How hot is raku firing? Western raku is typically made from a stoneware clay body, bisque fired at 900 °C (1,650 °F) and glost or glaze fired (the final firing) between 800–1,000 °C (1,470–1,830 °F), which falls into the cone 06 firing temperature range.
Who invented raku? raku ware, Japanese hand-molded lead-glazed earthenware, originally invented in 16th-century Kyōto by the potter Chōjirō, who was commissioned by Zen tea master Sen Rikyū to design wares expressly for the tea ceremony.
