Franz Welz - Klostergrab
(Austria- Hungary, Province of Bohemia)
First let me state there is very little published on Franz Welz Glassworks. There appears to be no or little original factory records. World Wars seen to have that effect on records. The Truitts have very brief write up and some nice photos in their book “Collectible Bohemian Glass 1880-1940”. There is much more information on the website www.Kralik-glass.com by Craig Orkney.
Mr. Orkney states that “Most of the glass I am referring to in this Welz study is glass produced between WWI and WWII. A portion of the production may be pre WWI. Unfortunately, without factory records rely on, most of the dating of the work is based on provenance marks, shape, and artistic styles and colors as related to this period of Czech glass production”.
As per the site www. 20thcenturyglass.com the “Franz Welz Glassworks was founded in Bohemia in 1728 and was in production until around the 1930s. The factory was also known as Antonienhutte Franz Welz glasswork is most noted for a wide range of colorful artistic glassware produced during the 1920's & 1930's Outpt at this time was similar to the style of Kralik glass Welz glass sometimes bear the acid etched mark "Made in Czechoslovakia" and has been noted to carries labels with the words "Royal Art Glass" "Framz Welz Klostergrab". Made in Czechoslovakia", "PeDePe" or the initials "F.W.K."
What we know for fact is that Franz Welz, of Kloztergrab, Austir-Hundary was producing glass in the 1890s , possible as early as 1885. He received Patent #479,689 from the US Patent Office on July 26, 1892, for the "Manufacture of Rose or ORange Stained Glass. The Patent reads "Be it known that I, FRANZ WVELZ, manufacturer, a subject of the Emperor of Austria Hungary, residing at Klostergrab, in the Province of Bohemia, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in the Manufacture of Rose or Orange Stained Glass”
He was making a rose to orange colored glass by adding a mixture of selenium or mixture of selenium and cadmium sulfide to the molten glass.
The Rose Bowl below center was sold by James. D. Juila, Inc. on July 19, 2009. It was listed originally as "Stevens & Williams Swirled Bowl. Large Stevens & Williams bowl has a swirl design of peach and green against a white body. Bowl terminates as a heavily ruffled rim with applied frosted lip. SIZE 7" t x 9" dia. CONDITION: Very good to excellent with two small open bubbles on the interior from the making." Before the sale Julia posted this "Additional Information: This vase is not Stevens & Williams. We believe it to be Harrach. They were still incorrect. You can not blame them there is little information available on this glasshouse and pattern.
