The glazing is welded by heating and later pressing. Triplex glasses exhibit the maximum impact resistance. This glazing system is distinguished for the optimal use of safety in use since, if it breaks, the glass pieces are held in place by means of the intermediate membranes, preventing serious injury.
Pilkington aggressively protected its patents and trade secrets through a network of licensing agreements with glass manufacturers around the world. The modern "float" technique (pouring the molten glass on a layer of very pure molten tin) became commercially widespread when Alastair Pilkington developed a practical version, patented in the late 1950s and early 1960s.
The float glass process is also known as the Pilkington process, named after the British glass manufacturer Pilkington, [4] which pioneered the technique in the 1950s at their production site in St Helens, Merseyside. [5] Modern windows are usually made from float glass, [6] though Corning Incorporated uses the overflow downdraw method. [7]
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.
1888: Machine-rolled glass introduced, allowing patterns. [5] 1898: Wired-cast glass first commercially produced by Pilkington [6] for use where safety or security was an issue. [7] 1959: Float glass launched in UK. Invented by Sir Alastair Pilkington. [8] [9]
By the end of 1952 Pilkington had assumed full financial control of Chance Brothers, but were not actively involved in its management until the mid- to late-1960s. When plastic disposable syringes displaced glass in the late 1960s, the range of its precision bore product was diversified. The production of flat glass ceased at Smethwick in 1976.
A study by University of Surrey and Pilkington Glass proposes that waste laminated glass be placed into a separating device such as a rolling mill where the glass is fragmented and the larger cullet is mechanically detached from the inner film. The application of heat then melts the laminating plastic, usually polyvinyl butyral (PVB), enabling ...
Sir Lionel Alexander Bethune Pilkington OBE FRS [1] (7 January 1920 – 5 May 1995), known as Sir Alastair Pilkington, was a British engineer and businessman who invented and perfected the float glass process for commercial manufacturing of plate glass.
