Practical advices
∙Use heat resistant ovenware made of glass, glass, ceramic, and porcelain, ceramic or
∙This is not the case with ovenware made of metal. The microwaves are obstructed which means that the food in closed containers remains cold. Ensure that any metal objects – e.g. a spoon – are at least 2 cm away from the oven walls and the inside of the door. The glass on the inside of the door could be damaged by sparks.
∙To cook or defrost pieces of meat of irregular sizes, you may cover the thinner parts with tin foil, which should be kept at least 2 cm away from the oven walls, otherwise these may cause an electric arc.
∙Metal spits may be used as long as they are smaller than the pieces of meat.
∙Crystal contains a percentage of lead, which may cause it to crack if used in the microwave oven. The same may happen to glass dishes with jagged edges.
!Porcelain dishes may be used but they should not have hollow handles. Humidity may be formed inside the hollow handles, which will causes an increase in pressure that may cause them to break.

!This type of dish may heat considerably.
Painted glazed ceramic dishes may be used if the painting is done under the glaze.
Many glazes and colours contain metallic substances. If this is the case they should not be used in the microwave as they may be damaged.
Recipients with silver and gold glazes may go dark.
!Plastic dishes should be heat resistant (at least 180° C) or they may be deformed when used in the microwave. Melamine dishes are not suitable for use in the microwave as they heat up too much
To cook or heat food in plastic bags, they should be perforated to allow vapour to escape thus preventing the bag from bursting.
!Wooden recipients should not be used in the microwave. Wood contains water, which evaporates and may cause the recipient to crack.
