The second casting that I did with my first-smelt copper produced the ‘Manx cat’, a mouse, a pudding charm of the Christ child and two partial shells.
The mouse and the pudding charm were the more successful pieces. I have ordered a different kind of casting ring for the shells, to see if that is more successful. The shells are too fine for a conductive metal like copper, which tends to cool before completing the mould.
It is exciting using metal that you have ‘made’ yourself.
