    Jennifer, I haven’t tried this, but maybe you could try frits 3195. It’s bore based and melts to a very low temperature, just like GB.

    I love this glaze although it is much more turquoise when I make it with the Copper. My question is does anyone know if this glaze is food safe?

    MC 200-K feldspar– there was an article about it as a substitute for G-200 and Gerstley Borate in Ceramics Technical Vol 15 issue 2

  • Behrens Matte is similar without the Gerstley ^ 04 – 02
