This frying pan is truly a revolutionary breakthrough in non-stick cookware. The stone-like marble coating not only makes this wok as tough as stone, enabling it to withstand as much as 10X more abrasion as a standard teflon coated cookware; this special marble coating also makes this wok totally non-stick and non-scorching. Absolutely no oil needed to fry/grill your favorite food. And cleaning, you'll be amazed at how easy it is to clean this wok...just a dash of dish soap and a soft pad, absolutely no scrubbing with powder abrasives, hard pads etc. Plus with the marble coating on both inside and outside, your wok will continue to look like its new forever, even from the outside.
