The heat diffuser distributes heat uniformly and consistently, eliminating burning and sticking of foods to your pan. Whenever your pan gets too hot, place the diffuser between the heat source and the pan to lessen the intensity of the flame on your gas burner. Made of enameled cast iron, the heat diffuser also prevents the blackening on the bottom of the pan associated with flames on gas stoves. Suitable for all types of pots and pans, the heat diffuser is 7" in diameter. A removable handle that fits into the side of the diffuser makes it easy to move the diffuser between burners when it's hot. Boxed.
