[TheForge] Metal and Pottery questions

[Paul Novorolsky]

On the subject of firing/kilns. I've been shopping around at my favorite 
tool source: craiglist. I've seen several locally, and fairly frequently 
in the $100-$200 range. I'm planning to use an Arduino to convert it for 
use as a heat-treating oven. Almost all of these kilns are the bigger, 
"standard sized" units, and I'm holding out for awhile looking for a 
smaller one.

Anyway, the point is, if you look around used kilns are available for 
fairly cheap. Pottery seems to be a popular hobby that loses its appeal 
after people sink a lot of money into it.
