SCHOTT introduced the first glass-ceramic cooktop panels to the market in 1971 and has since sold them under the registered trademark CERAN®. Only the original glass-ceramic cooktop panels from SCHOTT are allowed to bear the CERAN® brand name.
CERAN® is a registered trademark of SCHOTT AG. It stands for special values: quality and functionality, technological and design innovations, social responsibility, and sustainability.
CERAN® is the brand name for the material developed by SCHOTT in 1971: A material that combines the aesthetics of glass with enormous heat resistance and stability. Quartz sand is the most important raw material in the manufacture of glass-ceramic.
This is a material that can withstand extremely high temperatures thanks to extremely low thermal expansion (close to zero), making it optimally suited as a stove surface. The brand name for the material developed by SCHOTT in 1971 is CERAN®.
SCHOTT CERAN® cooking surfaces consist of patented glass-ceramics – a material that combines the aesthetics of glass with enormous heat resistance and stability. Quartz sand is the most important raw material in the manufacture of glass-ceramic. This is available in almost unlimited quantities. The so-called ceramization process then converts the glass finally into glass-ceramic.

CERAN® is the brand name for SCHOTT AG’s glass-ceramic cooking surface. This can be combined with all heating technologies, i.e. radiant heat, gas, and induction.
SCHOTT CERAN® is the world’s first black glass-ceramic to be manufactured in an environmentally friendly manner – i.e. without the use of the toxic heavy metals arsenic and antimony in the production process. This is made possible by a specially developed melting technique. This protects people’s health in the same way as it does nature. SCHOTT CERAN® glass-ceramic is also fully recyclable.
SCHOTT CERAN® is very resilient – the normal thermal and physical stresses in everyday kitchen life have no influence on the stability of the glass-ceramic cooktop panels.
SCHOTT CERAN® is particularly temperature-stable – the material can also withstand abrupt thermal shocks in the range from minus temperatures to plus 700°C.
SCHOTT CERAN® is energy-efficient – the cooking surface, which is only 4 mm thick, is very heat-permeable. The heating energy reaches the cookware with almost no heat loss. Also, relatively little heat escapes at the sides (low heat transmission).
SCHOTT CERAN® is safe – due to the low lateral heat conduction, only the cooking zones become hot while the remaining surface remains relatively cool.
This depends entirely on your individual wishes. SCHOTT CERAN® is suitable for all heating technologies – from electric radiation to gas and induction. As long as SCHOTT CERAN® is installed in the kitchen appliance, you are ensured the highest quality and durability.
An autonomous cooktop is detached from the oven, which is often installed underneath cooktops. The self-sufficient cooktop has its own power supply and controls.
The function depends on the selected heating system:
The smooth surface of glass-ceramic makes it particularly easy to clean. The operation of the cooktop is also important.
The transparency of the glass-ceramic as well as its electrical properties enable the use of displays and touch switches (touch control) in state-of-the-art cooktops. Perfect for modern kitchens.
SCHOTT CERAN® can be combined with all the common heating technologies – whether you choose a stove with radiant, induction, or gas is a matter of preference and budget. If the corresponding connections are available, different heating technologies can be combined in a kitchen without any problems.
Induction cooking produces heat in the base of the magnetic pot or pan. The cooking surface itself remains relatively cool, there are no red-hot cooking zones. The technical principle: A coil with current flowing under the cooking surface generates an electromagnetic field. This causes eddy currents to flow to the bottom of special cookware made of ferromagnetic material, which heat the metal of the pot. The pot transfers the heat up to the food. Nothing happens on the glass-ceramic cooktop panel without a pot. With a pot on top of the cooking zone, temperatures of up to 350°C can be achieved under the pot, depending on the food and cooking process. In the event of improper operation, such as an empty (forgotten) pot, significantly higher temperatures of more than 500°C can be achieved.
In general, induction cooking is switched on and off quite quickly. The boiling time is particularly short, the reaction time is extremely fast, and the heat input can be dosed very precisely, since the heat enters the pot directly. If you remove the pot from the cooking surface, the heat supply immediately stops – this is not only safe but saves a lot of energy, too. You can also conveniently clean an induction cooktop featuring a SCHOTT CERAN® cooking surface. Food residues are less inclined to become burnt on, thanks to the moderately heated glass-ceramic surface.
This depends on the cooking technology. SCHOTT CERAN® effortlessly withstands the temperature differences in the kitchen. Temperatures of up to 700°C are no problem.
No. Only the areas above the heating elements, the cooking zones, are heated. The surrounding area, as well as work surfaces and furniture, remain relatively cool. However, there are also many variables: The specific temperatures depend on which stove you are using, how long you have been cooking, how high you have set the temperature, and also on the cookware used. You should ensure that your pots and pans correspond as precisely as possible to the diameter of the respective cooking zone. And that you also place them in the middle of the cooking zone.
With an induction cooktop, the heat is generated exclusively in the base of the pot. If the pot or pan is removed, heat production is immediately paused. The cooktop underneath remains relatively cool. However, temperatures of up to 350°C can be reached under the pot, depending on the food and cooking process. In the event of improper
operation, such as an empty boiling (forgotten) pot, significantly higher temperatures of more than 500°C can be reached.
The residual heat indicator indicates hot cooking zones. This prevents burns on the one hand and helps save energy on the other, because the residual heat in radiant cooking zones can be used perfectly to continue cooking at low temperatures.
Provided you have suitable cookware, this cannot really happen. A temperature limiter automatically switches off the heating elements as soon as a certain temperature is exceeded. The final temperature setting, however, is performed by the manufacturer of the stove.
As the heat is generated directly and quickly in the base of the pot, food can also burn quickly. Only magnetizable pot bases (magnets remain attached to them) can be used. If the pot is removed from the cooking zone, the risk of burning is significantly reduced by the low temperature of the glass-ceramic, but nevertheless present. Heat production is immediately interrupted as soon as the cookware has been removed from the cooktop.
Cooking times are generally shorter for glass-ceramic cooktop panels than for conventional cooktops (mass cooktops) that are not made of glass-ceramic. And it depends heavily on the heating technology used. However, the boiling time is also determined by the nature of the cookware. Our recommendation: Trust
in steel enamel or stainless-steel pots with the right thickness. In the case of radiant heaters, special care must be taken to ensure that the base of the pot lies flat when hot.
The residual heat indicator integrated in most cooktops lights up until the cooking surface has cooled down to lukewarm. Please note: With gas stoves, the pot attachments/rests can become very hot depending on the cooking time.
We strongly advise against using such universal protective cloths, as covering the glass-ceramic also covers the temperature sensor and thus “insulates” it. The temperature sensor can then no longer determine the load temperatures correctly and there is a risk of the cooktop overheating.
