Apache’s micaceous clay. The recipe of that clay comes from the Apache descent, Felipe Ortega, placed in New Mexico, and it reproduce the old tradition of micaceous clay pottery over 400 years ago. The body is composed by white mica and low coefficient red clays. Mica confers elasticity and makes pottery immediately identifiable. Its original Apache character is achieved after wood firing. Available in extruded body (moist form).
