The Thames Plate Glass Company exhibit the largest plate of glass in the world; its dimensions are eighteen feet eight inches by ten feet. There is not a blemish on its brilliant surface, and it is as "true" as possible. It is placed in such a position that it reflects the whole length of the main avenue of the Crystal Palace, and the effect produced is superb.

R. W. Swinburne and Co. commenced business in 1845. The South Shields works occupied the quadrangular space now enclosed by Ferry Street, Station Road, Coronation Street, the Mill Dam and the Tyne river. The firm was successful in dividing with Messrs. Chance of Birmingham, the enormous order for the rolled plate-glass required in the erection of the Crystal Palace in 1850.
Early in 1858 a great combination of plate glass-makers, controlling practically the whole output of the works in England, was formed. Mr. R. W. Swinburne was appointed Managing Director of the Syndicate.
Swinburne returned briefly to the plate glass industry in January 1874 as a director of the Thames Plate Glass Company (1874) Limited which was formed to take over the dormant Thames Plate Glass Works at Blackwall, however this was wound up in August 1876.
Still looking for the reference to the part played by Thames Plate Glass Works (Not company) in Crystal Palace, this is a reasonably comprehensive 'looking' report http://www.british-history.ac.uk/report.aspx?compid=46545#s13
