Looking for information on how to create halos in a crystaline firing. My
sources have stated that halos can be created during the soak time by
raising the temperature at the beginning of the soak time or toward the end
but nowhere can I find any ball park figure on how much to raise the temp
and for how long before going back to the soak temp again. Is there some
angel out there that can tell me how to get my halo ?

Getting the halos is very simple, and your sources are quite correct.
Try varying the temperature by 20-50 deg.F. Hold it for 10-30 minutes.
Try various combinations. Different glazes will behave somewhat
differently. The key is to EXPERIMENT and to keep detailed, accurate
records.

Drop it 100 degrees and soak then raise 50 drop etc. The soaking temp
determines the shape of the crystal.

Joyce:
You are correct that halo's are developed by rising the soak temp. You need
to begin the soak at the crystal growing temperature (somewhere around 2000
degrees) and hold for about 45-60 minutes to allow the nucleus to develop.
The longer you soak the growing temperature, the more crystals you get.
The less time, less crystals. Then after about an hour rise the temp about
25 degrees per hour to about 2050 degrees. You then hold there for aprox. 3
more hours. This should give you the halos you are looking for. You can
even let it rise and fall a couple of times. Again, the longer the soak,
the bigger the crystals. But remember, too long and the crystals take over
the entire surface. Good luck!

I have an issue of Studio Potter that has a number of articles about
potter who do chrystaline glazes with some direction on what they do to
get the halos, if someone doesn't give you info, send me you snail mail
address and I xerox it for you
