What are the four types of 4 kilns in pottery and why is each one used?

Answer 1

There are 3 major or say professional ceramic kilns and the rest are just modifications from these. The Salt Kiln also known as the Soda kiln which is usually for glazing and salt firing, this type is mostly for fuel firing, a downdraft kiln and fires at very high temperatures to even about 1300 degrees centigrade. The second are the Raku kilns where by they are designed in a way that pottery place in them can be pulled out at the highest temperature ranging from cone 08 to cone 04 and smoked to produce interesting surface effects on the wares or pottery. They are normally not so big in a way that there design is meant to allow easy access to the pottery wares while in the firing process as they are supposed to be put directly into the smoke when pulled out from the kiln, they are usually suitable for out doors. The third type is the Test Kiln; these are small and mainly for test purposes and experimentations on new formulas of clay and glazes. They are use to make prior checks in order to see the out comes and final results before the final firing is done. They can be fuel-fired or electric and can be placed for indoors due to there size.
