Beyond the problem of toxicity, it should be noted that this coating is not stronger than a PTFE coating and requires the same precautions for use and maintenance.
Our own experiences prove that it is very vulnerable to overheating even if it seems that notable progress has been made over the last generations. So don’t expect that a ceramic pan lasts much longer than a PTFE-based pan.
But on the other hand, the ceramic pan can be recycled much more easily. In conclusion, given the lack of perspective and the little information available, it is, therefore, necessary to be careful even if some elements suggest that a ceramic coating is a little healthier than a PTFE-based coating.
This coating is sand derived. It can therefore be considered healthier. The manufacturers ceramic coating ensure that their product does not produce toxic fumes in case of overheating and that the application of coating on metal does not require glue.
The use of chemicals would be therefore reduced. But there is not much more information on the exact composition of this coating. And to date, there are no serious scientific studies that have evaluated its harmfulness in the long term.
