Potclays Apache Red Micaceous Body Available In Store CLY

Potclays Apache Red Micaceous Body 920-1000C 12.5kgs

This clay recipe was developed by Felipe Ortega of Apache descent. It reproduces the old tradition of micaceous clay pottery from over 400 years ago. The body is composed of white mica and low coefficient red clays. Mica offers elasticity and a unique appearance. Authentic Apache characteristics are achieved when the clay is wood fired. Supplied in a 12.5kg bag.

Please note: Apache is traditionally left unglazed. Standard glazes will craze on this body due to the low thermal expansion of the body. Low expansion glazes (such as 2203 applied thinly) will be better suited.
