Heh. I was making tantalum carbide in school with a vacuum furnace that ran at 6V. There was however about 2000 amps though going through those graphite heating elements. It was at least 1800C - the peephole in the door projected a nearly white light across the room.
The safety lesson was, besides the heat and the (related) importance of keeping the cooling water on, you can touch the conductors but for god's sake don't drop a wrench on them. You'll get blowed up.
Electricity is strange...
