hello!

On behalf of a fellow potter, I'm requesting any recipes out there
for a white crackle raku glaze. I enjoy the Clayart line. Thanks, Jan

Jan,
There is a simple starting point for a clear raku crackle.

80% gerstley borate, 20% neph sy. To make white, add tin oxide from 2%
to 10%. Make a small batch, see how you like it.
