Polymer clay is made from PVC (polymer polyvinyl chloride) and contains no actual clay at all. However, it has similar properties to clay in that it can be manipulated and sculpted. Most polymer clay needs curing in an oven at a constant temperature but there are air-drying varieties available. Oven-hardened polymer clay is generally more durable than air-dried.
There are several manufacturers of polymer clay and each product has a slightly different feel to the others. Common makes are: Fimo, Premo Sculpey and Kato. All can be used together.
Polymer clay comes in many colors, including metalics, and colors can be mixed to produce interesting effects and new colors.
