One of the great Loetz mysteries is the decor name for the Loetz “Heart’ vase.  While not a rare decor, it is still highly sought after by collectors because of its beauty as well as an appreciation for the technical difficulty required to create this decor.  Several examples of this decor are known to exist so it must have been a popular and treasured piece of art glass when it was originally introduced which was assumed to be c1901-1902, a time period when many of the Loetz archives were lost. Still it seems sad to keep calling these beautiful examples, “PG Unknown”,  which is why the Loetz Advisory Group continues its research and is always on the hunt for examples that might one day match a shape that could lead to the discovery of a new decor.

Recently at auction, a Loetz "heart" vase was offered in a shape and size that had been flagged as representative of a "hyacinth PG 3/492" production.  That shape was PN II-1036. While several shapes that included production notes for both rosa and hyacinth PG 3/492 had also been flagged, matching at least two photographic examples of the same decor to shapes that also specifically list that decor name in the production notes can be difficult but this is the criteria that the Loetz Advisory Group has set for documenting any new decor. Always hopeful, a search of the photos stored in our photo library of Loetz heart vases began to see if a match of other examples could help document these as belonging to the decor category known as “PG 3/492”. 

Then,voilà, three additional photographic examples of heart vases were matched to production numbers that included the correct size, color and shape for each example along with the mention of "hyacinth PG 3/492" in the production notes. Interestingly, we also learned that this decor was first introduced in 1903. The four documented examples of "PG 3/492" are shown below and all of the photographic examples of this decor in our library have now been uploaded on  Enjoy!

(It must be noted that without access to the indispensable book, “Loetz Series II Paper Patterns for Glass from 1900 to 1914”, by Jitka Lnenickova, years of work saving photographic examples of Loetz and the willingness to share those examples and continue our research to connect these clues, many of these Loetz mysteries would remain hidden for another 115 years)

DEK 474While doing research for a fellow collector and friend on a piece that he recently acquired and thought could be the infamous "Fuxit" decor, Fuxit's true identity was revealed. Unfortunately, for my friend, his piece is still a mystery but the research process employed to reveal "Fuxit" remains the same.

Loetz often described decors using colors (i.e.: weiss marmorirt m blattgruen Asten orangeopal Perlen) as well as simply listing "Ausf 33" in the production notes. In these cases, researching photographic examples, matching them to production numbers and seeing which decors mentioned in the production notes best match the decor descriptions and/or the decor name or Ausf or PG # is how we can usually connect the dots to document a new decor.  

In this case, a slight diversion was required.  When "Fuxit" was mentioned in the production notes, we noted that often a DEK was also mentioned. The DEK's that were noted as being applied to "Fuxit" included: DEK 472,473, 474, 475, 480, 481, 482, 483, 484, 486 and 487. The "Fuxit" decor was also occasionally listed by itself without a DEK and even noted "ohne" (without) DEK.  Another clue that we noted was that many of the production numbers that included the "Fuxit" decor also listed "Aventurin" as being produced together with the same DEK that was applied to the Fuxit production. 

Recently, we completed a large project adding several new DEK's to the site. This new information allowed us to narrow our search considerably by first searching for the DEK's that were applied to the various Fuxit examples produced and then matching those examples to specific shapes.  In this process we were able to match four photographic examples to a specific DEK that also matched a production number listing "Fuxit" as being produced with that DEK and in that shape.  This research revealed that "Avenutrin mit Blau" = Fuxit!

 These four PN's include:  PN II-917 DEK 474; PN II-981 DEK 473 (Thank you, Ales!); PN II-1105 DEK 474, and PN II-913 DEK 474 & no DEK.  Of course, none of this information would have been possible without the indespensible book:"Loetz/Series II, Paper Patterns for Glass from 1900 to 1914", by Jitka Lněničková. Enjoy!

DEK I/161A 5 year project is finally completed!  There are now over 100 DEK's in the "Painted and Gold Relief” section with more examples of early Loetz DEKs soon to be added. As most of you know, Dr. Hasselbach and I have been collecting photographs of Loetz decors, shapes and decorations for over 13 years.  In that time, we have managed to acquire over 32,000 photos of Loetz. But only 6% or 2,000 photos are of Loetz “DEK’s” and less than 1% of those DEK photos have identifiable marks on them.  Realizing that one documented DEK mark can help reveal many examples and knowing how rare it is to find one of these marks, makes our research and your DEK photo contributions even more important.

Decors and shapes are much easier to document than Loetz decorations (DEK’s), especially the “Painted and Gold Relief” decorations.  Because these DEK marks are applied on the bottom of the piece and usually with a delicate gold paint, most have not survived after 100+ years.  This means that while we may have many DEK photo examples in our library, most cannot be documented.  Luckily, there is one place in the world where there are hundreds of preserved Loetz DEK examples, the Glass Museum Passau!

Early in 2015, my husband and I contacted Peter Höltl, the owner of the Glass Museum Passau, to request permission to research and photograph their vast collection of Loetz DEK examples in the hopes of finding some of these illusive DEK marks.  Permission was graciously granted and we scheduled a trip to meet with Herr Höltl at the Glass Museum Passau in June of that year.  We were able to remove and examine each of the “Painted and Gold Relief”, “Etching Ink” and “Etched Silberiris” examples from the museum’s cases.  We took over 1,500 photos and found at least 30 preserved marks, 20 of which represented the discovery of a newly documented DEK.  Each time we would turn over a piece and find a mark on the bottom, it felt like finding buried treasure. Discovering twenty newly documented DEK’s might not seem like much, but when you view some of the new examples added to the site such as DEK 57 and I/161 and see how many examples we can now match to these DEK numbers, it really is exciting.  We are all indebted to Herr Höltl and the Glass Museum Passau for their preservation of this glass and their willingness to collaborate with members of the Loetz Advisory Group to help bring this history and information to Loetz collectors from around the world.  Without the generosity and kindness of Peter Höltl, the Glass Museum Passau, and fellow collectors who are willing to share this important information, much of the history and documentation of this glass would remain hidden and unavailable for the next 100 years. 

 Many of you have sent links and/or photographs of DEK examples that you own or have found in the market place. I apologize if I have missed recognizing some of you and would appreciate it if you could remind me of your help in documenting some of these rare and illusive DEKs.  Your continued support of Loetz research and your patience waiting for these new DEK’s to finally be posted on is most appreciated.  From now on adding a new DEK will be much easier as I will only have to add one new category at a time instead of 100!

Note: The introduction in the “Painted and Gold Relief” section and the “DEK Anomalies” section will help explain many of the nuances found in this DEK section. For example, while DEK I/170 is often decorated with beautiful, exotic birds, this DEK is identified not by the various birds placed on the objects but rather the beautiful spider mums and colorful glass cabochons that decorate these vessels.

Thanks to friend and fellow collector, Volkmar Schorcht, we have another new Loetz decor, Silveria.  This decor was originally placed in the Texas category but as soon as Volkmar presented 4 examples of Silveria along with their respective paper patterns, it was easy to document this new decor!  Thank you, Volkmar!
