Pros : Easy to figure out how to set it up
Cons : Making sure the kiln paper covers completely. After firing, there was what look like it had been burned, eventhough there was no glass touching the mold.
Other Thoughts : I was not happy with the final results after slumping. It looked really cool, but the glass strips melted all the way down to the kiln shelf. Fortunately, I put kiln wash on the shelf. I checked to see if I didn't use the same slumping schedule as I usually have, and I did. It ended up being a really cool piece, but not what I wanted to happen. And that was a disappointment.
