Stone
Shigaraki Clay
Shiga Prefecture, Japan
About
Shigaraki is one of Japan's six ancient kilns — in continuous operation since the 8th century. Its clay contains feldspar and silica particles that produce a coarse, russet surface with natural ash deposits and fire markings that are impossible to replicate artificially. The kiln environment is the co-author of every piece. No two firings produce the same result. This is the material's most important property: it resists control.
