Methods, compositions, and articles provide for LAS-type glass-ceramics having specific thermo-mechanical, optical and coloration characteristics to yield generally brown-grey products. The glass-ceramic materials may include as colorants iron oxide, vanadium oxide, chromium oxide, cobalt oxide, nickel oxide and/or cerium oxide.

Non-opaque arsenic-free beta-spodumene glass ceramic exhibiting brown-grey coloration

The subject matter of the invention is a reinforced glass plate for an induction cooking device, the chemical composition of which comprises the following colorants, in a content which varies within the weight limits defined hereinafter: FeO(total iron): 0.8% to 1.8%, CoO: 0.02% to 0.06%, Se: 0 to 0.005%, CrO: 0 to 0.1%. The invention is also directed towards an induction cooking device comprising at least one inductor placed under such a glass plate.

Vitroceramic plate

A biocidal glass composition for use in roofing applications can include glass doped with at least one biocidal agent that includes about 0.01 wt. % to about 50 wt. % of a total weight % of the biocidal glass composition. The biocidal glass composition can be included in a coating on a base particle of a roofing granule. Further included is a process of forming the roofing granule.

Roofing granules

A domestic oven door includes an inner glass sheet intended to be the glass sheet closest to the compartment of the oven, and an outer glass sheet, the glass sheets being held rigidly connected and being separated by an air gap, the inner glass sheet possessing a chemical composition which includes the following constituents, in an amount by weight within the limits defined hereinafter:
