A. For spec on Red silicone see http://en.zhermack.com/Industrial/Jewellery/prodotti/HT_33_Red.kl Lead melts at 600.61 K, 327.46 °C, 621.43 °F this would be too high for most silicones. Try the heat resisting silicone, see http://www.fredaldous.co.uk/heat-resistant-silicone-rubber-250g.html You can make simple moulds using cuttlefish bone from a pet shop. Because cuttlebone is able to withstand high temperatures and is easily carved, it serves as a mold-making material for small metal casting. Prepare cuttlefish bone for use as a mold by cutting it in half and rubbing the two sides together until they fit flush against one another. Then the casting can be done by carving a design into the cuttlefish bone, adding the necessary sprue, melting the metal in a separate pouring crucible, and pouring the molten metal into the mold through the sprue. Finally, the sprue is sawn off and the finished piece is polished.
