But it wasn't until 1872 when Ludwig Mond licensed the Solvay method that the technology was introduced to the British Isles, the center of world soda ash production thanks to the Leblanc process. Mond was born in Kassel, Germany, in 1839, and studied chemistry between 1855 and 1859 under the noted German chemists Hermann Kolbe and Robert Bunsen.

The Solvay Process, named after its inventor Ernest Solvay (1838–1922), aims at the production of soda ash (sodium carbonate, Na 2 CO 3), which is a major commodity and an essential raw product for many industrial applications (above all: the production of glass) and even used in applications (e.g. detergents).Thus, the Solvay Process is one of the most …
Pure soda ash is a white, water-soluble salt. Soda ash is added to glass because it lowers the melting temperature of silicon dioxide (the primary constituent of silica sand). Hence, soda ash is a flux—a substance that can reduce the melting point of another substance. A flux such as soda ash is required for making glass because the melting ...
Nearly half of the worldwide annual production of 56 million metric tons of soda ash, used in glass, chemicals, soaps, detergents, metallurgy, water treatment, pulp, and paper is produced by the classical ammonia-soda (Solvay) process. This process, which has been applied for more than 150 years, can be considered as a fully optimized process.
