A kiln is an insulated furnace or oven for firing pottery and other materials, it can reach up to 1500C. The first firing is a bisque fire, the bisque temperature is usually hotter than the firing temperature. This is to dry out the pottery ready for glazing. After glazing the pottery goes in for the second firing this then finishes off your pots.
Health & Safety

- Opening the kiln door when on prevents a high risk of an electric shock.
- Cear need to been taken when entering the room where the kiln is because although the temperature on the exterior is lower than the interior it can still reach 160C.
- harmfull fumes may be given off by some glazes especially if firing isn’t at the correct temperature.
