Ceran

Ceran is a brand of lithium aluminosilicate glass-ceramic developed and manufactured by Schott AG. It is used as a material for cooktop surfaces in electric, induction, and gas stoves. Compared to traditional electric stoves with cast-iron plates, Ceran cooktops transfer heat directly to the cookware while the surrounding surface remains relatively cool. The material is highly resistant to thermal shock and can withstand temperature fluctuations of up to 700 °C. Introduced in 1971, Ceran initially became common in Germany, where the name is frequently used colloquially as a generic term for glass-ceramic cooktops, although this usage is technically inaccurate. The term "Ceran" has also received an entry in the Duden, the authoritative German language dictionary.
