Clay

Clay is a type of fine-grained natural soil material containing clay minerals. Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour ...

What Is Plasticity in Clay?

 · A plastic clay will not crack or break. Non-plastic clays will. The firing process for your clay is extremely important as all clay bodies "mature" at different temperatures. Essentially "mature means fired to the point for which they were formulated." As "when a clay body is vitreous, it means that water cannot be absorbed into the clay when it is fired to maturity."
