The warming plate should always be preheated before use, preferably together with the crockery that will be used later (if possible). It is important that the surface is not exposed to excessive temperature differences, as this will damage the material. Therefore, please do not place very cold crockery on the hot glass plate or hot crockery on the cold glass plate.
