Much research and experimentation has gone into the design of this kiln, to ensure the best results for separating fine gold from black sand and ore concentrates - and for smelting down old jewelry. The stacked or layered design allows for replacement of damaged pieces, in the event of spills, while the kiln can be rearranged and stacked to different heights, according to the size (height) crucible used.
