In a school situation we don't dry mix anything, for health's sake.
Even if the person mixing wears a mask, the dust put into the air doesn't
fall out for a long time.
So how do we handle bentonite in a glaze?
Because it is usually the last ingredient in the recipe and sits on top of the
rest of the materials in a bucket, it is easy to very briefly stir just the top 1/2
inch with your hand to mix the bentonite particles with whatever is below .
That is all it takes, a few seconds.
Tip. You know how the glaze makes dust when the water is added, also
putting stuff into the air? If you put a sieve on top of the bucket--the plastic
edged kind that fits the bucket like an indented lid--and put the water
through the sieve and leave the sieve in place while the glaze absorbs the
water, no dust can come out.

This is a little absolute. If you use the dry-mixing system with the
cardboard drum, as I described, there is not dust at all, because the drum
is sealed.

Good Morning Vince:
I am not suggesting that anyone else do it my way. I am just reporting
what we do here. Flexible is my middle name. Suggestions aren't
absolute, they are just suggestions--take it or leave it.
I once mixed clay in a cardboard drum when I had no mixer. It was
necessary then. I don't find it necessary now and, like Mel, have never
found it necessary to dry mix a glaze, ever. We even do 50/50 glaze
blends wet to avoid the dust. AND it is much faster.
