Scratch-resistant cooking surfaces: Bosch relies on SCHOTT CERAN Miradur®

Monday, October 26, 2020, Mainz, Germany

  • The new Series 8 premium cooktops from Robert Bosch Hausgeräte GmbH are particularly well prepared for everyday use in the kitchen: This is because the glass ceramic cooktops impress with a special coating that is almost as hard as a diamond.
  • The feature that Bosch calls "GlassProtect" is a patented development from SCHOTT, the inventors of black glass-ceramic for cooking: CERAN®. A special coating technology makes the cooking surface harder, significantly reduces scratches and thus ensures a long-lasting shine.

Quality is the main focus of the new Bosch Series 8 premium cooktops. Modern cooking features such as the flexible interconnection of induction cooking zones ("FlexInduction") or the "PerfectFry" frying sensor, which prevents burning, make cooking more flexible and easier. What remains are the demands placed on the glass-ceramic cooktop: it has to cope with a lot in kitchens, because plates, pans, cleaning agents and even food leave their marks in everyday use.

Above all, dirt, dust or tiny grains of sand that get onto the hob from shopping bags have a tough time: due to their angular structures, they quickly cause deep scratches that damage the beauty of the glass-ceramic surface. The same applies to abrasive kitchen sponges. Especially under high pressure, the hard scrubbing fleece on the underside quickly produces visually noticeable, fine scratches. With "GlassProtect", however, stress does not mean wear and tear. The coating makes the cooking surface 95% more scratch-resistant to sand and 70% more scratch-resistant to abrasive sponges.

The beauty and strength of CERAN Miradur®

"GlassProtect" has it all: Robert Bosch Hausgeräte GmbH, for example, relies on the many years of research and expertise of SCHOTT and its coated glass-ceramic CERAN Miradur®. Miradur® belongs to the family of the original, CERAN®, and is the only coated glass-ceramic in the specialty glass expert's portfolio that is almost as hard as a diamond – and more than twice as scratch-resistant as conventional glass-ceramic cooktop panels. This makes it extremely resistant and can withstand scratches and intensive use for years without losing its beauty.

The 0,8 meters wide induction cooktops of the 8 series, PXV820DV5E and PXV890DV5E, come with "GlassProtect" / CERAN Miradur® as standard. Thanks to their elegant design, they fit into modern kitchen concepts and, thanks to their special coating, maintain the smooth and shiny surface of the glass ceramic for a long time. The models will be available in Germany, Austria and the Netherlands from December.

Exceptionally strong

SCHOTT CERAN Miradur® is certified by TÜV Rheinland for scratch resistance and quality as well as controlled manufacturing. Miradur® is also patented by SCHOTT as a scratch-resistant glass-ceramic for glass-ceramic cooktops.
