Hey It's me again, just wondering if there is a good book out there about
crystaline glazes? I just saw the ones in Ceramics Monthly and they are
wonderful. Thanks, Jennifer in Alpine

You know, I have a friend on the other coast who has done some work with
such glazes, she is not online, however, so i don't know how long a
reply might take. You asked the line yet? I am sure there is a lot of
stuff on chrystalline glazes available. Good luck. Sherry

I just purchased an Orton AutoFire controller for my electric kiln, in large
part so that I could control cooling ramps and experiment with crystaline
glazes. I usually fire to ^6 and use mid-range porcelain and white
stoneware. Does anyone have any good recipes for me to begin with? Thanks.

In Cooper's electric kiln ceramics he has a crystaline glaze for 2300F. It
seems to work at ^6. I've only tested one small test tile though.
Good luck!

For those of you who are interested in sharing crystalline information and
experiences, there is a monthly available, ISCA (International Symposium of
Crystalline Artists.) It's available through Don Holloway at
mailto:hodon@earthlink.net
I have more information on my site about crystalline publications,
articles, etc.

Yes, I have learned from my mistakes...
I can reproduce them exactly.

Dear Scott B. Ackerman,
Zinc silicate has to form from the mixture. To get this to happen all of =
the ingredients have to go into solution. It is important to ensure that =
all of the zinc oxide dissolves before the Willemite starts to =
precipitate. You rely on the glass in the frit to keep everything in =
solution as the melt cools. Crystals seem to grow best just above the =
glass transition temperature.
However, even though many kilns cool quite quickly when they are shut =
down, cooling may not be fast enough to suppress the rapid formation of =
crystallites of Zinc silicate, which might lead to an overall even =
distribution of very small crystals, even a matt surface. So crashing by =
200 0r so degrees helps to suppers nucleation and so you get fewer, =
larger crystal masses.
Others may have a different answer.
Best regards,=20
