This heart shaped pendant first started off as a 1963 Canadian Silver Dollar. It was about 80-20 silver to copper. The rough shape was made using the lost wax technique and after hours of filing, sanding and polishing the final product was finished. It was made for my gf for our anniversary.
The wax used was from a candle from the dollar store. It was heated using hot water and formed by hand. I made it a little bigger then what I wanted the final size to be to account for any shrinking and room to file and polish. The sprue (the hole made for the metal to be poured) was made extra large to be turned into the ring so it could be hung from a chain.
