Ivan Weiss - 1946 - was trained as overglaze painter at Royal Copenhagen. In 1966 he was employed as an artist and as a student of the artistic director Nils Thorsson. The two worked closely together for almost four years. In 1970 Weiss went to Japan, where he was employed as an apprentice at a ceramist studio, where he learned the ceramic crafts from scratch. He developed artistically, and the inspiration from Japanese pottery is evident in his subsequent works. In 1972 he returned to Denmark, and was rehired at Royal Copenhagen, where he stayed until 2004. In the latter part of the period at Royal Copenhagen he designed porcelain and unique stoneware.
