On display here I have three types of raku. One is a western-style raku usually involves removing pottery from the kiln while at bright red heat and placing it into containers with combustible materials. Once the materials ignite, the containers are closed. This produces an intense reduction atmosphere which affects the colors in glazes and clay bodies. Also, there is horse hair raku. Out of the kiln an placed on a brick hair, feathers, sawdust, etc. are placed against the pot. They burn and leave an imprint of there form on the pot. With Obvara raku the piece is taken from the kiln and dipped or sprayed with a fermented liquid.
