Melting Cans With The Mini Metal Foundry
For as long as I can remember, I've been intrigued by the idea of melting metal and making things with it. The problem has always been that it was out of reach or required really expensive equipment.
In this project I experimented with 10 different prototypes, to develop a reusable backyard foundry that melts aluminum soda cans easily and safely. I tested different refractory recipes, different containers, different setting for blowing air, and different types of makeshift crucibles.
I tried various ratios of portland cement, sand, perlite, plaster of paris, water, and even kitty litter. For containers, I experimented with clay pots, plastic buckets, no container, cinderblocks, and a galvanized steel pail.
