I just recently completed another small dish. This time, with a checkerboard pattern. This one worked out rather better than my previous dish. In part, it was because I got the timing right this time, but it is also because I used two layers (the checkerboard is one layer, and there is a clear cap layer on top which helped to force the checkerboard pieces to fuse together).
Incidentally, I had a question in e-mail about this: the checkerboard is actually made of separate 1 inch square pieces of glass, individually cut. Sadly, I don’t have the handy tool to make these kinds of cuts quickly, so I had to do it the old fashion (that is, tedious) way.

Very cool! Both of them. I like the colors, and the one that didn’t work out right really is interesting. Kind of a study in negative space and pieces vs. the whole.
Will you put up a picture of the kiln?
So did all this come out of trying to make a glass telescope lens?
This is very neat that you’re doing all this art. My art consists of making rivers out of washable paint in Sunday School (studying John baptizing Jesus in the Jordan), with the artistic part being adding some yellow paint to the green paint to make a yellowish green water color along with some glitter glue for sunlight.
