Soda ash, Solvay style

In the 1880s, cost estimates for Leblanc soda ash production were 70% greater than the Solvay method production. By 1890, the Solvay process had come to dominate the world's alkali production. 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.
