I'm reasonably sure non-stick ceramic pans are unsafe. They are certainly disposable, and misleadingly marketed. Also, the stuff under the coating should be cookware grade iron. It is fine if that leaches through. Why are they concerned about heavy metals leaching through? Is manufacturing leading to lead contamination or something?!?

There is an older technology that involves coating cast iron with actual ceramic. It is non-stick "enough", lasts generations and is safe. Example (high end) manufacturer:

A pure SiO2 (sand or glass?) non-stick coating seems like it would be reasonably safe.

But "made primarily from" gives me pause since they don't say what the other ingredients are.
