Anton Kothgasser, Vienna, 1769–1851, porcellain and glass painter from 1781 at the Vienna Academy of Arts, studied figure drawing with the German painter Heinrich Füger, from 1784 until 1840 at the Wiener Porzellanmanufaktur, employed there as the manucature's most significant design painter, painter no. 96. From 1811, he was devoted to glass painting beyond and independently of his work for the manufacture. He was introduced to glass painting by Gottlob Samuel Mohn, 20 years his junior, who had moved to Vienna in 1811. He received numerous rewards, a.o. on September 6, 1811 and then on May 5, 1816 the permission “to work at home for some months with his glass painting”. He initially dedicated himself to sheet glass painting, but soon turned to hollow ware painting using transparent fusing colour (transparent painting). This technique had been invented by Samuel Mohn, who engaged with it particularly in the period 1815–1830.
