 From September 1836 to the end of 1837 the Eglinton Estate purchased between 5,000 and 10,000 tiles per month for use on its farms.The fate of the tileworks is revealed in the memoranda from George Johnston, the Earl of Eglinton’s factor, to the Earl’s Commissioner, Mr Gairdner.By the end of 1852 demand for tiles had fallen considerably, production however was not reduced.
