Interpreting the Evidence
Women Bagging Salt
Suggested Teaching Instructions
Women put salt into small bags at the salt works in Piffard, New York, circa 1900.
Salt was commonly made by evaporating salt water from brine swamps and fields or by evaporating ocean water. In central New York, areas like Syracuse became major salt manufacturing areas due to their brine swamps. New York City also had a salt manufacturing industry due to its ocean locale.
The evaporation method for either ocean or brine water is similar. First, the water is gathered in large, flat pans. Then, depending on the method used, the water is evaporated by solar heat or by heating the pans with small fires. The salt can then be scraped from the pans and distributed.
