Stained glass firm founded in 1852 by Clement Heaton (1824-82), who was influenced by Pugin. Heaton's research into pigments resulted in an extended range of colours. Prior to establishing his own firm in London, he had previously worked for William Holland. James Butler (1830-1913) became a partner in 1855, and in 1862 Robert Turnill Bayne (1837-1915), who had worked with John Richard Clayton at Clayton & Bell, entered the partnership. The firm continued to be run by their sons and closed in 1953 following the death of Basil Richmond Bayne, by which time most of their work was for clients in North America.
