You can make hollow beads and sculptures using PMC+ Paste and Cork Clay. Cork Clay is a non toxic modeling product that is an excellent core for making silver clay beads, sculptures and other hollow forms. Save some silver by making your shapes hollow. It's easy!

Directions:

1. Form the cork clay into your desired shape. Set it onto a base like a metal tool.
2. Let the cork clay completely dry. It is important that there is no moisture left. This can take up to 12 hours. You can sand or file the shape after it is dry.
3. While holding the cork clay form by the metal tool base, apply the PMC either by paint brush or syringe. Allow the layer to completely dry before applying another layer. Apply upto 10 layers for strength.
4. File or sand any sharp areas on the dry silver clay. Touch up as needed and dry again.
5. Once dry, you can fire the item by torch or kiln. If the project is any larger than a bead of ½" diameter,  kiln firing is recommended for your safety. Avoid torch firing anything that will produce a large flame and lots of smoke.
6. Cork clay will produce smoke as it burns. Always fire this product in a well ventilated area. Do not open the kiln during firing-the extra oxygen could cause the fire to "flash" and endanger anyone near the kiln. The fumes are non-toxic, but avoid breathing it if possible.
7. After firing you may notice a small amount of green ash or residue. This can be rinsed off with running water.
8. Polish the project with your wire brush and finish as usual.

Cork Clay Storage:

1. Keep all unused portions in an air-tight container such as a zip lock bag. Cork clay cannot be rehydrated.
2. Store at room temperature. Dark spots (mildew) may appear, but will not affect the performance of this product.
