Silica-titania glasses with small temperature variations in coefficient of thermal expansion over a wide range of zero-crossover temperatures and methods for making the glasses. The method includes a cooling protocol with controlled anneals over two different temperature regimes. A higher temperature controlled anneal may occur over a temperature interval from 750 C.-950 C. or a sub-interval thereof. A lower temperature controlled anneal may occur over a temperature interval from 650C.-875 C. or a sub-interval thereof. The controlled anneals permit independent control over CTE slope and Tzc of silica-titania glasses. The independent control provides CTE slope and Tzc values for silica-titania glasses of fixed composition over ranges heretofore possible only through variations in composition.

A glass food and beverage container constructed of 100 wt. % recycled glass-forming materials selected from the group consisting of post-industrial cullet, post-consumer cullet, and a combination thereof.

A glass laminate for an architectural element has a glass substrate coupled to the architectural element and defines a primary surface facing away from the architectural element. A phase-separable glass cladding is coupled to the primary surface. The cladding has an interconnected matrix with a first phase composition and a second phase that has a second phase composition different than the first phase composition. The second phase is distributed throughout the interconnected matrix. A copper phase is distributed within the interconnected matrix. The glass cladding has an antimicrobial log kill rate greater than about 4 as measured by an EPA Copper Test Protocol.

A method of bleaching a glass-ceramic article is disclosed. The method includes irradiating a first portion of a bulk of the glass-ceramic article by directing a beam from a laser into a thickness of the bulk to heat the first portion and form a first aperture therein. The bulk is configured to have an amorphous silicate glass phase. a crystalline phase. and a bulk transmittance. The first aperture is configured to have a first transmittance that is greater than the bulk transmittance at first wavelengths from about 350 nm to about 2500 nm. The beam from the laser is configured to include a bleaching wavelength selected from a laser wavelength band within which residual absorption persists in the aperture after the irradiating at the bleaching wavelength.

Disclosed is a low-expansion borosilicate transparent glaze, a preparation method thereof, and use thereof in preparation of a glaze product by secondary fusion-cast molding. The low-expansion borosilicate transparent glaze has raw material composition by mass percentage including: 72%-80% of SiO.sub.2, 4%-12% of B.sub.2O.sub.3, 4%-12% of Na.sub.2O, 0.1%-4% of CaO, 0.1%-6% of Al.sub.2O.sub.3, 0-0.05% of Fe.sub.2O.sub.3, 0-2% of MgO, 0-2% of K.sub.2O, 0-2% of ZnO, 0-2% of BaO, 0-2% of ZrO.sub.2, 0-0.5% of Li.sub.2O, and 0-0.5% of TiO.sub.2, wherein a sum of mass percentages of SiO.sub.2, B.sub.2O.sub.3 and Al.sub.2O.sub.3 is 85%-95%. The preparation method includes steps of: (1) after mixing dried raw materials, melting at 1400-1540 C. to obtain a high-temperature glass melt; (2) cooling the high-temperature glass melt to 1150-1230 C. to mold; and (3) annealing a molded glass at 530-600 C. to obtain the low-expansion borosilicate transparent glaze.

A curved glass and a preparation method is provided. The preparation method for curved glass includes: melting a glass batch into a glass liquid, and clearing the glass liquid; introducing the cleared glass liquid into a mold cavity with a preset shape, and forming, by using a compression molding process, a glass product with a shape corresponding to that of the curved glass, where a size of the glass product is greater than a size of the curved glass; annealing the molded glass product; and processing the annealed glass product into the curved glass based on the shape and the size of the curved glass.
