CORNWALL ENGLAND CHINA CLAY PIT
China clay, as the name suggests, is a material known as kaolin, which was first used in China more
than ten thousand years ago to make fine white porcelain. Some of this eventually made it's way to
Europe, where the gentry still had to make do with crude earthenware pots, and porcelain was highly
sought-after. Noticing a gap in the market, a Plymouth apothecary called William Cookworthy began
to research the porcelain-making process and spent several years searching for a material that
resembled the kaolin that had been used for so long in China. In 1745 he eventually found it, at
Tregonning Hill, near Germoe, in Cornwall, where a rare type of decomposed granite, finer than most
talcum powders, arises naturally.
This material was known locally as Moorstone, Growan and Growan Clay. Cookworthy found a way
to seperate the material, using water to remove impurities, and then spent another twenty years
developing his own recipe for making porcelain, which he succesfully patented in 1768. Cookworthy
immediately established the Plymouth Porcelain Factory, and began making fine china to sell to the
gentry. He also began to sell the raw material to other English potteries.
