Scope and Content Glue & Gelatine Manufacturer, J & G Cox Ltd, Gorgie Mills (Gorgie Glue Works), Gorgie Road, Edinburgh This works was probably founded in about 1900 by J & G Cox Ltd, and made crystal gelatine and animal glue from hides. These were treated with lime and then with hydrochloric acid, then boiled to extract soluble proteins. The protein solution was concentrated in a vacuum in an evaporator. This shows the steam-driven vacuum pump of one of the three evaporators in the works. This one is a double-effet one of the Yaryan type made in 1903 by Mirrlees Watson. The evaporator chambers, called 'effets', are above and to the left, and concentrate the solution in two stages. The works was also known as Gorgie Mills. Latterly it was owned by Bryant & May, match manufacturers, who used the glue as a component of their match heads. Owing to declining demand for matches, the company pulled out of Scotland in 1969. This factory was demolished soon afterwards. Source: RCAHMS contribution to SCRAN.
