User Manual Aroma AEW-306 Electric Wok with Tempered Glass Lid Easy Clean Nonstick

The coating is like Teflon. I only used this twice however because the electric control is very loose where it fits into the wok plus the temperature control is erratic and difficult to set. In the "OFF" position mine was still "ON" and hot.

It had low-high settings on it but as mentioned in my scathing review, it became defective after only a few uses and had only two settings: scorching high and off.

The wire rack clips on the outer edge of the wok "skillet" - you an place veggies or meats on the rack and drizzle or brush your choice of sauce on the bits of food -- the steam from the food cooking below in the bottom of the wok will steam the food on the racks.

Thank you for contacting Aroma Housewares. The diameter of the pot without the handles would be 14.3".

Best answer I would have is -- low, medium, high ... similar to a electric fry pan. Low approx. 100 degrees / medium approx. 250 degrees / high approx. 380 degrees
I hope this helps.
