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.

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 ...
In 1952 Pilkington invented the float glass process, in which molten glass was "floated" over a bath of molten tin and manipulated to achieve the required product thickness, [5] and with his associate Kenneth Bickerstaff, [6] spent seven years perfecting and patenting its commercially successful manufacture. American inventors had tried several ...
A popcorn ceiling, also known as a stipple ceiling or acoustic ceiling, is a ceiling with one of a variety of spray-on or paint-on treatments. [1] The bumpy surface is created by tiny particles of vermiculite or polystyrene, which gives the ceiling sound-deadening properties. Mixtures are available in fine, medium, and coarse grades. [2]
