I bought a electric lab furnace on ebay to do some casting. It's
about the size of a coffee maker and will heat to 1000 degrees C.
The inside of the furnace is cylindrical and made of refractory.
There is a carbon crucible which fits inside and has a spout. Then
there is a clay crucible but it is much smaller than the space
inside the carbon crucible - the space is perhaps two inches
diameter and the clay crucible is about half an inch diameter.
Several questions: Can I melt metals (aluminium, copper, silver,
gold) in the furnace without the carbon or clay crucibles, so the
metal will be in contact with the refractory?
Can I melt things directly in the carbon crucible without using the
Can I make a new clay crucible with ordinary clay used by pottery
hobbyists or does it have to be special clay to take the high
Can I make a new clay crucible which fits snugly in the carbon one
or is the clay crucible which came meant to be much smaller than the
inside of the carbon crucible?
Or can I make a clay crucible which fits directly into the
refractory and melt metals without using the carbon crucible?
Thanks in advance for replies.
