The Fourcault process is a method of manufacturing plate glass. First developed in Belgium by Émile Fourcault [fr] (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. Gravity forces … See more The Fourcault process requires a "pit" or drawing area and an assembly of machines to draw up the ribbon of glass while performing actions upon it that ensure desired quality and process yields. Today most glass … See more Time, speed and spacing of the various phases of the process are critical factors in the Fourcault process. Fourcault process machine operators … See more The Fourcault process uses a ceramic die to shape fused (or molten) glass into a ribbon of rectangular cross section. The die, known as a debiteuse, floats in the molten glass inside … See more Some manufacturers also will apply sulfur dioxide gas during the draw in order to change the chemistry of the glass on the surface. By changing the chemistry it is possible to affect the surface characteristics of the glass, improving its quality and durability. See more WebFusion-drawn glass is particularly well-suited to the ion-exchange chemical strengthening process that has made Gorilla Glass the standard in tough electronic device covers.

WebWith Corning’s proprietary fusion process, the glass is formed in air and drawn down to form an incredibly flat piece of glass with very precise thickness controls. Substrate flatness is particularly critical in the production of panels for liquid crystal display (LCD) TVs. Any deviations from flatness can result in distortions. WebEvidence of large-scale drawn-glass bead making has been found by archeologists in India, at sites like Arekamedu dating to the 2nd century CE. ... The pulling was a skilled process, and canes were reportedly drawn to lengths up to 200 feet (61 m) long. The drawn tube was then chopped, producing individual drawn beads from its slices. The ... WebFeb 20, 2024 · The drawn glass process is also used to produce flashed glass, which consists of a clear basic glass overlaid with a thin layer of coloured or milky glass (white fl ashed opal glass, e.g. Opalika).
