Here's the deal. I've been looking in all my 40 odd books and cannot find a
definitive answer as to whether to mix dry colorant into dry glaze mix. Or
can you mix dry colorant into a already mixed base glaze.
Thanks for any quick advice?

hi mary,
to get a good mix with an already mixed glaze one could take some of the
ready mixed glaze and put in the colorant, blend at high speed and then add
that to the rest of the glaze,. if no blender have to screen.

I add the colorant to my dry base, before I add the water. I dry mix the
whole thing too. You can easily control the percentages that way.
You can add dry colorant/stain to a pre-mixed glaze, but get the right
proportions of colorant would be tricky, and difficult at best to duplicate.
You would need to re-sieve the glaze after mixing and adding colorant.
Also, let it slake overnight and sieve again, just to make sure everything
is well mixed.

The answer is yes to both, with a small caveat.
Best to weigh out all materials dry, add to water, mix and sieve.
You can weigh out the colorant and add to the wet base glaze, but the
caveat, you need to know how much dry materials were used in the base mix so
you can add the proper percentage of colorant.
Yes, you can calculate the amount of material in the wet mix, but that
involves math....;-)

Mary,
You can do it either way, I usually do it while it's dry and I'm
weighing out the base glaze, but if you want to do it wet ,it's OK. I
use some of the base glaze watered down and sieve it several times then
mix into the base. Then I run it through a sieve again several times
before using. Mike Gordon

Both - but not definitively;-)
It is easier to judge the percentage by weight of colourant if you add to
dry ingredients as you don't have to take the water into account. It might
also be easier to get good dispersal - there have been some good recent post
about mixing dry.
Adding to a wet mixture means that it will probably have to be sieved a
number of times to get the colour to fully mix but if you are mixing tiny
amounts e.g. on a saucer for decoration you can judge by eye and
experience - a bit like water colour paint.

Yes Mary,
You can mix your stain with your base glaze, preferably in the dry state.

i mix mine in, wet or dry, with the small amount in the blender method (also
the only good way to test the % of colorants when you're testing colors
without completely losing your mind...)
