I want to look into the mouth of the crucible of my induction furnace to see melt progression, but don't want to present my hansom face as a target for splashes even from behind a face mask. As the crucible is suspended at chest height (it's a roll over furnace) the obvious solution is a 'mirror on a stick' - but glass probably won't survive long in the foundry. Where to find mirror polished stainless steel in (say) a 6" square?
