Custer Feldspar Chips
Chips of Custer Feldspar, added to clay at cone 10 they gush out and look like this.Recognized as one of Japan's six old kilns, the history of Shigaraki ware dates back some 1,200 years to the Nara period (710-794).
There are three points to look for when judging the color of a wood-fired, ash-glaze Shigaraki pot -- the overall color, the glass beads and dribbles formed when the heat in the kiln melts particles of feldspar in the clay, and the scorches that come when the pot is blackened by ash.
Cool!
