hi group
there has been a lot of info about dealing with frozen glaze. my
problem is a little different. most of my glazes have dehydrated over
the last year. what do I do to reconstitute them properly. my logic
tells me to break the glaze into powder with a hammer, (Mask on of
course) dump water in, get my trusty drill with the jiffy mix
attatchment, mix and sieve. but has anything been so changed by being
liquid, then dried, and then liquid that there will be a problem. I
hate to have to pitch this stuff and re mix. but I don't want to have a
worse problem if I use it and and then have failed glazes. it is all ^6
ox glazes.
thanks

I don't think it is necessary to take a hammer to the glazes. They will
dissolve readily when water is added. We have always just added
water to dehydrated glazes to reconstitute, and mixed, sieved. Not
had any problems with them, they seem the same. All of our glazes
are ^10, reduction; I doubt that matters. Maybe Ron Roy or Tom Buck
or Craig Martell etc. will have another view.

Millie -- Save yourself a lot of work and just leave out the hammer
stage. Take the old dried glazes and add water. Wait a day.
That's it.
The only difference really between the original starting dry mix and
the dried out mix is how fluffy it is! It is fun to hear the glaze
"sing" when the water hits it. I know people who sound that way
when the first slug of cold beer hits the throat on a hot hot day.
If you use hot water, it will slake faster. (That's the technical
term -- "slake". that's what it is doing while you read a magazine
or whatever.)
I always use distilled water and especially would do so for this
job. The old water that evaporated has already left its various
salts in your glaze. in order not to concentrate those anymore, use
water that doesn't have anything in it except the H2 and the O.
That's distilled water; most of the big pharmacies carry it in
gallon jugs.
Then, how much water? Weigh your dry glaze buckets (subtract out
the weight for the bucket itself assuming you have an empty one) and
use about the same weight of water as you have of dried out glaze.
That just saves time in getting it ready to use. so it doesn't have
to settle and so on.
Sieve it of course.
Enjoy,

never had problem with dried out glazes. Add plenty of warm water (NOT
BOILING) let sit a few days stir, sieve, test. I cannot imagine what
would have made a dried out glaze deteriorate but testing always the safe
route.
