    en.wikipedia.org/wiki/Glass_production

    Float glass is a sheet of glass made by floating molten glass on a bed of molten metal, typically tin, although lead and various low melting point alloys were used in the past. This method gives the sheet uniform thickness and very flat surfaces.

  3. Glass melting furnace - Wikipedia

    en.wikipedia.org/wiki/Glass_melting_furnace

    Glass Furnace by Siemens hist. 1878 Siemens Regenerator Furnace hist. 1885 in 4 Views. A glass melting furnace is designed to melt raw materials into glass. [1] Depending on the intended use, there are various designs of glass melting furnaces available. [2] [3] [4] They use different power sources. These sources are mainly fossil fueled or by ...

  4. Refining (glass) - Wikipedia

    en.wikipedia.org/wiki/Refining_(glass)

    Glass types that melt at comparatively high temperature, such as borosilicate glasses, use chlorides, such as NaCl, having a sufficiently high vapour pressure at refining temperatures. Alkali-free glasses with high melting temperature, such as LC display glasses, use tin oxide, SnO 2. In the following cooling process gases from bubbles are ...

  5. Glass - Wikipedia

    en.wikipedia.org/wiki/Glass

    Fibreglass (also called glass fibre reinforced plastic, GRP) is a composite material made by reinforcing a plastic resin with glass fibres. It is made by melting glass and stretching the glass into fibres. These fibres are woven together into a cloth and left to set in a plastic resin.

  6. Soda–lime glass - Wikipedia

    en.wikipedia.org/wiki/Soda–lime_glass

    The manufacturing process for soda–lime glass consists in melting the raw materials, which are the silica, soda (Na 2 O), hydrated lime (Ca(OH) 2), dolomite (CaMg(CO 3) 2, which provides the magnesium oxide), and aluminium oxide; along with small quantities of fining agents (e.g., sodium sulfate (Na 2 SO 4), sodium chloride (NaCl), etc.) in a glass furnace at temperatures locally up to 1675 ...

  7. Borosilicate glass - Wikipedia

    en.wikipedia.org/wiki/Borosilicate_glass

    Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.

    After these men purchased a rotary pressing machine and a continuous tank to melt glass, “…Hocking’s sales increased from $20,000 during the factory’s first year to $900,000 (more than $12 ...

  9. Glass batch calculation - Wikipedia

    en.wikipedia.org/wiki/Glass_batch_calculation

    The batching matrix B indicates the relation of the molarity in the batch (columns) and in the glass (rows). For example, the batch component SiO 2 adds 1 mol SiO 2 to the glass, therefore, the intersection of the first column and row shows "1". Trona adds 1.5 mol Na 2 O to the glass; albite adds 6 mol SiO 2, 1 mol Na 2 O, and 1 mol Al 2 O 3 ...
