For some reason the two layers of glass didn't get like each other so the top layer did a runner and jumped off the bottom one trying to escape from the kiln!
I put the piece on my block of wood and started to get another piece ready when I could hear a popping sound and then felt a sharp feeling on the back of my arm like someone was stabbing my skin... to discover it was pieces of broken glass flying up off the block as it was cooling! Ouch!
So it's back to the drawing board on this one. Not sure why the glass reacted the way it did - I guess it is just one of those mysteries of life which will remain unsolved!
