Pottery Plaster of Paris

Pottery Plaster of Paris

The casting methods of Korea's ceramics industry are rapidly being introduced to mechanization and automation for higher efficiency. As such, high-quality gypsum (Pottery Plaster) is in continuous demand. Sam Woo Chemical Industrial Co., Ltd. fills this demand. More than this, it puts much effort in developing new products and producing them from its immaculate production facilities, using materials of the highest possible quality, and with strict quality management, resulting in its production of high-quality calcined gypsum for ceramics modeling such as super-heat-resistant gypsum, super-abrasion-resistant gypsum, and bone china, which requires a high-degree of purity.
