Kynoch was established in Witton in Birmingham in 1862 by Scottish entrepreneur George Kynoch when he opened a percussion cap factory in Witton.[1] In 1895 he built an explosives factory east of Shell Haven Creek, Essex (now known as Coryton). This opened in 1897, with an estate for employees called Kynochtown. Products included cordite, guncotton, gunpowder, and cartridges.[2] After World War I many of the UK ammunition and explosives manufacturers were brought together under Nobel Explosives to become Nobel Industries, which was a founding element of Imperial Chemical Industries Ltd (ICI) in 1926. Once Nobel Industries, including Kynoch Ltd, had merged to form ICI, the original Kynoch factory in Witton became the head office and principal manufacturing base of the "ICI Metals Division". Kynoch, along with names such as Eley, became brands of subsidiaries
