Are PG 7506 & PG 5301 really the same?

camelienrot PG 5301 PN II-5275camelienrot PG 5301 PN II-5275The PG 5301 decor is mentioned in all of the Loetz books as being the same as PG 7506 but noting that the decor numbering changes to PG 5301 in 1907.  We were not certain why the decor number changed but we knew that Loetz most likely had a reason for this and something must be different between these two decors, but what? Based on our recent in-depth research of Loetz decor ground colors, we discovered that the ground colors mentioned for all of the PG 5301 executions included camelienrot, gelb, Metalgelb and Thea but did NOT include any of the ground colors associated with the early PG 7506 executions which are: Candia, metallic-violet, metallic-red and bronze. While the decor decoration is identical in both PG 7506 & 5301, true to typical Loetz nomenclature, once something radically changes a different name or number is often assigned to that production. Hence, we present the "new" decor, PG 5301.

Celebrating's 4th Anniversary!

Over the past four years, we have presented 96 new decors , information on Museums that feature Loetz, articles on many Loetz designers, in-depth studies on Loetz signatures, cameos, early Loetz and cut glass productions, answered collector questions and much more.  During this time has remained free and fully accessible to the public.  To celebrate's 4th Anniversary, we offer something different - an article addressing examples that are NOT Loetz. Enjoy!

2 Rare Etched Silberiris DEK's added

We have several new DEK's that will be rolled out in the near future but we wanted to highlight two rare etched Silberiris DEK's first. The etched Silberiris DEKs were produced with an inner casing of colored opal glass and coated with a layer of strongly iridescent Silberiris. The Silberiris finish was then etched into various patterns of flowers, leaves and vines which are referred to as "damasc" in the Loetz decor archives.  Each of these unique patterns was assigned a specific DEK (decoration) number.  These etched Silberiris opal, "damasc" vases were likely produced only for a short period of time from 1902- 1905.


DEK 293 - DEK 293 PN II-2/596DEK 293 PN II-2/596DEK 293 was produced in 6 different ground colors: fire-red, metalic-yellow, metalic-violet, Mt. Blue, Pink or Russian-green. A Russian-green example in PN II-2/596 with "293" etched on the pontil allowed us to officially document this DEK.




DEK 294 - DEK 294 PN II-2/602 DEK 294 PN II-2/602 Several examples of DEK 294 were placed in our "Unknown Etched Silberiris" file until an example of DEK 294 was discovered in PN II-2/602 in metalic-yellow.  This DEK in this ground color is specifically mentioned as being produced in PN II-2/602.  We can find 5 other ground colors mentioned in the Loetz archives as being produced in DEK 294: fire-red, metalic-yellow, Mt. Blue, Pink and Russian-green.


PG 2/314 New - Variant


PG 2/314 New with oval Czecho-Slovakia markPG 2/314 New with oval Czecho-Slovakia mark

PG 2/314 New - These examples are technically considered an "Unknown Décor".  We don't do this often but when there are so many examples, it is important to let collectors see them so they can make a comparison. This new decor category is posted within the PG 2/314 section so the collector can compare the two executions. The "PG 2/314 New" examples often have a clear cased outer layer rather than a matte finish and many examples do not exhibit silver-yellow spots towards the bottom of the vessel. There are also ground color variations that are not found in PG 2/314 such as camelienrot (pink). Several examples of this decor include the oval "Czecho-Slovakia" mark such as the one shown here which further indicates that these examples were produced after 1918.


Extra! Extra! Read all about it - 9 New Decors and a new section on Museums!

We are excited to introduce nine new Loetz decors, three of which were identified and submitted by fellow collectors from around the world, one from the USA and two from Germany. We are also pleased to add a new section on Museums to Here we will list museums that feature Loetz art glass in their permanent collections. This section will be a work in progress as we continue to add information on museums of interest to Loetz collectors. Enjoy!

New Decors

1) PG 7579PG 7579PG 7579The original example that we had in this decor was thought to be a PG 7499 and was placed on the site in this category. While it always looked a bit different, we chalked it up to photography. Then we found another example in the same shape, PN I-7579, and the production notes confirmed our suspicions that the “thumb print” design on these two examples were a different decor entirely.

2) PG 7766PG 7766PG 7766This decor was identified by a collector who was doing research to locate the production number for a crete Papillon vase that she had recently purchased. When she located the Bakalowits shape, PN 85/3693, she noticed that a “bronce PG 7766” was included in the production notes. She then recalled that a CW article posted a year earlier presented a bronce example in the same shape, and, voila, we have a newly identified decor! Thanks, Jill and Tomasz, for letting us share your story!


3) PG 8353PG 8353 PG 8353 While researching the production notes for a lamp shade, this collector came across PN II-8353 and noticed that the paper pattern not only provided a drawing showing the identical design of the decor on her shade but also a description that matched exactly to her example. This is great Loetz research!


4) PG 85/3839PG 85/3839 PN II-2299PG 85/3839 PN II-2299A paper pattern of a lampshade showing this decor along with a description of the ground colors, spreading dark blue & spreading dark green, is shown in “Loetz Bohemian Glass 1880-1940” published by Hatje Cantz on p. 310. Later research provided documentation that this decor was also produced in opal and Thea grounds.


5) PG 85/5054PG 85/5054 PN 85/5054PG 85/5054 PN 85/5054A paper pattern of a lampshade showing PG 85/5054 along with the description: ground colors, gray, ozone; decorated with silver-yellow band and dots, is shown in “Loetz Bohemian Glass 1880-1940” published by Hatje Cantz on p. 311. Many photographic candidates for this decor were available in our library and several of these were included in our “Unknown PG” section and labeled “possibly PG 85/5054”. It wasn’t until recently that we were able to obtain an example with a gray ground in PN II-85/5054 that helped us to definitively document this decor.

6) Titania Gre. 2514Titania Gre 2514 PN II-2515Titania Gre 2514 PN II-2515This rare Titania genre was discovered by Volkmar Schorcht, a fellow collector and researcher of Bohemian art glass from Germany.





7) Titania Gre. 4615 - Titania 4615 PN II-4615Titania 4615 PN II-4615We are pleased to present another rare and beautiful Titania Genre recently discovered and identified by Warren Gallé.



8) Ausf 276Ausf 276 PN III-2209Ausf 276 PN III-2209The only reference to Ausf 276 is located at the end of “Band 2, Katalog der Musterschnitte” on p. 589 under the section “Printed Pattern Sheets”. This 1927 Loetz decor is comprised of vases and bowls in various colors that exhibit a specific cut flower design, “Blumenschliff 333”. Thanks go to Warren for finding examples that match the paper patterns for this decor.


9) Mercur/MerkurMerkur PN II-437Merkur PN II-437This decor must have been very popular because it is mentioned over 90 times in Loetz archived production notes from 1898 – 1908. Examples of this decor are hard to photograph and tend to look similar to both Norma and Silberiris. The basic characteristic differentiating this decor is a green ground with a dense silver-yellow opaque finish that has a bluish cast to it along with an orange liner that can be seen at the rim. This decor is often decorated in gold relief with a specific decoration (DEK) assigned. The production notes where Mercur (also spelled “Merkur”) are mentioned often include “Blau Iris”. Thanks to our extensive photo library, we were able to find several examples of these two decors in the same shape which helped us identify the Merkur decor.
