Ok,Ok, Ok,
Let's say I have 1 cup of base glaze, already made up to the "glove"
consistency that I like. With this one cup I would like to add .5%, 1%
cobalt carb (ala mel & roger) and so and so on. Now, because the glaze is
already wet, let's say the 1 cup of wet glaze weighs 1 pound (16 oz). How
much cobalt (figuring the weight of the water in by actually subtracting it
from the 16oz's) do I add to my wet glaze? I believe there is a water
weight equation but I can't remember it. I think I figured out in a galaxy
far far away one time.
OR is there a rough % one can subtract from the normal dry weight percentage
of colorant you want to add to a glaze already wet? Yes, I know it all
depends on how much water you added to the glaze in the first place.
Anyone?
Thank you!
