I bet the original cement was litharge-glycerin. but I bet that's
illegal now, because litharge is lead oxide.


A good cement that isn't toxic is the old "pyro cement" of ages past.

White, hard as stone, and sticks to almost everything.

Calcium carbonate with enough sodium silicate added to make a thick syrup.


Never heard of pyro cement, though I had heard of various cements
involving sodium silicate. Some google fu yielded two things, one a
composition of shellac and black powder, used to stick fuses to
pyrotechnic star shells and the like, the other being one part zinc
oxide, one part calcium carbonate, and sufficient water glass (sodium
silicate) to make a slurry.

The key question will be resistance to dishwasher detergents,
especially phosphates and their phosphorus-free replacements.

I bet my old Handbook of Chemistry and Physics will have a formula or
two. But I bet they didn't consider dishwashers.
