Copper Pouring 2

[doinen]

really like the forge! I've also made a charcoal driven furnace but I've yet to melt copper. I've tried once but the coal burned up too fast. what kind of coal are you using?

[alexcorn]

@doinen Do you mean you use the kind of charcoal meant for BBQ grills? That does burn too fast, I used it too when I first started out. You need to find real coal, the kind used to heat buildings and generate electricity. It will burn much hotter and much longer than charcoal.

@alexcorn Thank you very much for the help =D

What do you use as a "cup" for the molten copper?

[alexcorn]

@R1pperB, we use what's called a "crucible." It is made of clay and graphite and can be bought from a company called Rio Grande for about $50.

keep setting that crucibel on the ground and its going to blow up seen it happen to many times and if your not in the correct clothing its painful

how did you guys make that firns

[Webd339]

Hey i was wondering where you got your coal at and if charcoal would work if enough air was forced into it? also where you got ur crucible at?? and also if after you pour the copper if it oxidizes badly?? and if so is that oxidation just on the outside??

Crucibles in all sizes = eBay!

wow how long did that take to cool down? and what did you guys use to get the fire that hot? just barbeque coals and bellows?

[alexcorn]

It doesn't take a long time to freeze...about thirty or forty seconds. Cooling takes 30 minutes or so, but we usually wait about five and then quench the ingot in water.

To get the fire to 2400+ Fahrenheit, we use coal (not barbecue charcoal) and a bellows (an old leaf blower or bathroom vent fan works fine). Nothing else is needed.
