The story of gunpowder production at Waltham Abbey
Waltham Abbey, Essex
Waltham Abbey is a market town of about 20,400 people in the south west of the county of Essex, in the East of England region. It is about 24 km north of London on the Greenwich Meridian and lies between the River Lea in the west and Epping Forest in the east. It takes its name from The Abbey...

, an engineered water course tapping the waters of the River Lea. Mills were adaptable and in the early 17th century it was converted to an 'Oyle Mill', i.e. for producing vegetable oils. In the Second Dutch War gunpowder supply shortages were encountered and the oil mill was converted to gunpowder production, possibly in response to this. In 1665 it was acquired by Ralph Hudson using saltpetre
Potassium nitrate
Potassium nitrate is a chemical compound with the formula KNO3. It is an ionic salt of potassium ions K+ and nitrate ions NO3−.It occurs as a mineral niter and is a natural solid source of nitrogen.

The Hudson family sold out to William Walton at the end of the 17th century, starting a family connection lasting almost a hundred years. The enterprise was successful under the Walton's tenure and the Mills expanded up the Millhead Stream

 as additional production facilities were added; the material progressing from one building to another as it passed through the various processes. The Waltham Abbey Mills were one of the first examples in the 18th century of an industrialised factory system, not often recognised. In 1735 they were described by Thomas Fuller, a local historian, as 'the largest and compleatest works in Great Britain.'

Purchase of the site by the Crown

In the 1780s there was fresh concern over security, quality and economy of supply. The then Deputy Comptroller of the Royal Laboratory at Woolwich
Royal Arsenal

, Major, later Lt. General, Sir William Congreve advocated that the Waltham Abbey Mills should be purchased by the Crown to ensure secure supplies and to establish what would now be called a centre of excellence for development of manufacturing processes and to establish quality and cost standards by which private contractors could be judged. In October 1787 the Crown purchased the Mills from John Walton for £10,000, starting a 204 year ownership. Congreve was a man of immense drive and vision, a pioneer of careful management, quality control and the application of the scientific method. Under his regime manufacture moved from what had been a black art to, in the context of its day, an advanced technology.

 for use in guns, or as a military explosive for demolition, etc., improvements effected there were a strong influence on private industry producing for civil activity - construction, mining, quarrying, tunneling, railway building etc. which created a massive demand for gunpowder in the 19th century.

Research into other explosives

Under the leadership of Sir Frederick Abel, first, Guncotton was developed at Waltham Abbey, patent

, patented in 1889.

Again there was a close link with production for civil use, with chemical engineering improvements at Waltham Abbey being disseminated to private industry. All this meant that Waltham Abbey had become a leading centre of Victorian and later science and technology, but for reasons of security largely unknown to the outside world.

World War I

World War I
World War I
World War I , which was predominantly called the World War or the Great War from its occurrence until 1939, and the First World War or World War I thereafter, was a major war centred in Europe that began on 28 July 1914 and lasted until 11 November 1918...

 1914 - 1918 brought a huge upsurge in demand. The Mills increased staff numbers by around 3000 to a total of 6230. The 3000 additional workers were largely female, recruited from the surrounding area and this was a significant social phenomenon.
After WWI there was again a period of quiet before anxieties about the future again surfaced. It was decided that production at Waltham Abbey would be gradually transferred to the west of the country, safer from air attack from Europe. However in the meantime production continued and crucial development work was carried out on TNT production and on the new explosive RDX
RDX

The Royal Gunpowder Mills finally closed on 28 July 1945.

After various reorganisations of Governmental research, the research centre finally closed in 1991, bringing to an end 300 years of explosives production and research.
