I like Bee-Dubya's solution. His instructions aren't bad either, but his solution'll keep you kickin' stumps for a week.

(You don't think that he really only uses them kilns for pottery, do you? The "waste heat" is used to run off some of the best alligator pizen to outa Floribama. He's an up-to-date multi-tasker and energy-star efficient dude!)
