Aha!
Hey Ron! It worked! This last firing worked (no crackle, so far), with the
7th glaze I tested, using your recommended firing schedule. I also applied
it thinly, and fired to ^4. Will try it out with those other tests too,
#1-6, especially ones that don't have gerstley b in them.
Thank you ALL, for your helpfulness with the idiosyncrasies of clear
glazing. I have been SO slap-dash about firing - my other glazes were easy
to fire, and got casual about firing, UNTIL I got it in my head to do a
clear
glaze on these mugs with this persnickety clay (actually, the clay throws
beautifully- it just doesn't like clears!)
I've been on this list less than a year, mostly listening, occasionally
asking a question, and I've never properly introduced myself - sorry! Better
late than never:
My name is Jeanne Stolberg, living in Sitka, Alaska for 23 years. Have taken
some classes in clay, and a sprinkling of workshops, but for the most part,
self-taught. Have been working with clay since the mid 80's but there is
always so much to learn! (Especially about glazes and firing - my weakest
area) Majority of my work is wheel-thrown, but am playing with slabs too. My
studio is very small - 11 ft x11 ft.- a separate room, just off the mudroom,
(my overflow room) in the house. The kiln is under the house. Someday would
like to have a separate kiln shed.
Currently fire electric kiln to ^9, but am trying to change to ^4-6, hence
my problems!! You wouldn't call me a high production potter - and in recent
years, very little production - so busy with other stuff! Am also dance
director for a performing Russian folk dance group (Sitka was once the
capital of Russian-America, so there is historical reference), which can
sometimes take up more time than I'm willing to admit, (that, and all the
daily domestics!).
Sitka is on an island in the S.E. part of Alaska- borders on Canada, in a
rainforest environment, the climate is much like Seattle or Vancouver, but
just a slight bit more wet and cold. Very little snow here, contrary to what
people think of Alaska in general. We get a lot of cruise ships here in the
summer.
Our home is on a smaller island within sight of Sitka, (But we do have
electricity via submarine cable, and phone, via antennas - so my internet
hookup is sloooooow - 2400 bps - nope, that's not a typo error - but hey-
better than nothing!)The daily commute to take my son to school is by 17'
skiff - takes about 7 minutes from dock to dock.
There is a small group of potters in Sitka- (pop.
9,000) There is a University of AK Southeast here, that has an excellent
ceramics dept now, with the arrival of a teacher last year. I took a raku
class from him last summer, which has got me going on raku - like it!
So after a few years of low production, I'm starting to get back into it.
This weekend I'll be selling at a 3 day market, in conjunction with
"Whalefest", a
conference with events relating to the subject of whales and other marine
mammals, held here every year in Nov. (And no, I haven't seen any potters
recently chasing
whales with diaper-nets!!)
If you've made it this far, hope I haven't bored you too terribly.
Love clayart and all the helpfulness and support it provides! Thanks!!!
Jeanne S.

Hi Jean,
Send me the recipe for the 7th glaze - I can then give you a better idea
about which of the others will not craze.

Hi Ron, here is the recipe for 7th glaze:
44.6% Colemanite (I used gerstley B)
26.79 EPK
28.57 Silica
This is a recipe from article on Les Lawrence in Ceramics Monthly - issue
unknown. I noticed that he applied this glaze on ^04 bisque. I have been
doing 05 bisque. Maybe I should try 04.
Thanks!
Jeanne S.

Jeanne,
We used to use that Les Lawrence glaze - it had the distinction of being
the only one that didn't craze on mid-range porcelain, but it had a
yellowish cast and reds burned out from underneath. (Also, I imagine it
would be a bit soft.)
One thing that I haven't got around to trying properly is adding 2-3%
zircopax to a crazing (but close to ok) glaze - which may stabilize it
without making it foggy - hopefully.
