Begin heating the kiln on high with the fire chamber completely closed. The kiln may take 2 hours to reach raku temperature. As the kiln reaches approximately 1900º Fahrenheit open the kiln and begin loading your ware. To preheat and avoid thermal shock slowly lower the raku-firing chamber.

How long does a raku firing take?
Raku ceramics are loaded into a cold kiln, and the kiln is heated rapidly. Sometimes the cycles in which the pieces are fired are very short, as little as 15 to 20 minutes in cases, differing vastly to traditional firing cycles of around 10 hours.
What temp is bisque firing?
The bisque firing normally reaches temperature between 900 degrees and 1100 degrees Celsius. A bisque firing is a very slow gradual firing, generally firing no more than 100 C per hour. If the climb or the ramp rate of firing is too fast in the early stages of bisque, the work may crack or explode.
Why is it important not to have air bubbles in the clay?
Air bubbles in clay items are dangerous because they can cause explosions in the kiln. The air bubble dilates due to heat and forces the clay to crack or explode and shatter the ceramic piece. The risk of explosion increases with the temperature in the kiln.
What temperature does raku fire at?
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.
