There were two layers in the kiln pan. The tan pieces were on the top layer. The best colors always come from the bottom layer. These pieces are thick too. I wasn't rolling them out. Just making balls or snakes and pressing them in between the tablet and the mold. Varing the pressure gave different thicknesses and sizes.
Here's a pic that shows the bas-relief and sunken relief of the different sides of these pieces. I'm loving these. I have to admit as I was making these I thought I was having a genius moment .... LOL .... well ... maybe not genius ... but at least a moment. A good moment!!!
I have more pieces in the studio to prep. These were just the pieces I got into the kiln before I went to bed last night.
