Here are a few Pic's of me un-warping some of my Vegas World Tourney Chips. This is the 1st time I have done this with a C-Clamp and it worked just fine. I put the chips between Plain Ceramic's with a large washer on each end. Tightened the Clamp pretty tight and placed them in the Cup Cake Pan, so the chips would not be touching anything. In the Oven 170/175 deg, for 15 minutes or so. Let them cool on their own. They came out Great.
