orange glass and both exhibit a cut bottom star.


22.01                               22.02


In the series 24.01-26.02 the dark blue outer case appears nearly black and the inner case is made of 'Mandarin yellow' spreading glass. The shape of 24.01 is similar to PN=II/8122-8123 (1912) by Josef Hoffmann, its combination of strongly iridized blue over 'Topas' is similarly seen in 40. The cutting of 25.01 nearly repeats the décor of 14.01.


26.01 is exquisitely dark-blue cut to 'Topas' into thicker glass, it has a bottom star and the details of the rose itaglio cutting in 26.02 are the same as in 18.01.The PNs of the vases 21-26 are not yet identified, due to the many paper paterns missing in the time of WW I and the following decades, therefore their assignment is still under debate.


At this time Loetz made its own colour glass cones, therefrom the colouring of the produced vases are very specific and many different colour combinations were produced and blancs were traded to many bohemian refineries as Carl Hosch, Tschernich&Co, Karel Palda, Fachschule Steinschoenau and many others. In 27-28 the blue/'Camelien red' combination is presented. The shape of 27.01 is clearly seen as the outermost right vase in 6.03. The vase 28.01 nearly matches PN=III/2225 (1925) similar to III/849 central right vase in the lowest row of 2.04.



The shape of the light green vase 29.01 remembers onto the Powolny designed series III/840-858 (1917), the geometric square décoration onto examples 8-10 and the top and bottom rim décor is known from 17.10 Ausf-276 and 44, 45.

Three colours were applied in the Loetz 'Rainbow' vase PN=III/3611-3628 (1927) and this colour combination with an outer case of dark blue was used in combination of cutting by Loetz, too. A bowl exhibiting this rare combination with a cut similar to 'Schliff 249', documented in 2.06 and already seen in 21.03, and with applied bottom star is 30.01.




In 30.02 the same 'Rainbow' colour combination is seen again. Though Stevens&Williams, GB made similar glass, but usually by applying a much more elaborate and characteristic cutting and itaglio décoration, these two examples  with their traditional Bohemian cutting shown here, are assigned to Loetz. Another 'rainbow' vase decorated by massive diamond cutting with terminal fans is 30.03, the shape of which is similar to some Loetz 'Cobalt Papilon' vases made during the 'Art Deco' period.


In 31.01 a finely cut/engraved vase of thin glass, nearly perfectly matching PN=III/929 (1918) of M. Powolny is presented, but as Powolny's shapes were very popular and have often been copied, this vase might have been produced by some other Bohemian company as well.



Panel face cutted vases

The intensively red, face cutted vase 32.01, of shape PN=III/4664 (1928) referenced in 2.02, is one example of this popular style, used by Moser, Josephinen Huette and many other Bohemian companies, too. The green vase 32.02 is made according to PN=III/533 (1914) - the mouth widened - applying a 12-fold face cut as in 32.01-03. 32.04 is made in the same red colour as 32.01.


The 'Amethyst' and the yellow coloured vases are sketched in 2.02 as PN=III/2085 (1923), the only difference being the face cutting is running in three steps from top to bottom as compared to the separated two parts in the paper pattern.



The panel face cut vases shown here are examples assigned to Loetz, though there is still some possibility, that some might have been made by other producers as Moser, Josephinenhuette or Riedel.


Some geometric Décors

In contrast to the face cutting applied to thick walled glass, the cutting décoration of thinner glass needs a different technique. You may have a look onto the central triangle of 8.03 composed out of three flat cuttings each of a half-moon shape with a deeper edge at the straight side. This intaglio cut décor is applied to 8, 9 and 10.02, not only forming triangles but trapezoid shapes, too. This characteristic Loetz cutting feature is used to shape the rose-flowers in 17 and is also seen in different combinations in 33.

33.0133.01The shape of bowl 33.01 is noticed in [Ricke,II page 379] as PN=Com 572/1 (1912) and made in many different colour combinations for the 'Fachschule Steinschoenau', the ruby-red cut to clear bowl was probabely decorated by Loetz themselves. The vases 33.02-04 are cut similarly, 33.02 follows PN~III/2084 (1924), the PN of the blue bowl 33.03 remains unknown and 33.04 is a taller, blue variant of 33.01. In the past these vases were most often assigned to Fachschule Haida or Oertel.



