Mechanochemistry: The Science of Crush — Google Arts
The field was eventually named "mechanochemistry" by Wilhelm Ostwald in 1891. A Cornish Crushing Machine Worked by a Steam Engine from "The Playbook of Metals" (1862) by John Henry Pepper Science History Institute. Crushing remained essential for preparing materials during the 1800s, but research into mechanochemistry waned.
