SimmerMat is made from high-quality zero-carbon steel. It has 12 strategically-placed cones, which transmit heat evenly to the base of the pot so the food inside won't catch and burn when used on any cooking surface. See our how to use page for instructions on using the SimmerMat on different cooking surfaces.

SimmerMat is finished in either black enamel or dark blue pyrolytic enamel, which not only look good in the kitchen for many years but can also withstand moderate heat.
The round SimmerMat is 210mm (8 inches) in diameter and the octagonal one 200mm (7.8 inches).
SimmerMat works on every type of gas cooking appliance and also on electric elements, solid fuel burners, and all commercial stoves.
