This is two layers. You can't see underneath, but it's strands of white glass.
The top is celadon with an accent stripe of cobalt blue.
About 9 inches in diameter.
Tomorrow, I'll place it on a mold and slump it into the bowl shape.
I'll show you tomorrow.
In the photo, the small squares surrounding the round disk are pieces of glass that I use to hold down the kiln paper that the disk is resting on. If there were no weights on the paper, it would curl up around the piece when it gets to firing temperature.
