China Clay has the chemical Al2Si2O5(OH)4. It is also known as Kaolin, and is a soft white clay used in the production of ceramic tiles. It is a valuable industrial metal. China clay was first discovered in the 1740s in England. It gets its name from a hill in China called Kao-ling, where it has been collected for centuries.

Ball clay is a really good sandy clay that burns light to near-white. They are most commonly used to make white ceramics and are renowned for their flexibility, unfired endurance, and light fired color. A mixture of minerals, primarily kaolinite, mica, and quartz, make up ball clay. The predominant colors are white, brown, and gray.
