Raku firing process

All of our work is designed, hand formed, glazed and fired by us. Our work is either assembled from slabs of clay, hand formed or wheelthrown. After the clay is dry, it is bisque fired in an electric kiln. Next the glaze is applied. Some areas are left unglazed.

Our primary method of firing is a process called raku. We do this outdoors in a kiln specially designed to allow quick removal of the pottery. After the kiln reaches approximately 1800 degrees and the glaze is smooth and glossy the pottery is removed. Thermal shock causes the glaze to crackle. Still glowing with intense heat, the pottery is placed on a bed of sawdust and paper which burst into flames. Then the piece is covered with a container to deprive the flames of oxygen. This produces a smoky atmosphere inside the container where carbon is absorbed into the unglazed clay and the crackled glaze. Each piece has its own distinct crackle pattern and is unique in the way the carbon darkens the clay.

Raku work is NOT designed to hold water or food.

We hope that our work gives you enjoyment and inspiration.
