No, I’ve never tried it. Sterling silver and fine silver have a higher melting point than aluminum, and you might be asking for trouble trying to cast those metals in aluminum molds. Aluminum molds are fine for lead or low-temp pewter casting, but I really don’t know about silver. Jewelery makers and silversmiths generally use lost wax casting in a type of single-use, plaster investment mold – though there are some metal ingot molds available. I believe that they are made of a type of steel, and are very plain.
I’m genuinely curious myself to hear about anyone successfully casting silver in aluminum molds, and what technique they used.
