And the nature of the clay with toughness, at room temperature, water, plastic, micro dry can be carved, all dry can be grinding; burning to 700 degrees, can be pottery, can hold water; burning to 1230 degrees is porcelain, can be completely non absorbent, and high temperature, corrosion resistance. The flexibility of its use in today's culture and technology, there are a variety of creative applications
