Always make sure some load

Always make sure that you operate your oven with some load in it. This means that you need to put some food or water in the cavity provided while using it. Check what instructions are provided by your manufacturer. If your dishes (serving bowls, plates, mugs, cups, etc.) contain any lead at all, leaching of lead into your food is accelerated in a microwave. Utilize glass such as Pyrex or Corningware to cook food (and even to heat food, especially greasy, sugary or acid foods) whenever possible for greater safety and peace of mind.
