The Natrona Alkali Company was incorporated to hold title to 1,600 acres of sodium carbonate deposits in Natrona County by the descendants of chemist, Lammot du Pont (1831-1884), who developed B blasting powder, using Chilean sodium nitrate and had hoped that the sodium carbonate might become a substitute for imported sodium nitrate in the manufacture of explosives, but the deposits turned out to have no commercial application. The Natrona Alkali Company records are primarily the corporate records related to a second incorporation of the company due to a clerical oversight, the materials date from 1950 to 1980, though there are some documents from the ealier company.
