This glaze was developed in China over 600 years ago. It was traditionally used on porcelain, to obtain bright colors over the white clay body. I have developed glaze recipes for a white stoneware clay, which often results in burgundy hues. I fire this glaze in natural gas kilns because it is very sensitive to levels of oxygen and gas in the kiln atmosphere, providing natural variations in color. I also enjoy adding drips of colorants to provide more surface movement and color contrast.
Dear friend
im found an experimental technique to reach copper red glaze in electric kiln and oxygen atmosphere.

Dr. Sencer, I’d be very curious to learn how you managed to obtain copper reds in an electric kiln.
Kind regards
