Raku is a 5 century old method of firing originating in the orient, and may be part of the Japanese Tea Ceremony. Raku fired pottery is very porous, it will not contain water long. If using your Raku ware as a vase, please use a plastic or glass liner.
The pots are fired to about 1700° F, removed from the kiln “red hot”, and placed in lidded cans lined with combustibles (sawdust, paper, etc.), which ignite on contact. If using a metallic glaze, this is where the colorful changes occur that make each piece so unique. As the dancing flames consume oxygen and enhance the colors of the metallic glazes, the copper shows a rainbow of hues. Carbon from the smoke will be absorbed by any unglazed area, providing a dark contrasting finish. (See "Play with Fire" on the About Us page.)
