Keramik-Institut Meißen offers a pilot plant with comprehensive equipment to carry out trials for nearly all of the ceramic process in semi-industrial state. So there can get experiences for solving problems in research and development and in industrial production too.The following list shows the equipment for each part of the ceramic technology.
