Schott invented the heat resistant Halogen Cooktop
Schott, a German glass manufacturer, was formerly a glass-to-ceramics company for use in space telescopes. In 1983, the company announced the invention of a halogen cooktop, called CERAN, made from a glass-ceramic material.
Although halogen lamps, which can give extremely high amounts of heat and are durable for a long time, are a very suitable product, especially for cooking, the use of this product in the kitchen was not very common due to the low number of products compatible with it. CERAN introduced the power of halogen lamps to chefs around the world. Thanks to the reflective partitions in the halogen stove, the heat from the lamp was reflected on the surface of the stove.
Light bulbs and similar products used in daily life contain a tungsten filament in a glass inflated with inert gases such as argon. Although halogen lamps work with a similar method, halogen gas, which is usually iodine or bromine, is used instead of inert gas. The use of this type of gas provides the reflection of the heat as well as the light produced by the lamp by increasing it in a high amount. However, it also requires the use of stoves specially developed for these lamps. This halogen cooking surface, called CERAN, is translucent and has a stable heat rate, and is extremely resistant to heat.
Although the halogen hob offers a flat cooking surface, there were also hobs with flat cooking surfaces long before CERAN. Thanks to the electric coils placed at the bottom of the glass-ceramic hobs, hobs with a flat surface took their place in the kitchens; however, these stoves were not resistant to the high heat produced by halogen lamps. Schott's CERAN halogen stove became extremely popular in a short time after it was produced, selling over 50 million copies, and is a part of many manufacturers' halogen stove products.
