So I'm building this furnace capable of fitting in an A50 crucible for pyrolysis and incineration then an A20 for the smelt.
Judging from the prices of these crucibles which are very expensive, how long do they last? Specially when you have to use soda ash as an oxidizing and a thinning flux, or is there an alternative to soda ash?
I've seen Chinese graphite crucibles break apart after just about 50 uses and this is without the use of soda ash.
The brand that I will be buying is a Morex not Salamander. Since Salamander is not locally available.
Its a graphite-SiC crucible if that info would help at all.
