Adding Bentonite to a Glaze That's Already Wet. If I need to add bentonite to a glaze after it's been mixed (to fix a hard-panning issue, for example) I just weigh out the bentonite (usually 1% of dry glaze weight), sprinkle it into a small amount of water, and wait for it to slake down. You want enough water to fully cover the bentonite.
