I have been really enjoying all these ^6 glazes.
I wish people would kindly indicate if the glaze are for Oxidation or
Reduction...
We will soon have a gas kiln up and running. Just the usual wait for
the coordination of architects, electricians, plumbers, fire
marshalls,contractors,more electricians, more plumbers, etc.... etc....
If they only had listened to the dumb teacher with 25 years experience
with kilns they could have saved $7000+ (installing then uninstalling
then reinstalling). Tried to tell them you could not have a 25 foot
horizontal duct run and sufficient draft... (same contractors who put
the drain in the shallow end of the new pool) Oh well.

Charlie...If you are still in need of help with the overall plan for your
kiln instilation or its construction I may be able to help. I hate to find
out some potter is having to deal with these people. They usually try hard
to help but I have found out from experience that they don't have any concept
of how a kiln operates or what is needed for it to function properly.
Ive been building kilns for myself and others since the 60s.
Drop me a line if you need some practical advise in this area.
Good Luck Tracy Dotson

I had a Ceramics instructor tell me once. "Unless you see a reduction
firing instruction included with a glaze formula feel reasonably safe
it's to be fired in oxidation." What do you think of this statement?
Would it make sense to use this guideline when submitting or reading a
formula here?

I'd say that's a safe bet if the glaze is anything up to (and maybe
including) cone 8. Unlabled cone 9-12 glazes are more likely to be reduction
or reduction/oxidation glazes in their usual usage.
ANY glaze can be fired in a variety of ways, but the results may vary
immensely. Some will be better, some worse, when fired at a different
temperature or type of firing. Experiment! The main caveat is with functional
ware for food use, where changing the parameters (firing temp, type, and
claybody) may make the glaze unsuitable or at least less desirable for such
ware, although this is not a given.

The problem would be that people on the list come and go. How would
someone new to the list know this? Isn't it easier just to say
Cone 6 Oxidation or cone 10 Reduction ?
Some people abbreviate and do ^6 ox. That's cool!
