reduction. The piece is then fired in the kiln at lower temperatures until the slip has dried, and then further fired to . At this point, the piece is removed from the kiln and placed into the reduction chamber. In reduction the carbon will soak into the clay where the slip has cracked and turn black, but where the slip is stuck on the clay will keep its natural color. The slip can be easily removed by hand from the cooled piece to reveal the design. Horse hair: Horse hair decoration is a process where the piece remains unglazed; when it reaches temperature in the kiln it is placed in the open air rather than the reduction chamber, and horse hair is strategically arranged on the piece. The horse hair immediately burns and leaves thin linear markings on the pottery. In literature Hiroshi Teshigahara made the film Rikyu, which is a nearly documentary story showing how Sen no Rikyu met Chojiro, who made the first genuine Raku tea bowl (chawan) and how Rikyu trained the shogun Toyotomi Hideyoshi in the tea ceremony with Raku chawans.(Ashton D 1997).
