Thanks all for your comments and info. I did read (yes, I DO read, Lili),
however, several times that Gerstley Borate is no longer being mined. That
caused me to jump to an assumption that it was running out and would be hard
to get. That is what prompted my questions because I do have a lot of
recipes that call for it. I will keep all your good info; but, have been
told by a couple of clay companies that they have plenty on hand (??) And,
that they have good subs when the time comes. It's just more testing,
testing and testing.
Thanks

Hello Kathi,
Ferro frit #3211 was marketed as a Colemanite sub frit.
It is still available in Europe but not here anymore.

In the 70's there was a substitute for Colemanite (which was another
form of gerstley). The suppliers all said it was a good sub. I was
teaching at the the time and all of the cone 6 glazes I was using used
colemanite. Well, the subtitute was not just as good. The glaze actually
spit off of the pots during the firing. I would end up with little
droplets of glaze all around the pots.
It's my understanding that Laguna bought up all supplies fo Gerstley and
that other suppliers get it from then. I bought what I think will last
me until my career is over because I don't want to go through the
hassles of trying to make a substitute work. The same with Barnard clay.
I found a supplier in Canada and bought 50 lbs. I doubt that I will use
all of it. But any sub I've tried has just not given the look I want.
If you want to use glazes with gerstley I suggest you buy as large a
quantity as you can possibly afford. It will only get more expensive as
the supply dwindles.
