## Questions & Answers

**Q: Would these crucibles work safely in an electric resistance furnace (Kanthol coils, or ceramics/pottery kiln for example)?**
A: I can't say for sure.... the pottery kiln I'm guessing for sure they would work. As for the electric resistance (kanthol coils) as long as the graphite can't contact the coil they should be ok , 
    I use mine (2) in a homemade wood pellet foundry that gets super hot when I start forcing the air in.... These crucibles have handled a few occasions of me not being patient and with little to no preheating put them right on the fire and they seem to be fine...  Remember to flux them first....

**Q: Do i preheat it to 400 C or F for an hour?**
A: I have no way to measure the temperature. Just know that I heat it slowly nd it has tolerated the melting of brass well.

**Q: Worst case scenario if I tried melting aluminum in a charcoal forge with this product?**
A: I use mine in a pellet burning furnace

**Q: Instructions say to cure crucible in oven with borax. But borax melts at 1,369*F. Does it mean foundry instead of oven?**
A: I just put mine in the house oven and set it for max temp.  I set the oven to "self clean" which heats and holds higher temp.  seems to have worked fine.
