I was trying to figure out how I could do some of my concrete pieces smaller, when I was hit with a "duh!" moment. I normally work with PMC3, which shrinks 12-15% after firing, and I realized that I've never tried the original formula PMC, which shrinks along the lines of 30%. So I ordered some immediately, and sat down and made an orange slice as soon as it came.
What you're seeing in the photo is the PMC3 orange on the left, and the PMC original on the right. They started off exactly the same size! Pretty amazing! The clay was wonderful to work with, but I did learn that I need to make everything thicker than I have been. There was quite a bit of warping with all the shrinkage, but I was able to pound it back in shape. The original is 1 1/2" in diameter, the experiment is 1 1/8". I'm looking forward to making more stuff with the original clay.
