    摘要: A method and/or system is provided for detecting inclusions (e.g., nickel sulfide based inclusions/defects) in soda-lime-silica based glass, such as float glass. In certain example instances, during and/or after the glass-making process, following the stage in the float process where the glass sheet is formed and floated on a molten material (e.g., tin bath) and cooled or allowed to cool such as via an annealing lehr, visible light from an intense visible light source(s) is directed at the resulting glass and thermal imaging is used to detect inclusions based on a temperature difference between the inclusions and surrounding float glass. In another example embodiment, inclusion detection may be performed without exposure of the glass to light from a light source(s). Inclusions and surrounding glass may cool at different rates and be at different temperatures just prior to and/or after an annealing lehr, and a difference in residual temperature between inclusions and surrounding glass may be detected via thermal imaging and identified to identify inclusion(s).

    摘要: To provide granules for the production of silicate glass, said granules being less likely to adhere even if heated at a high temperature exceeding 800° C. A method for producing granules, which has a step of mixing a glass raw material composition composed essentially of an alkali metal source, an alkaline earth metal source and a powdery silicon source, with water, followed by compression molding, and which is characterized in that the glass raw material composition contains at least 50 mass % of the silicon source, and at least 10 mass % in total of the alkali metal source and the alkaline earth metal source, as calculated as oxides, based on 100 mass % of the silicate glass obtainable from the granules, the alkali metal source contains an alkali metal carbonate, and D90 representing the particle size at a cumulative volume of 90% in the particle size accumulation curve of the alkaline earth metal source is at most 100 μm.

    摘要: Certain example embodiments relate to an improved method of strengthening glass substrates (e.g., soda lime silica glass substrates). In certain examples, a glass substrate may be chemically strengthened by creating an electric field within the glass. In certain cases, the chemical tempering may be performed by surrounding the substrate by a plasma including certain ions, such as Li+, K+, Mg2+, and/or the like. In some cases, these ions may be forced into the glass substrate due to the half-cycles of the electric field generated by the electrodes that formed the plasma. This may advantageously chemically strengthen a glass substrate on a substantially reduced time scale. In other example embodiments, an electric field may be set in a float bath such that sodium ions are driven from the molten glass ribbon into the tin bath, which may advantageously result in a stronger glass substrate with reduced sodium content.

    摘要: A float glass system (10) includes a float bath (14) having a pool of molten metal (16). A chemical vapor deposition coater (32) is located in the float bath (14) above the pool of molten metal (16). The coater (32) includes at least one low-coherence interferometry probe (38) located in or on the coater (32) and connected to a low-coherence interferometry system (36). Another low-coherence interferometry probe 138 can be located outside an exit end of the float bath (14) and connected to the same or another low-coherence interferometry system (36).
