Early 1850s, H. P. Bun (H. P. Burt?) opened a tar distillery at Millwall, London.
In 1876 H. P. Burt bought the dyestuffs works at Greenford Green (where alizarin manufacture had originally been developed by W. H. Perkin) from Brooke, Simpson and Spiller. With it they acquired the rights to work the alizarin patents. They transferred the manufacture to Silvertown the following year.
1881 The Alizarin Convention, a cartel designed to regulate the price of alizarin dyes and allocate sales quotas, was founded by nine German manufacturers and one English firm, Burt, Boulton and Haywood (who had a quota of slightly under 10% of the total).
When the formation of the Alizarin Convention brought a threat of increased prices, the main consumers in Britain - Turkey-red dyers, especially in Scotland, and calico-printers - raised funds to buy a controlling interest in the Silvertown works, as the British Alizarine Co. Ltd.
1882 The company was registered on 14 December, to manufacture from coal-tar products a colouring matter know as alizarine.
