[Namron] lost wax Casting?

[Rob]

Pretty different... they reach the same temperatures, but from what  
I've heard no one wants to melt metals in their kiln.  We could  
probably build a flower-pot furnace for a one-off casting.

I think the biggest difference is a furnace for melting metals is  
designed to generate a lot of heat over a small area (the size of a  
crucible) for a comparatively short time, where a kiln heats a large  
area slowly and cooks for a much longer time.  Brass melts at around  
1700 degrees Fahrenheit and I *think* kilns get up to around 2k, but  
I'm not sure that it's a good idea to open a kiln at that  
temperature. ;)
