I have been looking into Heckert art nouveau glasses for some years, convinced that Heckert produced undecorated glass ware finished at the furnace around 1900. Some hints have guided me to Heckert glass. Pazaurek noted Heckert among other well known makers as producer in his book "Moderne Gläser" published c1902 (image left). Jan Mergl assumed Heckert as maker for some types of anonymous productions curating the Passau collection (Passau Glasmuseum, Das Böhmische Glas, Band IV, IV.388, p.222).
The newly discovered pattern books of Glasfabrik Fritz Heckert contain thousands of shapes. The books titeled 400 and 500 contain three sets of patterns numbered with Th (most probably for the manager and designer Otto Thamm). At the end of book 400 are the patterns Th 50 - 100. Also the end of book 500 contains pattens Th 101 - 162 and Th 201 - 250. It might be possible that the numbers TH 1 - 49 were drawn in book 300, which did not survive. Numbers Th 163 - 200 may not exist, as there is only one empty page between Th 162 and 201. Glasses of many, if not all patterns of the Th series can be found with furnace finished decors. The most often decor is the well known "Silberband", mistakenly attributed to Loetz and Kralik in the past.
Besides the Th series also regular numbered patterns in the books can be linked to existing pieces with Silberband and other decors now definitely associated with Fritz Heckert Glasfabrik.
Pattern 496/5 (book 400, page 496, pattern no. 5; see second image) is special. It states "496/5 abgeänderte Form nur für Changeant" (496/5 modified shape for Cangeant only). This shape is a key to the decor name Changeant. And the correspondent glass exists in real! (third image). Now it is safe to name the Silberband decor with its original designation "Changeant". The decor name is not limited to the green color, as vase no. 496/5 does exist in the other "Silberband colors". A collection of ruby red "Changeants" is shown in the image to the right.
