Angela, you're making this too complicated for yourself. You don't really
need to know the weight of the glaze in your wet sample. You just want
repeatable results.
This will be much easier if you do metric measurements. Jut take 100 ml of
wet glaze, which is a reasonable volume for a small test, and add colorant a
gram at a time to get the hue you want. Then it's really easy to adjust
both the volume of wet and the weight of dry to a large batch.

I have a bucket of transparent glaze already mixed up
and want to run some tests with stains and oxides.
I read recently that I could take a fixed amount of glaze,
say one yogurt cupfull , weigh it then subtract the weight
of the same amount of water. The difference would be
the weight of the dry ingredients in the glaze, allowing me to figure
the weight of stain to add.
I am wondering about the displacement of water by the glaze
ingredients, seems it would make a difference in the amount
of water in the container.
My question is......Will this work for my purposes?

Looking for lovely transparent glazes for relief tiles.

Thanks Paul,
I had been reading and thinking so much about this my
head was spinning. You are so right I just wanted repeatable
results.
I really appreciate your advice, I was sure someone was going
to tell me I had to measure out all those dry ingredients individually
for each test!

Can't wait to get testing!

Thanks Paul. How exactly do I go from the results of a sample made from
100ml of glaze to a 1000gm dry batch while keeping the exact same
colorant proportion? Is there a formula?
