Suitable cookware for microwave ovens
Microwaves
– are reflected by metal,
–pass through glass, porcelain, plastic and cardboard,
– and are absorbed by food.
,Fire hazard! Containers that are not microwave safe can be destroyed and may damage the microwave oven.
Material and shape
The material and shape of the container used affect the reheating and cooking time. Flat containers with a circular or oval shape generally work best, since the food will heat more evenly than in square or rectangular containers.
Cookware with hollow knobs or handles in which moisture can accumulate is not suitable for use in microwave ovens, except when these hollow recesses are sufficiently ventilated.
Otherwise, there is a danger of a pressure buildup, which may cause the recesses to explode. Risk of injury!
Metal
Metal containers, aluminum foil, metal utensils, and dishware containing metal (decoration such as gold rims or cobalt blue) must not be used in the microwave oven. Metal reflects microwaves and thus hinders the cooking process.
Avoid using plastic containers where the aluminum lid has not been completely removed.
