Know-how, what, and where. All the answers to your questionsIt is important to us that SCHOTT CERAN® gives you the best quality and a special cooking experience, as well as comprehensive service. This includes useful tips and answers to all the questions you might have: about the product and its properties, operating instructions or manuals and possible error messages, as well as many other topics related to glass-ceramic cooktops and surfaces.
In these rare cases.
Although unlikely, your CERAN® glass-ceramic cooktop may not function as intended. Your first point of contact, in this case, should be the manufacturer of your stove or cooking appliance, because they are the ones who installed this vital component in the appliance. You can also obtain practical information on your cooktop from the manufacturer, such as the operating instructions/manual, and receive competent support in the event of device-related error messages. If you have any questions about our products or suggestions of a general nature, we are, of course, always happy to assist you with advice, action, or information.
About CERAN® and glass-ceramic.
A cooktop powered by radiant heat, gas, or induction with a glass-ceramic surface. Our CERAN® brand name has becomeestablished in all languages for glass-ceramic cooktops. CERAN® stands for the trademark established and protected by SCHOTT.
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.
The function depends on the selected heating system:
- Radiant heating: The glass-ceramic surface developed by SCHOTT transfers the heat generated by the radiator beneath the cooking surface to the bottom of the cookware. As the material isonly a few millimeters thick, the heat transfer is particularly efficient.
- Induction: A coil with current flowing under the cooking surface generates an electromagnetic field. This causes eddy currents to flow through the glass-ceramic and onto special cookware made of ferromagnetic material, which heat the metal of the pot. The pot transfers then the heat up to the food.
- Gas: A burner above the glass-ceramic panel heats the pot sitting on the pot rests.
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.
Types of heating (electric, gas, or induction).
Cooking with CERAN®.
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.
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.

Cleaning and care.
A SCHOTT CERAN® glass-ceramic cooktop panel should ideally be cleaned quickly after every cooking process. The following procedure is recommended:
First, remove heavy soiling with a suited metal scraper.
Then use a clean cloth to rub a few drops of a suitable cleaning agent onto the cold cooking surface.
Finally, wipe down the SCHOTT CERAN® glass-ceramic cooking surface using a wet cloth and rub dry.
SCHOTT CERAN Miradur®.
At the end of the day, a cooking surface is always there to be used – but signs of use do not have to be inevitable. That’s why we developed SCHOTT CERAN Miradur®, a glass-ceramic with significantly lower scratch sensitivity. This way you can concentrate on the cooking experience – and enjoy a cooking surface for many years that looks the same as it did on the first day.y a cooking surface for many years that looks the same as it did on the first day.
Damage and warranty.
Scratches, marks, and maintenance.
Scratches are never nice. But unfortunately, they occur sometimes. It is important that they do not affect the stability of the glass-ceramic cooktop panel. Instead of being annoyed afterwards, it is better to do everything beforehand to avoid scratches:
- Only use care products and utensils that bear the SCHOTT seal of approval.
- Always make sure that the blade is intact when using the scraper.
Important: Mineral particles such as sand should not come into contact with the glass-ceramic cooking surface – e.g. due to dirty vegetables or bags placed on the cooktop.
“Marks” are often signs of wear caused by unsuitable, aggressive cleaning agents. These include scouring cream, oven spray, or hard sponges. Therefore, pay attention to suitable care and cleaning utensils, as these “stains” cannot be removed.
Especially aluminum or copper pot bases can leave shimmering metallic stains. These should be removed immediately using suitable care products. Once they burn on, they can rarely be removed.
For optimal cooking results, use stainless-steel cookware with a sandwich base of 4–6 mm thickness or crockery made of steel enamel with a 2–3 mm base thickness. Cookware with a smooth base is also important.
The base of the cookware should be clean, dry, and free of rough edges. It is also advisable not to move pots over the cooking surface, but to lift them.
A special case: Induction cooking only works with magnetizable cookware. Whether the cookware is suitable can be quickly tested: Simply hold a magnet to the bottom and see if it sticks.
We particularly advise against pots with a copper or aluminum base. These can leave marks that are difficult to remove. Glass-ceramic cookware is also not recommended. It conducts the heat too poorly.
