UTENSIL GUIDE
Only use utensils that are suitable for use in microwave ovens.

or absorbed by the dish used. Care must therefore be taken choosing the utensil. If the utensil is marked
microwave-safe, you do not need to worry. The following table lists various utensil and indicates whether and
how they should be used in a microwave oven.
