300 grams Wood clay is an organic material formulated to burn clean with little residue. Shape your wood clay into any form you like, let it dry, then you can either coat it with a thin layer of PMC clay or you can paint on multiple layers of PMC paste to your desired thickness. Once you have created your base coating of PMC you can embellish your form with other elements from PMC sheet or syringe. Be sure to leave a small area of your form uncovered to allow the wood clay to burn out. After firing, you will be left with a perfect fine silver hollow form exactly the shape of the original wood clay base. Hollow forms allow you to create larger object with less PMC. Less metal clay saves money as well as results in a lighter piece, making it ideal for earrings! Wood chip clay replaces cork clay, as it is of much higher quality!
