Create copper jewelry or metal jewelry such as Mokume Gane and Nerikomi

Art Clay copper can be burned in an electric furnace with or without the use of carbon or even with burner for 30 minutes, resulting in parts with a purity greater than 99,5% copper. After burning it is necessary to use a deoxidation solutions because copper oxidizes a lot.

Firing in 2 stages:

1. In the first stage, put the pieces to burn, in the oven at room temperature, and raise to 450 ° C and keep for 2 minutes.
2. Once the program is finished, cool the pieces and put them buried in a container with activated carbon (3cm carbon - the pieces - covered with carbon up to the top)
3. Put the container in the cold oven and raise it to 900 ° C - 970 ° C and keep it at this temperature for at least 2 hours.
