A salt cellar (also called a salt, salt-box and a salt pig) is an article of tableware for holding and dispensing salt. In British English, the term is normally used for what in North American English are called salt shakers. Salt cellars can be either lidded or open, and are found in a wide range of sizes, from large shared vessels to small individual dishes. Styles range from simple to ornate or whimsical, using materials including glass and ceramic, metals, ivory and wood, and plastic.
Use of salt cellars is documented as early as classical Rome. They continued to be used through the first half of the 20th century; however, usage began to decline with the introduction of free-flowing salt in 1911, and at last they have been almost entirely replaced by salt shakers.
Salt cellars were early collectible as pieces of silver, pewter, glass, etc. Soon after their role at table was replaced by the shaker, salt cellars became a popular collectible in their own right.https://en.wikipedia.org/wiki/Salt_cellar