33.05 is cut using the same characteritics, the shape is similar to PN=III/804 and III/904 (1917). The cutting of lidded bowl 33.06 is similar to the top rim of 33.04.



The vase 34.01, with its simple cut, was designed by Josef Hoffmann PN=II/721 (1915) and its shape is in the spirit of 7.02A and 17.08. As Johann Oertel and Wenzel Kulka both used Loetz blanks, the cutting is sometimes assigned to one of them. The vases 34.02-05 are made in the same spirit and are similarly décorated




In 35.01 a vase décorated by a dynamically cut flower motive, not known from any early publication, of PN=III/3499 (1927) with remark 'Dark blue over Cristal for cutting, very urgent', this is another hint on cut glass noticed in the collection of the 'Musterschnitte' [Ricke,II]. The similar dynamic motive in 35.02, the leaves are cut like those in 45, make an assignment to Loetz quite plausible.  



Two vases 36.01-02 of matching shape PN=III/2085 (1920), see 2.02, the blue one, cut in the spirit of 33 and the ruby red vase in a manner similarly to pieces often assigned to Joh. Oertel&Co, Haida.


The diamond cut vase 37.01 is made very much like 7.06 but missing the central 'Blumenschliff'.




Newly identified Décors

The vase 38.01 with shape PN=III/355 (1914) shows a variant of 'Schliff 249', documented in 2.06 and similarly applied to the rainbow vase 30.01, here on a combination of 'Anna'-yellow/dark blue glass. The cutting consists out of crossed meters, topped by fans and hobstars in the centers and show the characteritic 'Loetz cutting miters' of 3.06. The rim décoration is similar to 14.01-02 and 19.01, 20.01 and 35.01. The bowl ruby red over clear 38.02 shows the same cutting.


38.01                                               38.02

The vase 39.01 shows a floral cutting from a ruby red overlay over uranium glass like the etched examples in 7. A quite similar décor is etched in the iridized vase 39.02 PN=III/8412 (1912).


39.01                                                                                            39.02

The dark blue over clear crystal vase 40.01-02 shows a new cutting similar to 18, 'Schliff 249' and 38 on the typical shape PN=III/8441/8" as sketched in 2.03-04. Interestingly the Rococo scrolworks gilded ruby-red cut to clear vase 40.03 exhibits the almost same cutting design as seen in 40.02.


40.01                                                                                      40.02

loetz cut 40.0340.03

In the same shape as 40.01-02 comes the partly cut with - etched motiv of dancing couples - vase 41.01.


The colour combination of dark blue over 'Topas' yellow was introduced in 9.03-07 und is used again on the pair 42.01 combining etched and cut décors on the well known shape of 17, 40 and 41.


The same type of décor is applied in ruby-red cut to 'Topas' with a different ornament. Both vases 42.01-02 show a high iridescense over a matte treated background.


Another newly assigned dècor of wine foliage with grapes is presented in 43.01 cut into a ruby red flashed glass of PN=III/355 (1915). The foliage of 'Blumenschliff 333' in 17.01-11 and the cutting of the leafes in 20.01-03 all show a characteristic common pattern of nearly parallel cut stripes seen again in 37. The same cutting décor is applied to the ruby red over 'Annagelb' bowl PN=III/2410/8", the shape already seen in 7.02A the


43.01                                                  43.02


'Blumenschliff 333' and related Décors continued

In 44 vases décorated by the 'Blumenschliff 333', already seen in 17, are continued. The vase 44.01 shows this cutting on a dark-blue over 'Annagelb'..


Usually the Loetz cut vases are made of quite thin glass, but 44.02 is deeply cut into a ruby-red thick glass vase of shape PN=II/8032 (J.Hoffmann 1912) and 44.03 clearly shows the thickness of the glass.


44.02                                                                                        44.03

The vase 44.04-07 and the lidded bowl 44.06, with a variation of the rose flower, are made from dark-blue cut to clear glass, 44.05 is a bowl cut ruby-red to clear and 44.08 shows the well known bowl footed on three spheres in ruby-red cut to 'Topas' yellow.


