LIGHT-SCATTERING GLASS ARTICLES AND METHODS FOR THE PRODUCTION THEREOF

According to embodiments disclosed herein, light-scattering laminated glass articles may include a first glass layer, a second glass layer, and a light-scattering component. The first glass layer may be formed from a first glass composition. The second glass layer may be formed from a second glass composition and fused to the first glass layer. The light-scattering component may be disposed at an interface of the first glass layer and the second glass layer. The light-scattering component may include a different composition or material phase than the first glass layer and the second glass layer. Also disclosed herein are methods for producing light-scattering laminated glass articles.

INCLUDING SMALL AESTHETIC BUBBLES IN GLASS ARTICLES

A method of forming glass articles involves introducing a particulate mixture (20) of SiC particles and carrier particles into molten glass (44, 22) contained within at least one of a forehearth (12) or a fining chamber (28) of a glass-making furnace (10). The particulate mixture (20) creates seeds (S) within the molten glass such that an outflow of conditioned molten glass (18) discharged from the forehearth (12) and the glass articles produced therefrom contain a greater concentration of seeds (S) than if the particulate mixture (20) is not added. The concentration of seeds (S) in the glass articles can be controlled by commencing or withholding the addition of the particulate mixture (20).

Provided is a glass production method with which oxidation can be suppressed and productivity can be increased. A glass production method according to the present invention includes the steps of: turning a raw material 6 placed in a container 1 into a melt 11; homogenizing the melt 11; removing a gas from the melt 11, wherein at least one of the step of turning the raw material 6 into the melt 11 and the step of homogenizing the melt 11 is performed in an atmosphere of an inert gas or a reducing gas, and in the step of the removing the gas from the melt 11, the inert gas or the reducing gas is removed by setting the temperature of the melt 11 to be lower than the temperature in the step of homogenizing the melt 11.

Glass manufacturing apparatus and methods

Low-carbon monolithic refractories are provided. Methods of manufacturing glass employing low-carbon monolithic refractories are also provided. Methods and apparatuses for glass manufacture for reducing the formation of carbon dioxide blisters during glass manufacture are also provided.

Glass ceramics having low rhodium levels

A glass ceramic precursor glass and a glass ceramic having low levels of rhodium and a method of controlling the amount of rhodium in such glasses and glass ceramics. The precursor glass and glass ceramic contain from about 1 ppm to about 10 ppm and, in certain embodiments, from about 1 ppm to about 6 ppm rhodium. The method of controlling of reducing rhodium dissolution from a rhodium-containing material such as, for example, an alloy into a glass melt comprises controlling and/or lowering the partial pressure of oxygen at the rhodium-containing vessel/glass interface by imposing a high humidity condition around the external (non-glass-contact) surface of the rhodium-containing material. The lower concentration of rhodium minimizes its coloring effect on the white color of the glass ceramic.
