Me melting aluminum at my shop. The device is a 1200 Watt CalRod heating element embedded in a Perlite / Furnace Cement (4:1 ratio) refractory. The crucible is a ceramic jar I found at home, it holds 700 mL. The temperature is somewhere around 900C (1650F) or higher... Spent less then $50 dollars to make it.
