How thin will clay still dry without cracking?

The thinnest I’ve made it is about 1/8-inch. It didn’t crack, but I wouldn’t go thinner than that.

How long does it take to fully dry? Can the clay part be added to something else by glueing it to another piece?

Mine was fully dry in 24 hours so guess it depends on what size chunk of clay you use. I made flat circles for my dogs paw print. Just let it dry slowly to not crack.

Does this crack or warp when it dries? I want to make watercolor palettes. What should I seal with so it can be used for a palette?

I seal it with Mod Podge dishwasher safe gloss. It’s on Amazon too. Haven’t had any trouble with warping or cracking using that. And it is waterproof.
