This one was a bright blue lip wrap with a red inside. Now how this bowl ended up this was is strange due to when I put into the Lear it was fine. I asked the guy at the shop about the red that I used to make the piece and the first words from his mouth were "where did you get that color from" I pointed over to a box on the table where he told me that I could pick some colors out. He walked over there and there was one little piece left of the same red and he picked it up and threw it in the garbage. Then he stated that he thought all that red was gone and the reason was unknown why the red did not like the clear but he had used it a few times and it did the same thing and the pieces are still around and have not completely fallen apart. But I would have to say it is neat to look at that is for sure.
Here was the last piece of the day. Just an easy fluted bowl with fuchsia as the color. All I was doing here is to get something done and work on my bubble depth into the piece.

That red has Cadium in it. It is lower COE(Expansion) than the clear that you are using. It will happen with Canary Yellow from Kugler as well. It tends to happen with the dense reds and yellows that the germans make as they are geared toward the 92/94 area with lots of lead to help make them fit. The deep reds and yellows will do that.
What happens is the outside clear was cooling and shrinking at a different rate than the inside red. Thus truck loads of strain developed between the two different coe glasses and the clear gave out and shattered to release the strain.
Think of it this way, if you took some boro glass and covered it with with the soda lime glass we use it would do the same thing but it would actually explode into little pieces. Boro COE33, sodalime COE96. I would guess that RED is about COE90 or so as it was not enough to shatter it to pieces but enough to stress fracture it.
