Crucibles

Crucible life is variable with type of crucible material, type of melter and atmospheric exposure. Remember the crucible is a reservoir for oxide and flux buildup. If the buildup is too great, it will cause more silicon to surface, fighting off these accumulated oxides, thus compounding the problem. Pure graphite crucibles seem to be the most susceptible to breakdown. Many electric melters use these crucibles. We recommend clay-graphite for gas melting. They provide excellent wall strength for hand pouring.
