A bucket of salt

A bucket of salt

This worker in a dairy factory is about to tip a bucket of salt into a large butter churn. At the time, in 1947, salt was added to butter at a rate of 1.5–2% by weight. Before refrigeration, salt was an important addition: salted butter lasted much longer than the unsalted variety. In 2005, blocks of butter still had the same percentage of added salt. The dairy industry remains a heavy user of salt, mainly in its butter and cheesemaking processes.
