Overview

This is where I'm hanging pics and info related to the furnace. We fixed the pressure issues - it turns out that my 30psi regulator is probably lying.

NEXT UP: Sand screens for filtering the sand? I need to check with Greg...

Links

  1. I started with Lionel's Furnace Kit
  2. I used ULTRA EXPRESS 70 from Empire Refractory in Birmingham.
  3. I am using this 60psi regulator

Notes on Furnace Operation

  • When you are done
    • Put the crucible back in the furnace so that it will cool off with the furnace
    • Put the plug over the hop vent hole so that the furnace will cool slowly
    • Pull the burner out of the furnace and dunk it in water to cool it off
    • Its "safe" to move a hot furnace, but be careful
  • On Copper
    • Copper needs about 20 psi and a hairdryer blowing air into the burner.
      • If the hairdryer blows out the fire, the furnace isn't hot enough yet - let it heat up at 15 psi
    • The target color of the iron crucible is Yellow
    • Copper cools off much faster in the ingot mold than Aluminium
