Raku glaze is specifically designed for raku firing at Cone 05 (1888° F, 1031°C). Once they reach temperature, turn off the kiln; let it cool to about 1700°F, 944°C before you pull the pieces out of the kiln with the tongs. Raku glaze can be applied in a variety of different manners, such as brushing, dipping, spraying, etc. , on non-functional pottery and sculpture. These glazes will result in highly colorful and interesting glaze effects resulting from the glaze reacting with the intense heating and cooling regiment of Raku firing. No two finished pieces will ever be the same because the metals and colorants of the glazes are brought to the surface by flame and reduction. These liquid Raku glazes are lead-free
