You are correct a melting furnace, sometimes my head locks onto the wrong words.
But yes, that is exactly what I was asking about, my wife bought me a devil forge gas melting furnace, an been trying to prepare so I do it right.
Very new to the craft here...
but, on many videos I notice some sort of base on the bottom of the smelters that the crucible is set on...is this necessary or just a good idea to help with heat distribution?
Also, what would the material be? A ceramic brick or fire brick?
Any help appreciated!
