lead weights?

can I use silicone molds for molting lead


Hi Micheal,

Lead has a melting temperature of 621.5º F / 327.5º C which is too hot for the silicones that I'm familiar with. Smooth-On makes a product called Mold Max 60 that will withstand up to 560°F / 294°C which would work for tin and pewter, but not lead I'm afraid.

Sorry I don't have better news for you!

Best,
Paige

Thank you Paige I thought so and I will keep on making molds from melting aluminium cans they can withstand the high temperatures ,but like your class and will continue to log in for more
