I got my kiln!!! its 18" id and 27" tall, but it comes apart in 3 sections and each one can be fired by its self. Time to get back into lost wax casting
I fired it up today, very smokey and steamy. i guess it had been sitting a long time.
It only cost me 80.00 usd

so im pretty happy, I do plan on adding a digital temp controller to it so I can hold burn out times properly. funny thing is I only need one section of it lol. I wonder if you were building a furnace if you could buy one of these and just add a burner?....just a thought
