Metallic containers for food and beverages are not allowed during microwave cooking. This requirement
is not applicable if the manufacturer specifies size and shape of metallic containers suitable for
microwave cooking.

8. Do not use recycled paper products when microwave cooking, as they may contain small metal
fragments which may cause sparks and/or fires.
9. Round /oval dishes rather than square/oblong ones are recommend, as food in corners tends to
overcook.

don't use too much and keep a distance of 1 inch (2.54cm) between foil and cavity.
