I've been spending some time experimenting with heat patinas and copper. After several unsuccessful attempts, I came upon a method that works for me and gets me some beautiful colors.
After shaping, sanding, hammering, and tumbling my copper, I use my butane torch. I heat the whole piece until it starts to turn and then I quench in cold water. I then put the copper back on the fire brick and heat all over again. I may do this process several times until I get the colors I want. Next, I run the copper upstairs to the freezer and leave it in for a few hours. The pieces have come out very shiny and with lovely color variations. I'm currently using no sealer, as I'm worried this will alter the patina. Let's see what happens....
