Once the crucible is glowing orange the foundry is hot enough to melt aluminum. Put the aluminum into the pot and turn up the power gradually until the aluminum starts to melt. The only cost here is the charcoal fuel duct tape and the 1 yard sale hair dryer. This is the melting point of aluminum 660 32 c 1220 58 f but below the melting point of steel.

Use a long metal ladle to scoop off the stuff that floats to the top when the aluminum is melted called dross. Place a plexiglass sheet on large pan and place on the middle oven rack. The large pan prevents the plexiglass from coming into contact with the hot rack which can distort the plexiglass due to uneven heating. Add low salt to make the aluminum more fluid.

The aluminum will melt almost immediately once it reaches this temperature. Once the aluminum has hardened it is still much too hot to touch with your bare hands. Preheat the oven to 250 degrees f. Blowtorch melting some aluminum sheet.

Fire up the kiln or furnace to 1220 f. This uses bbq charcoal as the fuel and a hair dryer as the blower it ll melt a small batch of aluminum in about 10 minutes. After about 10 seconds the aluminum will still be hot but safe to touch with your bare hands. Place the lid on the foundry and let it warm up.

Blowtorch melting some aluminum sheet. Add baking powder and mix to remove air and trapped gases that may cause air holes in metal later. Melting scrap aluminum into ingots 110kg or 242lb duration. The temperature in the foundry will need to be above 1220 degrees fahrenheit 660 degrees celsius.

Place hardened aluminum into a bucket of cold water using steel tongs.
