Willi Singleton has been wood-firing his climbing kiln in Kempton, Pennsylvania for thirty years, using mostly clay taken from Hawk Mountain mixed with Stancill's clay from the northern Chesapeake coast. Singleton's pieces are mostly glazed using primarily ash/feldspar glazes. His glazes are made from corn stalk ash, bamboo ash and wood ash, in addition to creek clay from his back yard. Small amounts of silica, kaolin and oxides are also added.
Singleton is currently artist-in-residence at Cedar Crest College in Allentown, PA, where he teaches ceramics and manages the clay studio. Singleton studied Visual Art at The Evergreen State College (1981) before pursuing wood-fired ceramics in Japan from 1981 to 1987. He built his Mashiko style climbing kiln on family land below Hawk Mountain in 1987, and has maintained his studio there ever since. Singleton also recently completed an MFA in Interdisciplinary Art with Goddard College, VT in 2016.
