Northwich is a market and port town and civil parish in the unitary authority of Cheshire West and Chester in the ceremonial county of Cheshire, England. It lies in the heart of the Cheshire Plain, at the confluence of the rivers Weaver and Dane. The town is about 18 miles (29 km) east of Chester, 15 miles (24 km) south of Warrington, and 19 miles (31 km) south of Manchester.
The Leblanc process was an early industrial process for making soda ash used throughout the 19th century, named after its inventor, Nicolas Leblanc. It involved two stages: making sodium sulfate from sodium chloride, followed by reacting the sodium sulfate with coal and calcium carbonate to make sodium carbonate. The process gradually became obsolete after the development of the Solvay process.
The Solvay process or ammonia–soda process is the major industrial process for the production of sodium carbonate (soda ash, Na2CO3). The ammonia–soda process was developed into its modern form by the Belgian chemist Ernest Solvay during the 1860s. The ingredients for this are readily available and inexpensive: salt brine (from inland sources or from the sea) and limestone (from quarries). The worldwide production of soda ash in 2005 was estimated at 42 million tonnes, which is more than six kilograms (13 lb) per year for each person on Earth. Solvay-based chemical plants now produce roughly three-quarters of this supply, with the remaining being mined from natural deposits. This method superseded the Leblanc process.
Ludwig Mond FRS was a German-born British chemist and industrialist. He discovered an important, previously unknown, class of compounds called metal carbonyls.
Sir John Tomlinson Brunner, 1st Baronet, was a British chemical industrialist and Liberal Party politician. At Hutchinson's alkali works in Widnes he rose to the position of general manager. There he met Ludwig Mond, with whom he later formed a partnership to create the chemical company Brunner Mond & Co., initially making alkali by the Solvay process. As a Member of Parliament he represented Northwich, Cheshire, in 1885–1886 and then from 1887 to 1910. He was a paternalistic employer and as a politician supported Irish Home Rule, trade unions, free trade, welfare reforms and, leading up to the First World War, a more sympathetic stance towards Germany. Brunner was a prominent Freemason, and a generous benefactor to the towns in his constituency and to the University of Liverpool. He is the great grandfather of the Duchess of Kent.
Winnington is a small, mainly residential area of the town of Northwich, in the Cheshire West and Chester district, in the ceremonial county of Cheshire, England.
William Gossage was a chemical manufacturer who established a soap making business in Widnes, Lancashire, England.
Tata Chemicals Europe is a UK-based chemicals company that is a subsidiary of Tata Chemicals Limited, itself a part of the India-based Tata Group. Its principal products are soda ash, sodium bicarbonate, calcium chloride and associated alkaline chemicals.
John Hutchinson was a chemist and industrialist who established the first chemical factory in Widnes, then Lancashire now Cheshire, England. He moved from working in a chemical factory in St Helens and built his own chemical factory in 1847 in the Woodend area of Widnes near to Widnes Dock by the junction of the Sankey Canal and the River Mersey. In this factory he manufactured alkali by the Leblanc process.
Henry Deacon was a chemist and industrialist who established a chemical factory in Widnes, Lancashire, England.
Edmund Knowles Muspratt was an English chemical industrialist.
Sir Holbrook Gaskell was a chemical industrialist in Widnes, Lancashire, England.
Henry Brunner was an English chemist.
Winnington Hall is a former country house in Winnington, now a suburb of Northwich, Cheshire, England. It is recorded in the National Heritage List for England as a designated Grade I listed building. The building is in effect two houses joined, an older modest timber-framed house, and a newer, more elegant, stone house.
Charles Wigg was an English manufacturer of chemicals in Runcorn, Cheshire, England. After working as an export agent in Liverpool he joined with two managers of a Runcorn chemical factory to build what was initially known as the Old Quay Chemical Works, and later became Wigg Works. At first the works manufactured soap and alkali, but soon moved to extracting copper from pyrites ash, and later making bleaching powder and ferric oxide. During the later part of the 19th century it was one of the most successful businesses in Runcorn. Charles Wigg retired from the business shortly after it was taken over by the United Alkali Company and died eight years later. The site of the factory has been developed into a nature reserve called Wigg Island.
The history of Northwich can be traced back to the Roman period. The area around Northwich has been exploited for its salt pans since this time. The town has been severely affected by salt mining with subsidence historically being a large issue. A programme of mine stabilisation has recently been undertaken.
Northwich is a civil parish and a town in Cheshire West and Chester, England. It contains 35 buildings that are recorded in the National Heritage List for England as designated listed buildings. Two of these are listed at Grade I, the highest grade, and the rest at the lowest grade, Grade II; none are listed at the middle grade, Grade II*. The River Dane joins the River Weaver and the Weaver Navigation within the parish. Also passing through the parish are the A533 road, the Trent and Mersey Canal, and a railway built by the Cheshire Lines Committee. Many of the listed buildings are associated with these features.
The Statue of Ludwig Mond stands outside the entrance to Mond House in Brunner Mond Works, Winnington, Cheshire, England. Ludwig Mond was born in Germany but spent most of his working life in England. He moved to England in 1862 and joined the business of John Hutchinson in Widnes. Wishing to develop a better process for the production of alkali than the Leblanc process, he joined in partnership with John Brunner, who also worked for Hutchinson, to improve the ammonia-soda process, building a factory for this purpose at Winnington. In time the factory became the largest producer of soda in the world. Mond went on to work with other chemical processes, especially those involving nickel. He also became an art collector, bequeathing much of his collection to the nation. His statue was designed by Édouard Lantéri, and was unveiled by Brunner in 1913. It was moved in 1995 to stand next to the statue of Brunner in front of the offices of Brunner Mond in Winnington. The statue is recorded in the National Heritage List for England as a designated Grade II listed building.
The Winnington Laboratory was a former chemical laboratory at Winnington, near Northwich, in Cheshire, England.
The Buxton lime industry has been important for the development of the town of Buxton in Derbyshire, England, and it has shaped the landscape around the town.
