melting gold in a graphite ingot mold

The graphite is so heat absorbent the gold doesn't melt before the mold begins deteriorating. Pour your molten gold into the preheated graphite and you will have success. I need to post a video of this one. The trick is to 1) blacken the mold with the soot of the torch; and 2) Place the melting dish on top of the mold as you melt the gold.

Graphite shaft extraction

Metal is a very good conductor of heat and graphite is a very poor conductor. The longer the time you take, the more the graphite shaft itself will heat up and the higher the temp you can get in the shaft and the higher the risk for doing damage to the shaft. Also means the metal will loose heat a LOT faster than the graphite.
