Pros : I absolutely love this bowl. The results of the melt are definitely one of kind. I got 5 different design elements out of one melt. There are so many things that I can create out of this melt. I can cut it for unique jewelry, wind chimes, etc, or just leave as is for a high impact piece. It's fun to have a total surprise of what your end result will look like. I bought the whole set.
Cons : I had read that it had cracked after the first use. So, I gave it a slow cool down ramp, no cracks. I still have to figure out how to cut the melting glass while it's still hot to avoid the glass cooling into icicles. It's way too hot to get in there and snip the dripping glass. So, after it cools I have to break the so-called icicles from the pot holes that are now attached to my glass. I then grind these spots where I cut the glass and then fire polish it. I will figure out a way to get rid of the icicle problem.
Other Thoughts : Totally worth it. If it cracks, I will buy another one. I melt it right onto thinfire paper so I don't have to worry about my kiln shelf. I definitely encourage a slow ramp to cool it down.
