Abstract

As the final surface of a piece, glazes give ceramic works their vitality through color and texture, and creating a glaze itself can be an art. Mid-range reduction glazes are fired at a mid-range temperature in a kiln where the oxygen supply is reduced during the firing. Reducing the amount of oxygen available to the flames, done by closing the vents, forces them to get oxygen from the glazes instead. This chemical reaction dramatically changes the outcome of the glaze. This is only possible in a kiln with a flame, such as a gas or wood kiln, as opposed to an electric kiln, whose heat is independent of the atmosphere in the kiln. Mid-range reduction glazes provide an array of alternative surface possibilities for large pieces that would warp if fired in the high temperature range.
