Excellent, but still experimenting
I work mainly with stoneware, using stains and oxides and have found that colours fade when fired at high temperatures. When Gerstly borate is added to clay it becomes watertight when fired to only 950 C, enabling the colours to remain bright. However, adding the correct percentage has become a matter of trial and error.

This is actually Gerstley Borate, not Gillespie Borate, correct?

This is Gerstley Borate direct from the United States.
