One reason to build a fuel-burning kiln is to produce beautiful reduction glaze effects. Whether kilns are wood-fired, gas-fired or oil-fired, the atmosphere can be starved of oxygen to produce these effects. This article outlines the chemical changes involved in combustion, explains the important differences between these types of fuel and the implications for the design and operation of the kiln.
