• Never use equipment made of metal, except aluminium
foil in your microwave. The microwave energy cannot pass
through metal so it bounces off and sparks against the
inside of the microwave.
• Stop the microwave straight away if any equipment is
causing sparks.
• Remember that some crockery has a metal trim around
the edge. Even this trim can cause sparks.
Containers
Warning : Pressure will build up in sealed containers and
can cause them to explode. Therefore, do not use the
following in your microwave:
- Sealed containers
- Capped bottles
- Vacuum containers
- Sealed jars
- Hard-boiled eggs
- Eggs in their shells
• Always pierce the skin of fruit and vegetables, such as
potatoes.
• Never use scratched, cracked or damaged glass in a
microwave. Damaged glass can explode.
• Caution should be used when using combustible
containers, never leave the microwave unattended when
in use.
Delayed Boiling
Liquids heated in a microwave continue to cook after the
cooking time has elapsed. Caution is to be used when
removing hot liquids from the microwave.
Take the following precautions:
• Always stir liquids, before and after cooking.
• Allow them to stand.
• Use containers that are wider at the top than at the
bottom.
