The thing is that the thermal glassware is made of special glass – it is called borosilicate. In fact, it is a material with completely different characteristics than ordinary glass. Until recently, it was used only for laboratory glassware and for complex medical devices. Now, borosilicate glass is actively mastered by manufacturers of dishes and here on the shelves began to appear glass goblets, mugs and glasses, bowls, which in appearance are very similar to ordinary ones, but in reality – completely different.

This dishwasher easily withstands thermal shock – abrupt heating, abrupt cooling – all of these objects do not care. This dishware is not afraid of washing in a dishwasher – it does not get cloudy or scratched.

Another fact – from the category of shocking – such dishes can be put in the oven. Why would it be needed? Well look. They put a green apple in the glass, a summer cottage Antonovka, for example. Poured with honey, sprinkled with cinnamon, put in the oven. And then, right from there, without shifting to any other container, they were served directly in a beautiful glass glass to the table. Or portioned curd dessert. Cottage cheese was mixed with protein, put in a glass bowl, baked, decorated with berries and now look, what a beauty it turns out!

Thermal cookware is remarkable for another property. It keeps the temperature of food and drinks. Thermal dishes have double walls, like a thermos. Therefore, the hot in them cools slowly, but the cold does not become warm. This is especially valuable for mugs, cups and glasses. Poured tea into such a mug and it will be hot for about fifteen minutes. Poured a cold cocktail with ice into the glass – you can be sure that it will not heat up for a long time.

Despite the double layer of glass, such dishes are incredibly light because its walls are thin. Another shock fact is thin glass, despite the apparent fragility and weightlessness, durable. His density 2.23g / cm
