This is a 240 volt potty kiln I picked up at the local
flea market for $78. It is much larger then I wanted,
but for the price I can't complain. It costs about $1
per hour to run at full temp, with a max temperature
of 2300 F. Picture below shows one slightly red
crucible ready for a pour. I have had all three of my
crucibles in it at once with room for a few more.
Very nice for large pours.
