In the consumer market, glass-ceramics from Schott are used in cooktops for electric, gas, and induction cooking under the brand name CERAN. [32] In industry, its glass-ceramic Zerodur is used in microlithography and as mirror substrates for large optical telescopes [33] such as:
Today, there are two major types of electrical stoves with cooktops made of glass-ceramic: A radiant heating stove uses coils or infrared halogen lamps as the heating elements. The surface of the glass-ceramic cooktop above the burner heats up, but the adjacent surface remains cool because of the low heat conduction coefficient of the material.
The DOE test cycle starts with both the block and the cooktop at 77 °F ± 9 °F (25 °C ± 5 °C). The cooktop is then switched to maximum heating power. When the test block temperature reaches 144 °F (80 °C) above the initial room temperature, the cooktop power is immediately reduced to 25% ± 5% of its maximum power.
From 1911, Schott manufactured borosilicate glass tubing for the production of pharmaceutical ampoules and vials. [8] Schott Pharma was established as a standalone company in 2022 under the name Schott Pharma AG & Co. KGaA [9] [6] through an equity carve-out (or spin-off) from Schott AG, a manufacturer of specialty glass and glass-ceramics.
William C. Schott was a philanthropist providing funds for a local hospital wing and murals for Western Hills High School, besides donating land for Schott Fields. Lucia Schott predeceased her husband by nearly a decade, but Will lived at Pine Meer for over fifty-five years, passing away at his home in 1981 at the age of 97.
