Technically, ceramics are those things made from materials which are permanently changed when heated. For example, clay has chemically-bonded water in it which will cause it to slake down (disintegrate) when a dried clay object is put in water. Once heated (fired) to between 660⁰ and 1470⁰F (350⁰ and 800⁰C), the clay is converted to ceramic and will never dissolve again. All clay is a ceramic material, but there are other ceramic materials, as well.
The glass phase that forms during the firing of a ceramic material can be thought of as the glue that holds the finished work together. The fancy name for this is vitrification – or the ceramic chemistry that transforms a clay body into a hard, non crystalline glass. Clay bodies have ranges of temperature that... Read More »
