This German chemist said this about sulfur in 1843.
“It is no exaggeration to say, we may fairly judge the commercial prosperity of a country from the amount of sulfuric acid it consumes. (Sulfur’s price affects the price of…) bleached and printed cotton stuffs, soap, glass, etc, and remembering that Great Britain supplies America, Spain, Portugal, and the East, with these, exchanging them for raw cotton, silk, wine, raisins, indigo, etc, we can understand why the English Government should have resolved to resort to war with Naples (in 1839) in order to abolish the sulfur monopoly, which the latter power attempted recently to establish.”
