Claim: “Unaffected by temperatures up to 850˚F/455˚C”.
Fact: Not only false but irrelevant.
While the ceramic part of the coating can withstand this temperature, the silicone fluid (that provides the nonstick characteristic) cannot.
It decomposes at around 600˚F/ 315˚C, leaving the ceramic surface with the nonstick characteristics of a dirty dinner plate.
The silicone fluid is also removed by washing in the dishwasher.
