Hi Guys
I'm converting and old 9kg (20lb) gas bottle into a furnace.
I think I will use a #6 crucible size (4 1/2 - 5 in diameter) all be it home made from steel.
If this is the right size then how much gap do I leave between the crucible and the refractory sides for efficient heating and circular hot air flow?
This is for a gas fired furnace.
Cheers
Phil
