Perhaps the best way to color the crackle
pattern in a glaze is to use either a ceramic
stain or an oxide, and refire the piece to
temp. The Chinese did this for a long time,
likely still do. The method insures a permanent
color, and, interestingly, one can be selective
regarding which crackle(s) to stain.

Hi folks,
I've been looking for a nice crackle glaze for a few years. It should be
MATT and at most cone 8.
I've tried several recipes, but wasn't very successful, either the glaze was
glossy and ran on the shelf or it was pinholed and undermelted.
So far, I gave up. Last week I tried a new commercial glaze, light blue,
smooth matt, and it gave a very nice crackle pattern on one of my clay
bodies. BUT the only problem is that the black ink I normally use dyes not
only the crackles but the glaze as well. And this looks stained and ugly. I
tried black tea as well, but this didn't work.
Any suggestions what I can use instead, which doesn't soil the glaze?
A very nice Christmas and a successful New Year to all of you.
I enjoy reading my daily Clayart Mail, it's like being a part of a big
family.
greetings from Germany

I used this product on white porcelain
which had a clear crackle glaze on it ...
did not discolor it and washes up well.
Found it in a good art supply store.

If you have a reliable crackle glaze, and time to play around:
After the first firing, while the pot is still warm, but not too hot, put a
thin wash with oxide or stain over the pot, then wipe it off. The stain
will be in the crackle. Fire the pot again, the stain remains in the
crazing, but other crackles should appear. Wash the pot again with a
different colour stain or oxide, and wipe off. Fire again. Do this a few
times with different colours, and hopefully you'll finish up with a lot of
different coloured crackle marks.
Not my idea. I remember reading about this method somewhere, many years
ago. Probably from C.M.
Cheers, and good wishes to all for the festive season.
Graeme.
