celain, pottery, glazed earthenware and bone china are usually
suitable, except for those with metallic decoration.

heated suddenly.
Metal ✘ It is not recommended to use metal cookware when using micro-
wave power as it will arc, which can lead to fire.
Plastic / polystyrene ✔ Care must be taken as some containers warp, melt or discolour at
e.g. fast food containers high temperatures.
Cling film ✔ Should not touch the food and must be pierced to let the steam
escape.
Freezer / roasting bags ✔ Must be pierced to let steam escape. Ensure bags are suitable for
microwave use. Do not use plastic or metal ties, as they may melt or
