  2. Glass production - Wikipedia

    en.wikipedia.org/wiki/Glass_production

    Broadly, modern glass container factories are three-part operations: the "batch house", the "hot end", and the "cold end". The batch house handles the raw materials; the hot end handles the manufacture proper—the forehearth, forming machines, and annealing ovens; and the cold end handles the product-inspection and packaging equipment.

  3. Lehr (glassmaking) - Wikipedia

    en.wikipedia.org/wiki/Lehr_(glassmaking)

    Inspector at the cool end of a lehr. In the manufacture of float glass, a lehr oven is a long kiln with an end-to-end temperature gradient, which is used for annealing newly made glass objects that are transported through the temperature gradient either on rollers or on a conveyor belt.

  4. Fourcault process - Wikipedia

    en.wikipedia.org/wiki/Fourcault_process

    The Fourcault process is a method of manufacturing plate glass. First developed in Belgium by Émile Fourcault (1862–1919) during the early 1900s, the process was used globally. Fourcault is an example of a "vertical draw" process, in that the glass is drawn against gravity in an upward direction. [1] Gravity forces influence parts of the ...

    The machine withdrew the molten glass and blew a cylinder as the first step in Cylinder method for making window glass—replacing the task of highly skilled and highly-paid glassblowers. [60] An application for a patent on the Lubbers machine was filed during 1900, and a patent for "Apparatus for Drawing Glass" was issued in 1902. [ 61 ]

  6. Precision glass moulding - Wikipedia

    en.wikipedia.org/wiki/Precision_glass_moulding

    Precision glass moulding is a replicative process that allows the production of high precision optical components from glass without grinding and polishing. The process is also known as ultra-precision glass pressing. It is used to manufacture precision glass lenses for consumer products such as digital cameras, and high-end products like ...

    en.wikipedia.org/wiki/History_of_glass

    Oldest archaeology excavations of glass-making sites date to around 1250 and are located in the Lusatian Mountains of Northern Bohemia. Most notable sites of glass-making throughout the ages are Skalice (German: Langenau), Kamenický Šenov (German: Steinschönau) and Nový Bor (German: Haida). Both Nový Bor and Kamenický Šenov have their ...

    Owens was also involved with improving a process that used a machine for making window glass, which changed the way window glass was produced. [100] To accomplish the change in window glassmaking, Owens hired Irving Wightman Colburn after purchasing his patents involved with the new process.

  9. Glass melting furnace - Wikipedia

    en.wikipedia.org/wiki/Glass_melting_furnace

    However, oxygen-fired glass furnaces are usually not viable for the production of bulk glass, such as hollow and flat glass, due to the high cost of oxygen production. There are many different types of glass melting furnaces. The types of furnaces used in glass manufacturing include the so-called "end-fired", "side-fired" and "oxy-fuel" furnaces.
