On the other hand, many people may think that chinaware and porcelain are made of china clay exclusively. Actually, they contain perhaps only from 10 to 60 percent china clay. The balance is made up of sand, flint, quartz, and so on. The purpose of the clay is mainly to allow the article to be molded, or formed, and to impart whiteness when fired.

Did you know that china clay may not only be under your feet in the earth but also in those rubber soles or boots that you rely on to keep your feet dry? Added to natural or synthetic rubber, china clay not only brings down the cost but also increases the mechanical strength and resistance to abrasion. The result is cheaper and more durable footwear.
