>Of course, one issue would be whether or not it was food grade talcum powder.

I figured that seeing it is sold for dusting on babies that it has been researched fairly extensively.

I also know that it is found in association with asbestos in rock, so wonder about that.

Would it migrate into the frames?  I doubt it, since it is a solid and quite inert AFAIK.

Talcum power comes in a handy disposable bee-blaster which can even be recycled.
