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 "cure inhibition"?

For example, applying latex, urethane or silicone rubber directly over a model made of clay containing sulfur will result in cure inhibition. The sulfur in the clay is preventing the rubber from curing. The rubber may appear fine on the outside, but anywhere the rubber touched the clay, it is sticky and will never cure. Remedy: Apply a suitable ...

How Temperature Changes Clay

 · All clay bodies contain some measure of carbon, organic materials, and sulfur. These burn off between 572 F and 1470 F (300 C and 800 C). If for some reason—such as poor ventilation within the kiln—these are not able to burn out of the clay body, carbon coring will occur. This will considerably weaken the clay body.
