Drawn glass process

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.
