Vitrium™ Clay is an air-dry resin clay that allows you to create lightweight, one-of-a-kind jewellery projects. The versatile clay can be rolled to a very thin layer without cracking for intricate designs. Transparent white clay can be used as is, or mixed with pigment to create a myriad of custom colours. Simply add a touch of oil, acrylic or watercolour paint or use just a dot from a coloured marker or ballpoint pen and mix until blended. Vitrium Clay dries to a firm but still slightly flexible texture.
