Induction cookware is starting to become part of more and more homes. So it is important to know recommend utensils for good use. Traditionally flame or heat transfer resistors are use for pots and pans. But a glass-ceramic stove works differently. In this case one is create electromagnetic field producing heat in metal of pot. So that this is need a spatial material that reacts to this energy. Ideally, either iron (at least in base), as aluminum cookware, ceramic or glass do not work with electromagnetic field.
To find out if it is appropriate, all you have to do is to bring a magnet to pot. So that if there is attraction and it attaches. Then you are in front of correct material. In market you will find different types of pans for induction cookware. But unfortunately not all are of adequate quality and because it is a relatively new technology, many customers do not know how to choose.
First thing you have to keep in mind is size of base. Induction cookware must have same diameter as rest of pot, so that display an almost cubic shape. Reason is that energy is generated at base, so if it is less in its diameter to walls, then it will not transmit heat efficiently. On other hand, it is also ideal that surface is uniform. Rugged designs prevent contact with plate, which generates noise and more cooking time.
