In ceramics everything works together – clay, glaze, and heat interact so that any change in one area of the kiln affects
the others. The type of clay used dictates the temperature at which finished work is fired.
Now days there are plenty of firing choices. There are high –fire stone wares that mature at 2305F to 2419F.
Glaze Firing. There are two atmospheres that may develop in a kiln as it fires – oxidation and reduction.
If you shut off most of the air, the incomplete combustion produces smoke and carbon. This incomplete combustion
will create a reducing atmosphere. The oxygen will be drawn from the clay body or from the oxides in the glaze; they are
then said to be reduced. For example, copper oxide fired in a oxidizing atmosphere will turn green, but in a reduction
atmosphere it becomes red. Ash and crystalline glazes are fired at gas kilns at reduction atmosphere.
