Anton Kotgasser, Vienna, c. 1820 (Ru)

Anton Kothgasser, Vienna, 1769-1851, porcelain and glass painter, from 1781 at the Kunstakademie Vienna, studied drawing of figures with the German painter Heinrich Füger, employed at the Viennese Porzellanmanzfaktur from 1784 to 1840, as its most significant design painter, painter no. 96. From 1811, he dedicated his attention to glass painting next to and independently of his work for the Manufaktur. He was introduced to glass painting by Gottlob Samuel Mohn, who was twenty years his junior and moved to Vienna in 1811. He received numerous rewards, including a.o. on September 6, 1811 and on May 20, 1816 the permission to 'work on his glass painting at home for several months'. He initially worked on sheet glass painting, but soon preferred hollow glass painting using transparent enamel paint (transparent painting). This technique had been invented by Samuel Mohn, who focused on it in particular during the years 1815-1830.
