I have used this turquoise crackle recipe for a while
and it seems to work pretty good. You can play a
little with the percentage of copper carb, but not
much. When you take it out of the kiln let it stay
exposed to the air until you here some cracking.(we
would use a fan and turn the pot with the tongs.
spraying water makes little cracks.) Then reduce it.
Keep putting a lot of paper or straw over it to really
get it going and then seal it. If you don't want the
reduction black cracks, just leave it out in the air,

Hi,
I would like to say thanks for the help with regards to my raku problem. The
weather here in Israel is now too hot for experimentation but I look forward to
future raku firings.

Joan.
