Skeptical chez is skeptical.
I saw this happen on a ceramic top stove that was probably 12-15 years old...I thought it was induction, might not have been...they left it on the burner on high...and the cast iron skillet was stuck to the top.
Well this is what Lodge says about their current product:
We get asked a lot about using cast-iron cooking vessels on the ceramic-glass surface that all induction-cooking units use: does it scratch? Can one cook using "pan-slide" techniques without scratching the surface? Lodge cautions that their non-enamel cast-iron cookware (and this would likely apply to all cast-iron cookware except, of course, enamelled cast iron) might cause scratching, as the bottom of a cast-iron piece is naturally rougher or grittier than, say, stainless steel, and anecdotal evidence strongly supports the realistic possibility of such scratching. But . . . this is induction--no flames! We thus need to think outside the box. If you have a cast-iron skillet and want to cook something using the pan-slide method, just put a sheet of some heat-resistant (and non-metallic) substance under it. The obvious choice is parchment paper; though one maker (Reynolds) says it can be used "at temperatures up to 420°F", Cook's Illustrated refers to its being "enormously resistant to high temperatures"; many widely published recipes using parchment paper call for baking at 450°F and we've even seen pizza recipes calling for parchment paper in an over at 500°F to 550°F. All in all, it seems unlikely that the temperature of a skillet bottom would be a problem for parchment paper (and its silicon coating makes it slick and so, presumably, easy to slide a pan on). While we haven't yet had opportunity to test it ourselves, we feel confident it would work fine in this use. Parchment paper is relatively inexpensive--only a tad more than ordinary waxed paper--and universally available (and is a handy thing to have in a kitchen anyway); Cook's likes the Reynolds brand.
(The "autoignition temperature" of a substance is the lowest temperature at which it will spontaneously combust in a normal atmosphere without an external source of ignition, such as a flame. The autoignition temperature of even ordinary paper is 451°F (233°C)--as is well known from the title of the famous Ray Bradbury novel Fahrenheit 451--so parchment paper ought to fill the bill here just fine.)
There is also an almost comically simple alternative for a more permanent fix. It's one of those ideas like the safety pin or the paper clip: blindingly obvious in hindsight, but not apparent at once. Just sandpaper the pan or pot bottom smooth! Readers have reported to us that they have done just that, with excellent results. We don't have details, but we'd guess that two grades of sandpaper, a coarse then a fine for polishing off, would do the job. (If you've done this, please email us with exactly how you did it.)
