China and earthenware	√	Porcelain, pottery, glazed earthenware and bone china are usually suitable, unless deco-rated with a metal trim.
Disposable polyester cardboard dishes	√	Some frozen foods are packaged in these dishes.
Fast-food packaging
Polystyrene cups containers	√	Can be used to warm food. Overheating may cause the polystyrene to molt.
Paper bags or newspaper	✗	May catch fire.
Recycled paper or metal trims	✗	May cause arcing.
Glassware
Oven-to-tabeware	√	Can be used, unless decorated with a metal trim.
Fine glassware	√	Can be used to warm foods or liquids.Dolicate glass may break or crack if heated suddenly.
Glass jars	√	Must remove the lid. Suitsole for warming only.
