• Never use equipment made of metal, except
aluminium foil in your microwave. The microwave
energy cannot pass through the 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.
