Art Clay Slow Dry 20g

A slower drying form of Art Clay silver and can be worked for up to four times longer than standard Art Clay 650.  Just like Art Clay Silver 650 it can be fired with glass, some stones and fine silver. You can fire it with a torch, on a gas stove, or in a kiln. Simply shape your item, leave it to dry, and fire it  and the result is a pure silver piece. This pure silver piece can then be hallmarked as fine silver (another name for pure silver) at any UK Assay Office.
