Dow Chemical Company
Dow Chemical Company focused on research, and soon was able to extract many more chemicals from brine. World War I provided demand that enabled its growth, because Britain blockaded the ports of Germany, which at the time included most of the world's largest chemical suppliers. Dow Chemical quickly moved to fill the gap for wartime goods, producing magnesium for incendiary flares, monochlorobenzene and phenol for explosives, and bromine for medicines and tear gas. By 1918, 90% of the Dow Chemical Company production was in support of the war effort. During this time period, Dow also created the diamond logo, which is still used by the Dow Chemical Company.
