Recently, I saw Grant Thompson(AKA The King of Random) 's mini-metal foundry. The profect was to cool to pass up on, so, I made one and was pretty pleased with the results. Following, is documentation I did in the form of pictures and a video.
Actually, the green foam didnt work but the picture
was a good way to explain the parts of a casting model.
The final product, a necklace made completely out of soda
cans includig the soda can tabs(Also from Grant). Learn more at
