letting newly mixed glazes "steep" for a day?

If it's a shino using soda ash, it's good to give the mix some time to allo=
w
the bubbles to break up, like overnight. Otherwise, there's no reason why
you can't mix a glaze and use it. Been doing it for 3 1/2 decades with no
problems at all.

What I've noticed is some of my newly mixed glazes are sort of frothy.
Letting them sit for a day settles the bubbles a bit.

Lots of good replies here as expected. One thing that I assumed
someone else would talk about is sieving. You definitely need to let
the glaze sit for an hour or so before sieving.

Since I make 4 gallons or so of glaze at a time I have bought myself
one of those large Talisman sieves with 3 brushes on a crank. They
really do work like a charm. If I want bubble-less, well wetted glaze
the same day, I just put it through the sieve (100 mesh) twice. That
seems to do the trick.

I like to soak my glaze for 24 hours before i mix it. There are less
bubbles that way. If I were to sieve that day, i would blend it with a
hand blender the moment I walk in the studio. Then I go back and blend
it every now and then while I do other chores. I try to glaze my wares
at the end of the day and let my glaze sit a little bit and try not to
rush. I don't get frothy glaze slope anymore. Veegum seems to help the
bubbling too (just a bit, if I splash around with the buckets and try
to rush to load the kiln so that I can be home before mid-night, but I
always regret it when I open the kiln)

I weigh out all glaze for the density, so I don't need to worry about
the consistency. It used to really screw me up with wrong glaze
application thickness.

I found that having extra buckets of soaking glaze materials helps the
production work flow. I spend half boring day weighing out glazes and
I am good for many months.

Sorry, more than what you need to know and asked for.

Hmmm,
Maybe it depends on the glaze, I know if i don't let my base glaze
steep overnight it is just wrong with many problems.
because of that, i let them all rest.
I think it allows the powders to absorb the water compleatly..

P.S. With ash glazes, done the traditional way, you have to prepare
your woodash 3 firings ahead of time. You do test tiles first.
Make adjustments according to the test. Do another set of test tiles.
Adjust if you have to. Then fire a pot with the new glaze on it.
The 4th firing, you usually can use it normally.

You just have to plan ahead.

I am preparing a garbage can full of wood ash. (will wash it about 3
times.) I will wet mix it with kaolin slurry and dolomite slurry to
make my standard ash glaze. I am subbing dolomite for amakusa
porcelain stone. Cornwall Stone might be another good substitution.

Jennifer Boyer raises another problem, that of frothing.
There is no doubt that stray bubbles adhering to a freshly dipped pot can
cause blemishes that are unwelcome on the surface of a finished pot.
One way to settle and eliminate surface froth from a liquid glaze patch is
to spritz affected glaze with denatured alcohol, sometimes known as Metho o=
r
Meths. This seems to reduce surface tension causing bubbles burst.
