Q: Are glass and glaze the same?
A: Sometimes, but not often. Glass itself dates back at least 50 centuries. Mix sand and some other dry minerals, heat in a fireplace, and you obtain a material often called a “network polymer” (a “mer” is a unit molecule and “poly” means many, joined together).
Q: What affects a glaze surface?
A: A glaze surface may be glossy, satiny, or rough (dry matt); the actual result will revolve around the silicon oxide and the alumina oxide contents, both in relative and absolute terms. A glass that contains 60% silicon oxide (silica, flint, quartz), plus or minus 5%, will usually make a good glaze.
Q: How many materials are there in a glaze?
A: If one examines many glaze recipes, one soon realizes that most of them contain ten ingredients, or less. These, in turn, are used repeatedly in different recipes for a given firing range (low-fire, mid-fire, or high—fire).
