Ovenproof Glass: Glassware that is heat-resistant is microwave-safe. This would include all brands of oven tempered glass utensils. However, do not use delicate glassware, such as tumblers or wine glasses, as these might shatter as the food warms.
Pottery Stoneware Ceramic: Use bowls, cups, serving plates, pottery, stoneware, ceramic, and platters without metallic rim. Many containers made of these materials are microwave-safe, but test them before use.
Plastic
Plastic Storage Containers: These can be used to hold foods that are to be quickly reheated. However, they should not be used to hold foods that will need considerable time in the oven as hot foods will eventually warp or melt plastic containers.
Plastic Cooking Bags: Provided they are specially made for cooking, cooking bags are microwave safe. Remember to make a slit in the bag so that steam can escape. Never use ordinary plastic bags for cooking in the microwave oven, as they will melt and rupture.
Plastic Microwave Utensils: A variety of shapes and sizes of microwave utensils are available. You may be able to use items you already have on hand rather than investing in new kitchen equipment.
Paper: Use paper towels, waxed paper, paper napkins, and paper plates with no metallic rim or design. Paper plates and containers are convenient and safe to use in the microwave oven, provided that the cooking time is short and foods to be cooked are low in fat and moisture. Paper towels are also very useful for wrapping foods and for lining baking trays in which greasy foods such as bacon are cooked. In general, avoid coloured paper products as the color may run. Some recycled paper products may contain impurities which could cause arcing or fires when used in the microwave.
Tableware: Many containers made of pottery, stoneware and ceramic are also microwave-safe. If in doubt consult the manufacturer’s literature or perform the microwave test. Do not put plates with painted decoration in the oven, as the paint may contain metal and cause arcing.
