In buying supplies for Art-al-Sol, I found a glass fusing kiln that goes into the microwave. I ordered it and tried it out with my campers. It is AMAZING!!!!!! You design a glass piece, place it on kiln paper, and place it in the kiln. The whole kiln goes in the microwave for just a few minutes. The only drawback is that you have to wait for 30 minutes before you can take the glass out of the kiln and see it. I know...patience is a virtue, one that I usually have, but this time, it was very hard to wait. I found this kiln in an art supply catalogue, but I also found it at Hobby Lobby. It's a little pricey at about $119 at H.B., but with a 40% off coupon, it makes it more affordable. I have fired my kiln over 60 times, and it is still working great!
