I’ve read this article this afternoon and it kinda hit me with some negative feelings towards BB, always being a bit more thorough with their claims (which I usually find informing)…
Anyway, I work at GreenPan and while this can be a bit of a bias, I know, these words are my own as the subject really interests me. GreenPan actually launched the ceramic non-stick coatings some years ago. The basic ingredient of the coating is Silicon Dioxide (Silicon, not silicone) which is basically a kind of sand, also used for glassware etc. It is indeed completely free of chemicals that could be dangerous, even when overheated.
There is a small difference in use as ceramic non-stick pans distributes heat more efficiently so people tend to burn their food and oils and damaging the pan using too high heat. This is because they are used to “traditional” non-stick pans of which the plastic-based coatings block the heat somehow. But if you keep an eye out not to overheat them, they are equally convenient and durable.
It’s refreshing to find someone actually helps to inform the people on the true nature of PTFE pans and of ceramic non-stick wannabees.
