Cernit Number One Polymer Clay is the original opaque line of clay. It can be moulded, sculpted, used with or without tools, textured, printed or mixed with stones, pearls, feathers, mica powders, paints, and more. After baking, the clay is waterproof and it can be baked several times if you wish to add bits to your work. After baking, the clay can still be worked with. It can be sanded, drilled, painted, polished or varnished. Baked Cernit also keeps some flexibility and does not break easily. This is a huge asset for creating flowers, bracelets with no clasp or other fine jewelry that needs to keep a certain flexibility. Cernit does not stain hands or tools and is odorless, even during baking. Polymer clay is also a wonderful way to explore designs without risking your precious metal clay. Work out your designs in this clay before executing in metal clay. Bake and use as a mold. Use polymer clay to add brilliant color to your jewelry designs. Details: Opaque white 2 oz.
