More Valuable Than Pirate Treasure
H.H. Dow had dreamed of using the ocean as a mine since 1924, but it wasn’t until January 21, 1941, that it became a reality. That was the date the first ingot of magnesium made from seawater was poured in Freeport, Texas – and the first time man had successfully mined the ocean for metal. The new plant almost immediately began making a major contribution to the Allied War Effort and the production of lightweight aircraft. Later named DOWMETAL, Dow’s magnesium became an important product for everyday uses in automobiles, tools and toys.
In 1941, Dow began “mining” a new silvery-white treasure from the sea: the desperately needed magnesium for building airplanes.
