A method for producing a glass article having high hydrolytic resistance is provided. A glass tube consisting of borosilicate glass and having an AlOcontent of less than 1 weight-%, a ZrOcontent of 2-12 weight-%, and a glass transition temperature Tis reshaped into a glass article and is subsequently subjected to a thermal post-treatment. To reduce the alkali release of the glass article, the glass article is subjected to a treatment temperature of T&#x2265;T+5&#xb0; K over a treatment time of t&#x2265;5 min and is subsequently cooled during the thermal post-treatment.

An optical converter for producing colored or white light from blue excitation light is provided. The converter has good scattering properties to be able to produce nearly white light from the scattered blue light components and the scattered, converted yellow light components. The optical converter includes material including one or more of a YAG ceramic, a LuAG ceramic, and a magnesium-aluminum ceramic exhibiting strong scattering.

Borosilicate glasses, preferably for use in the pharmaceutical sector, are provided. The borosilicate glasses are outstandingly suitable for the use as pharmaceutical primary packaging, such as phials or ampoules, since the aqueous or water-containing medicaments kept in the containers do not attack the glass significantly, and so the glass releases no, or only few, ions. The borosilicate glasses have the following composition in % by weight or consist thereof:

This invention relates to a flat float glass that can be prestressed or transformed into a glass ceramic with high quartz mixed crystals or keatite mixed crystals. To eliminate undesirable surface defects during floating and to achieve superior characteristics of the glass or of the glass ceramic, in particular with regard to a low coefficient of thermal expansion and high light transmittance, the glass has a concentration of less than 300 ppb Pt, less than 30 ppb Rh, less than 1.5 wt. % ZnO and less than 1 wt. % SnO, and is refined during melting without the use of the conventional fining agents arsenic oxide and/or antimony oxide.

The cooking unit has a glass-ceramic panel () providing a cooking surface, which is made of transparent colorless glass-ceramic bulk material or a glass panel made of pre-stressed transparent colorless glass material. Radiant heating elements () are provided under the glass or glass-ceramic panel, which heat respective cooking zones. The glass or glass-ceramic panel has a full surface decorative coating () on its upper side, which makes dirt and usage marks less conspicuous, and an IR permeable coating () having a solid or plain color, preferably bisque-like, on its underside. The IR permeable coating having the solid or plain color prevents an observer from viewing the internal components of the cooking unit that are under the cooking panel from above it.

A cooking stove having a cook top, or hob, for cooking food, components thereof, and method of production. The stove has a stove body, a smooth-top cook top with a cooking surface to cook food thereon, and a heat source disposed adjacent to the cooking surface. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. &#xa7;1.72(b). As stated in 37 C.F.R. &#xa7;1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading 'Abstract of the Disclosure.' The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, the abstract is not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.

The cover comprises an inner surface facing the interior of the lamp and an outer surface facing away from the lamp. At least the outer surface facing away from the lamp comprises unpolished glass configured to provide the unpolished surface. The unpolished glass of the outer surface comprises a surface having a roughness which is minimized.

There is now provided a kitchen stove for preparing food, and an oven for preparing food. The stove or oven has a heating arrangement to make the cleaning of the stove or oven easier for a user particularly at the viewing window of the oven.

Kitchen stove for preparing food, and an oven for preparing food

A cooking surface for a cooktop. Encrusted, spilled, or overflowing food is deposited on the cooking surfaces of cooktops during cooking and the removal of such residue is difficult because the surface of a cooktop is typically rough and uneven. The invention teaches the manufacture of an easy-to-clean glass ceramic cooktop from a floated glass ceramic. As a result of the increased use of controls in cooking devices, an increased number of displays are also being used under the surface of the cooktops. The invention provides a cooktop with a smooth, distortion-free surface that is easy to clean. The invention also relates to window panes for enclosed hot areas with high temperatures, which are typically made of transparent glass ceramic. When used as windows in warming stoves or in self-cleaning ovens, combustion residues are thereby deposited on the windows, which residues must then be removed. It is difficult to clean a window of this type, because the surface of the transparent glass ceramic that is manufactured using conventional methods is typically structured and uneven. The invention teaches the manufacture of an easy-to-clean class ceramic window body from a floated glass ceramic that has a specified surface quality that is comparable to that of a floated soda lime glass pane. The invention also relates to a stove for cooking food with an easy-to-clean oven window and an easy-to-clean cooktop.
