Modern, aesthetic, easy to clean… the glass-ceramic top cooks seduce by their cleaned look and their practicality. But behind this design asset is hidden that many underestimated. A simple mistake, however common, may be enough to crack it. Here’s everything you need to know to avoid this costly disaster.
What mistakes should be avoided?
A vacuum heat trap
When you place a hot lid flat on a glass-ceramic plate, an unexpected phenomenon occurs. The heat trapped between the cover and the plate creates a suction effect, comparable to a vacuum seal. This additional pressure weakens the glass, especially when it starts to cool.
The result is an unpredictable break-up
The pressure caused by this seal, combined with the temperature difference between the heated and cooled areas, can cause cracks in the shape of a spider web. Not only do these cracks ruin the aesthetics of your plate, but they also endanger your safety.
