Our Products which are made from Porcelain clays are different from stoneware and the earthenware clays used to make vases, planters, dishware and decorative tableware. The critical ingredient in porcelain ceramics, first found in China, is the soft, kaolin clay. The clay, mixed with porcelain stone, requires higher temperatures in the kiln when solidifying and glazing ceramic wares than common earthenware or stoneware clays. Once fired, porcelain ceramic pieces develops a hard, glass-like and translucent surface on the item; it's sometimes coated with pigments and a glaze before firing.
