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.

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

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
- Copper needs about 20 psi and a hairdryer blowing air into the burner.
