Dear Llewellyn
Is this a purple glaze which breaks cream or a more even purple
with cream speckles? How about surface? Glossy, semi-matte or
matte? Whenever I see dolomite in any recipe, I think of the
1970s and those matte pinky-purple glazes which appealed so much
for their "originality". They have "aged" quite a bit too!
