The invention relates to a method and to a device for ceramizing green glass in a continuous furnace, with the ceramization being carried out directly on rollers.

Glass ceramic article and method and device for ceramizing glass

The method produces a glass-ceramic article substantially in the form of a plate with improved high temperature difference resistance or strength. The glass-ceramic article contains keatite mixed crystals (KMK) or high quartz mixed crystals (HQMK) as well as the keatite mixed crystals (KMK). The method includes heating a glass-ceramic in a high quartz mixed crystal state to form the keatite mixed crystals with a heating rate of 20 K/min to 150 K/min, preferably more than 15 K/min, especially preferably more than 20 K/min. These high heating rates increase the temperature difference resistance.

Method of making a glass-ceramic article

There is disclosed a stove, with a smooth-top cooktop, for cooking food, the stove comprising: a stove body; a smooth-top cooktop to cook food thereon; and at least one heat source disposed adjacent to a cooking surface of said cooktop. The cooktop comprises glass ceramic with an upper layer and an inner layer, with the upper layer comprising a different glass ceramic material than the inner layer. The upper layer is configured to minimize surface defects such as fissures, cracks, pits, and pores. The inner layer is configured to provide resistance to impact to the upper layer from cooking utensils being dropped onto the upper layer of the smooth-top cooktop, and at least the inner layer of the glass ceramic being configured to obscure visibility of the at least one heat source, through the upper layer of the glass ceramic.

COOKING STOVE HAVING A SMOOTH-TOP GLASS CERAMIC COOKTOP, AND A SMOOTH-TOP GLASS CERAMIC COOKTOP WITH A GLASS CERAMIC COOKTOP COOKING SURFACE, METHOD FOR PRODUCTION OF STOVES WITH SMOOTH-TOP GLASS CERAMIC COOKTOPS AND SMOOTH-TOP GLASS CERAMIC COOKTOPS
