Hey there ClayFolk!
Got a question for you...
I want to test about 10 different colorant combos in the same raku base
glaze.
I'd like to make a large batch of the dry base glaze (say 1,000 grams
for instance) and then divide it into 10 small portions of (for
instance) 100 grams each and then add the colorants to the smaller portions=
.
One side of my brain says this is perfectly logical, but the other is
saying that getting all the dry ingredients in the base glaze uniformly
mixed is unlikely, and therefore this won't work.
So, I thought I'd throw that out there.
I'm guessing some of you can give me some insight into whether this
would work?
thanks!

No problem, put the 1,000 gram batch into a sealable plastic container, giv=
e
a good shake up, making sure lid is securely fastened. Wait, as they say,
until the dust settles, then dry sieve batch through whatever you sieve you=
r
wet glazes through, such as 30m & 60m screens. Then weigh out your 100 gram
batches. Don't be surprised if your last batch is a few grams short...

It is perfectly logical, except that you add the water to the proper
consistency, sieve it, and then divide it. Clear plastic cups make it
easy to see that you have 10 equal amounts.

When I was in school we would make up a large batch of a base glaze, say =
=3D
10,000 grams (that seemed a lot of glaze at that time). We would then =3D
divide it equally into ten containers and add colorants to each =3D
container. It works if all of your smaller containers are identical and =3D
you can see through them so that each has the same amount of base.=3D20

Paul, before I got a good digital scale, I often dry mixed that amount of d=
ry base glaze in a large mortar, then weighed out the individual batches wi=
th the added oxides.
Regards
June

This works very well indeed. Just mix the full
batch well. Never had trouble with this method.
