Though glass and pottery are both ceramics so I believe there is a chemical/material bond as well that doesn't take a primer. But you also have things like porcelain sink that is ceramic on metal, and even porcelain metal cookware that are too and would defy your statement of inert on metal == bad automatically.
Some metals have a self oxidized coating that is inert and stuck on, for example titanium cookware used in hiking.

Anyway, with how gentle you need to treat those pans I don't think they're worth it, even if safe. Stainless or cast iron aren't hard to clean and are essentially idiot proof, so that's what I like to use.
