We recently replaced out old induction top with a new Bosch indo unit.
Tonight did wok stir fry and put a 12"x12" silpat oven liner beneath the wok to prevent scratching the cook top. (Yes, our steel round bottom wok will couple with the new, and old indo tops)
After heating up, the silpat melted some what at the point of contact and stuck to the wok bottom. No big deal, but it indicates the point of contact was at least over 480*, the advertised capability of silpat!
