Step 1: Furnace
Check out your small gold melting furnace, make sure to clear out any debris and set a refractory brick in the middle of the inside. The brick will serve as a shelf you will place your crucible onto.

 

Step 2: propane gold melting furnace
Get a full tank of propane as running out of gas in the middle of your process is really sad. Place the propane tank as far away as possible from the furnace to prevent the heat from getting to the tank.

Step 3: Gas Flow
Open the propane tank with the valve on top. Open the regulator and keep in on high. You will need a substantial amount of fire in order to keep it going once the air is introduced.

Step 4: Ignite!
With your gas line open and the venturi air vent lid closed light the fire! You can use a match and throw it in the furnace, I like to use a map gas torch as it allows a little more space between me and the ignition of a large fire. The fire should be big and come up to about chest height.

Step 5: Introduction of Air
With the air vent lid closed plug in the motor. You will hear the motor running but it will not affect the fire until you open the air vent lid. When opening the vent lid do it gently, and just a little bit at a time until you hear a big Hwooosh sound resembling a jet engine

Step 6: Melting Metal
Aluminum has a low melting point so it is fast and easy to melt. Use aluminum scraps of whatever kind you can get your hands on. Smaller pieces arranged with some space around them are much faster melting then a big hunk of it.
