The Amphora porcelain works existed from 1892-1945 in the Teplitz-Turn area of Bohemia, part of Austro-Hungary, but since World War I in Trnovany in the Czech Republic. It was founded by Riessner, Stellmacher & Kessel. Stellmacher left in 1905, and Kessel left in 1910. As the partners changed, the company became known by different names, but the pieces were always called Amphora porcelain. The company was nationalised by the Czech government in 1945. In their half a century of production, Amphora became known as a fine art pottery manufacturer. They produced innovative designs and shapes with a high level of detail, and were considered by many to exemplify the Art Nouveau style.
