DescriptionLot-9432-22 (23224490453).jpg | Lot-9432-22: Sulfur, Scare In World War I, Is Plentiful Today. Although not generally know, sulfur is one of warfare’s vital elements. Indispensable in the manufacture of explosives, it is also a component of sulfuric acid, which is one of the important wartime chemicals. Unlike the condition prevailing in World War I, when a shortage of sulfur, due largely to the lack of improved mining facilities, was a threat to the Allied war effort, the element is plentiful today. One of the world’s richest single sources of Sulfur is the stratum in Louisiana and Texas, on the Gulf Coast of the United States. Shown: Forcing super-heated water into the stratum, some 1,500 feet underground, to melt the sulfur is the first step in mining. This bank of gas-fired boilers furnishes the hot water. Office of War Information Photograph, 9-15 April 1942. Original photograph is small. (2015/12/18). |
