Selecting cookware
Microwaves:
– are reflected by metal,
– pass through glass and chinaware,
– are absorbed by the food.
Material and shape
The material and shape of containers used affect cooking results and times. Circular and oval containers work best. The food will heat more evenly than in a square container.
Container and lids which contain hollow handles or knobs are not suitable for use in the microwave. The handles or knobs could collect moisture if not adequately vented. Without vent holes pressure can build up, causing the container to crack or shatter, danger of injury.
Metal
Do not use metal containers, aluminum foil, cutlery or dishes with metal decor in the microwave.
The metal reflects the microwaves which can damage the microwave.
