Ceramic, glass, or plastic containers are best for cooking with microwave oven. Make sure that any plastic containers are made specifically for microwave oven use; if not, they may melt. Also, use dishes that contain not traces of metal, including the trim and handles. If using plastic wrap or paper towels, be sure that they are clearly labeled as safe to use in a microwave oven.
Avoid using the following containers in a microwave oven: polystyrene (such as foam coffee cups and take-out dishes); glass bottles; cans; metal pots (or anything metal, for that matter); wooden bowls; mugs or ceramic ware with glued-on handles; and plastic storage containers that are not specifically intended for microwave use.
