Craft Materials/How they are produced: I start by taking one or more positive images (like a charm, small sculpture, earring, or button) and embedding it into a prepared piece of polymer clay. That makes my primary mold. I use dental tools and small picks to add shape & detail or smooth over imperfections that occur after removing the positive. After baking the mold, I am ready to make my own positive. I prepare polymer clay with the colors I feel work best, then dust the inside of the mold with pearl-ex powder (tinted mica dust). I push in the clay, taking care to add extra clay to reach deep into the mold, then after a short refrigeration, "decant" the positive, cut out the shape and add more pearl-ex powder to bring up the design. A hole is added at the rim for hanging, then I bake it. After it cools, I finish the edges with several grits of sandpaper, then mix up a special combination of water putty, acrylic medium and tints to get a rock-like color. I usually mix up 2 batches to have 2-tone rock. It gets slathered on the back of the Fossil and I let it dry. A good sanding leaves me with a rock/slate appearance, which enhances the fossil effect. I then add a head pin and a stone bead and get my pendant. Pearlescent colors range from coppers to blues, golds and pearl. Clay colors range from hot pink and purple to green, teal and navy plus pastel swirls of any of the colors are also used.
