It works similar to the bronze clay...which I love. Here are some pics of the dried clay before firing.
I ramped at full speed up to 1650 and held for 3.5 hours. Pieces fresh from the kiln with a short polish from a 3-sided nail buffer to shine up the high spots are shinnier than a new penny.
I applied a heat patina with a propane torch and ice water quench...or in this case I went outside and scooped up snow. It gives a nice color to the copper. I was using a big ass plier that I had in the garage and held the lentil a little to tightly. Pressure and heat caused the lentil to crack at the point where I had a hole for the bail.
