so i want to start melting aluminum (just for the fun of it) and i'm not very handy with building homemade furnaces, so i was wondering if i could buy one online. I noticed that they sold some furnaces that melts lead, but isn't hot enough to melt aluminum, and they also sell some furnaces that melt gold, which will be strong enough to melt aluminum, but too expensive.
Aluminum melts at about 1100 degrees, so you're going to need a 1200 degree furnace. Personally, I would use an acetylene torch with a rosebud. I've melted plenty o faluminum that way, just to pass time in the shop when I was bored.
