Firing To fire, place the piece in a cold or warm kiln (below 300ºC/570ºF). (It is safest to start with a cold kiln.) Take at least 15 minutes to reach firing temperature. You may use any of the four firing temperatures and hold times listed below. If you are combining with other materials (i.e. natural stones, glass), please check the appropriate firing temperature and hold time. |
