GLASS AND GLASS-CERAMIC
Heat-resistant glassware is very 
suitable. You can observe the 
cooking process from all sides. 
It cannot contain any metal (e.g. 
lead crystal) or a metal coating (e.g. 
gold frame, china blue).
CERAMIC
In general, ceramic is very suitable. 
Ceramic must be glazed because 
moisture can penetrated the ceramic 
if it is unglazed. In a microwave 
oven, this moisture will heat up and 
can cause the ceramic to shatter. If 
you are not sure whether your cookware is suitable for 
use in a microwave, please do a suitability test. See Page
GB-32.
PORCELAIN
In general, porcelain is very suitable. Be sure that your 
porcelain does not contain any metal or gold or silver 
plating.
PLASTIC
Heat resistant, microwave-safe 
plastic ware is suitable for thawing, 
heating and cooking. Please note 
the manufacturer’s instructions.
PAPER DISHWARE
Heat resistant, microwave-safe paper dishware is also 
suitable. Please note the manufacturer’s instructions.
PAPER TOWELS
can be used to absorb excess 
moisture in short heating processes, 
e.g. for bread or breaded items. Put 
the paper towel between the food 
and the turning plate. The surface of 
your food will stay dry and crunchy. 
Covering the food with paper towels 
will contain splatters from greasy foods.
MICROWAVE FOIL
or heat resistant foil is suitable for covering or wrapping 
foods. Please note the manufacturer’s instructions.
ROASTING BAGS
can be used in the microwave oven. Metal clips are 
not suited to close such bags, as 
they might cause the foil to melt. 
Use kitchen string to close these 
bags and pierce the bag with a 
fork. Do not use foils that are not 
heat resistant, e.g. cling film, in your 
microwave.
METAL
should not be used, because the microwaves cannot 
penetrate it and can therefore 
not reach your foods. There are 
some exceptions: Narrow strips of 
aluminum foil can be used to cover 
parts of food, so that these parts do 
not thaw or cook too fast (e.g. the 
wings of a chicken).
Small metal spikes and aluminum bowls (e.g. in ready-
to-serve meals) can be used.
They must be small in relation to the food, e.g. the food 
must fill the aluminum bowl at least 
 to ¾. We recommend transferring 
such foods to dishes suitable for 
use in a microwave. When using 
aluminum bowls or other metal 
dishes, you must keep a minimum 
distance of about 2.0 cm to the 
walls of the cooking chamber, otherwise they can be 
damaged by possible sparks.
DO NOT USE DISHES WITH METAL PLATING, 
or metal parts, e.g. screws, bands or handles.
