About Table Salt
Salt refining became industrialized in the 19th century. Iodization of table salt began in the United States in 1924 to address widespread goiter caused by iodine deficiency. Today, iodized table salt remains the most consumed salt globally and is one of the most successful public health interventions in history.
Best for: Baking (precise measurements), Canning, Pickling, Iodine supplementation.

The ancient Hallstatt salt mines in Austria, operational since 1500 BC, gave the nearby town its name (Hall- from the Celtic word for salt). Rock salt deposits exist on every continent and range from a few meters to thousands of meters thick.
