WebJul 9, 2024 · Oxidation occurs when there is an excess of oxygen. As the kiln heats up compounds in the glaze break off and oxygen attaches itself to the glaze and clay. This causes metals in both to oxidize. Reduction occurs when there is a deficit of oxygen. This deficit creates gases in the kiln, which leach oxygen out of the glaze and clay. Historically, reduction referred to the removal of oxygen from a compound, hence the name 'reduction'. An example of this phenomenon occurred during the Great Oxidation Event, in which biologically−produced molecular oxygen (dioxygen (O2), an oxidizer and electron recipient) was added to the early Earth's atmosphere, which was originally a weakly reducing atmosphere containing red… thornes toffee
