This accessory is necessary to stabilize round bottom woks on the gas stoves.
Not designed for woks over 16″ diameter.
Nickel plated steel. Can be used right side up or upside down depending on wok size and stove top surface.
I think that though this wok ring is adequate, that given the superb quality of the wok, the ring could have been more substantial. It seems light, and the wok slips on it a bit. This seems a design problem to solve. Perhaps there are reasons for this that I am not seeing, but a heavier ring that channels heat to the wok might be good.
