Hi Nick
I am in England and also use PMC, I have two kilns. One for my glass which I can also use for PMC if I have large batches That is a big kiln. My other is a small beehive kiln which is tiny no controls at all.
You put the PMC piece in the small kiln, shelf is about 2 inches in diameter, switch it on and let it cook for about 20 minutes and then switch it off. Its brilliant, it works and it cost me less than £200. It is also very good for making Keum-boo which is fusing gold to PMC.
If you want any more information please contact me
Regards
Sandra
