It is possible that this is Hortensja's bowl but as far as I recall they had the patterns engraved not painted but again, I may not know everything. Too bad the glassworks is non-existent anymore.
The history of "Hortensja" goes back to the 19th century. The glassworks was established in the buildings of the former starch mill and candy syrup plant - in 1889 the production of window glass and bottles started in the "Anna" glassworks.
Later, the plant became the property of the Belgian Joint Stock Company under the name "Industrial and Commercial Joint Stock Company of Emil Haebler's Former Enterprises", which also included "Kara" from Piotrków.
Over time, "Hortensja" became an important manufacturer of cylinders for kerosene lamps, window glass, and then blowing glass in the art deco style, among others, vases, vases, confectioneries, salads or carafe.
The glassworks, which in the 1970s employed over 2000 people, did not survive the period of economic transformation - the plant, despite being transformed into a company wholly owned by the State Treasury, ceased to exist in the 1990s.