44.04                                                                                  44.06



44.07                                     44.08

The shape of 45.01-02 comes in various sizes, already seen in 8.03 PN=II/8441 and 17.05, it is one of the largest Loetz vases known, it measures H=34.5, Do=24 cm and weights 2.6 kg. The intaglio cut 'Blumenschliff' variant, with simplified leaves as compared to 44, is centered between two bands of thumbprints and crosshatched areas. The footed bowls 45.03-04 show the same simplified cutting.


45.01                                                                           45.02


A three footed bowl ruby-red cut to clear is 45.04.


The ruby-red cased 'Topas' vase 45.05 shows the same cutting as 45.01-02.


An interesting cutting design is presented on 46.01, a vase of same shape as 45.01 and many others.



Other 'Schliff 249' related vases.

The vase 47.01-02 is ruby-red cut 'Annagelb' glass, PN=II/8437 (1912), the cutting is related to the 'Schliff 249' shown in 18.02-03.

Cut 'Transparent' Glass

In the rare light-green vase 48.01 the décor - though looking like 'Octopus and/or Intarsia' glass - is called 'Transparent Glas' i.e. 'Transparency Glass' and is likely being made as follows. Starting with a mould blown green cased opal white glass, firstly, the green outer layer is grinded partly away to form leaves by the then appearing white opal inner case. Instead of grinding, etching may be used, too. Then the total vase is covered by an outer layer of clear glass - this technique is known to be used by Loetz. At the end the outlines of the foliage as well as the two circular border lines were deeply cut, again reaching into the white opal inner case and finally the gilded décor is applied. The details of the foliage and its arrangement of alternating up and down pointing leaves along a waveline branch remembers strongly onto the Loetz signed 'Intarsia' vase [Hass] shown for comparison in 48.02.

I hope, that this article provides a first comprehensive overview about Loetz cut glass production. The 188 examples on 183 photos give a good visual impression of Loetz cut glass, mainly onto the production from the begin of WW I 1914 up to 1936. Only very little is known about the early Loetz cut glass production before 1900, some first assignments are illustrated in 0.01-0.05. The sheets 2.01-06 show 80 paper patterns of Loetz cut glass and 6.06 Kralik paper patterns for comparison. Attributions of key pieces are based upon PNs, with 60 references, one early example based on it's Dek number and additional pieces have been included, based on shape and/or colour similarity. Vases décorated by the documented 'Schliff 333 and 249' as well as first examples of Ausf-276 and one vase with similar décor as shown in the advertizing sheet 2.04, are presented. The article documents many new attributions to Loetz and new cutting patterns. The cutting décors are categorized within 48 families. From the cut glass presented in this article it becomes clear, that Loetz produced quality cutted items, but did not play an important role on the development of artistically leading hollow cut glass. Only the vases shown at the Paris 1900 'World Exhibition' and the 'Werkbund Exhibition' 1914 at Vienna belong to the top produced at this time. It seems, that the cut glass was treated more in the spirit of tradidional Bohemian production without putting too much effort into the design of a very elaborate high end decoration, as compared e.g. with companies like Harrach, Moser,Val St.Lambert or Webb and Stevens&Williams. A small part of the production is quite similar to Kralik items and could obviously be misattributed. The relatively thin Loetz glass - with exception of face cut items and some late production pieces - separates it easily from the brilliant cut glass made in the US, or from modern cut glass, still made today in the 'Bohemian fashion' e.g. in Poland, Czech Republik or Turkey. The author is convinced, that with respect to the relatively large production of cut glass made after WW I, mostly for export to the US market, there will be an increasing part of Loetz cut items being revealed in the near future.



The author is very grateful to all members of the Loetz Advisory Board: Warren Galle, Andy Jelcick and David Littlefield for ongoing discussions and fruitful suggestions, and especially to the founders of this website, Deb Petersen Fitzsimmons and Tony Ellery, for their encouragement and constructive contributions as well as for carefully editing this article. I gratefully acknowledge Warren's contributios and the photos from his collection, as well as Deb's tedious search for early Loetz items, bearing at least a trace of cutting marks. My thanks also go to Mike Moir for his ongoing support. I'm pleased to thank here Ales Kral for his generous permission to use photos of his collection, well presented on the website bohemianglass.org. I am also very grateful to the dedicated collectors who kindly contributed many of the examples referenced in this article.
