Just using a beginner kit and a microwave. Very primitive, just for fun really.

Fuseworks beginner kit (http://www.google.com/products/catalog?hl=en&q=fuseworks+kiln&cid=10613009011215566275&sa=title#p) you can get it at Hobby Lobby for cheaper (if you use the 40% off coupon you can print off their website every week).
