Raku is the ancient Japanese method of earthenware firing. The vessel is made of a clay mixture that can withstand sudden large change in temperature. The piece is glazed with a copper and porcelain mixture that produces the many exotic colors found on the pot. It is then fired in an outdoor kiln where it is brought to temperature fairly quickly. This happens somewhere around 1950 degrees. The vessel is then removed from the kiln using tongs. At this point, it is glowing and red hot. It is now placed into an oxidation chamber. I simply use a trash can where I can seal the lid. The pieces are placed with combustible material like newspaper, straw, or anything that burns super quick.
Here are a couple photos I took of last weekend’s event.

This accounts for the marks on the glaze and the blackened bottoms. Each vessel is one of a kind because of the firing process. The chemical reaction that occurs by introducing the piece to a variety of oxygen releasing agents is beautiful and mystical.
Once the piece is cool it is placed in cold water to stop the chemical reaction. Each piece then creates its own coppers, gold, and other brilliant colors and an individual surprise. Your piece is earthenware and should be treated carefully. While it is somewhat water proof, it is not recommended to put water in it for extended periods of time. For flowers, I put a small plastic cup in the piece to hold the water, and no one is the wiser!
