a) non-stick coatings don't last long, and most such cookware is pretty flimsy. Mind, there are better pans, like Henckels...but I use mine only for low-temp cooking, and with nylon or silicon utensils.
b) it may be the case that the coating breaks down at higher heat, and I know that concerns some
But these have a GABA cycle...which, reading, cooks at 104 degrees for 2 hours. Reportedly keeps an important amino acid more intact.
And induction cooking is much more efficient...but the downside is, you do need the metal mass. Not sure if that could work with doing a ceramic coating. BUT, if it's important to you, might I suggest you write them?
CraigLewisACK. My bad. GABA is a pre-cook method. Still, rice cookers, at least non-pressurized ones, should not be operating at the kinds of temps that might cause non-stick coatings to break down.
