If your glaze has some clay but less than 10%, I would add 1% bentonite. This should be enough to keep your glaze suspended and prevent hard-panning. If you’re mixing a new glaze with little to no clay in it, you can add the bentonite to your recipe to start out with.
What are things to avoid doing when working with clay?

How do you prevent pottery silicosis?
Precautions Use lead-free glazes. Lead glazes should only be used on non-foodware items. If possible, don’t use colorants that are known human carcinogens and avoid probable human carcinogens. Consider wearing a respiratory when weighing and mixing powdered. Gloves should be worn while handling wet or dry glazes.
Are ceramics toxic?
If ceramics are baked for long enough at hot enough temperatures, they may still be safe, but if not, the lead can leach into food and cause lead poisoning. Acidic food or drink is especially likely to cause lead to leach out of ceramics, unfortunately for coffee drinkers with favorite earthenware mugs.

What does Epsom salts do in a glaze?
Epsom salt additions can be invaluable for glazes, its enables creating a thixotropic (gelled) slurry that applies evenly, holds in place and goes on in the right thickness on porous or dense bisque ware. When the slurry has a sympathetic specific gravity, about 2g per gallon of epsom salts should gel it.
What does bentonite do to a glaze?
Binder: Bentonite binds particles together in ceramic bodies to make them stronger in the green or dry state. Its minute particles fill voids between others to produce a more dense mass with more points of contact. Adding bentonite to glazes also imparts better dry strength and a harder and more durable surface.
