Polymer clay is a type of hardenable modeling clay
based on the polymer polyvinyl chloride (PVC). It typically contains no
clay minerals, but like mineral clay a liquid is added to dry particles
until it achieves gel-like working properties, and similarly, the part
is put into an oven to harden, hence its colloquial designation as clay.
Polymer clay is generally used for making arts and craft items, and is
also used in commercial applications to make decorative parts.
Art made from polymer clay can now be found in major museums.
