In the days when keeping food fresh was a problem, spices such as pepper, nutmeg and cinnamon were used to enhance or disguise the taste of it. These were usually held in casters, so-called because they cast their contents over the food.
Since the early 18th century, the shape of the caster has scarcely altered. The early cylindrical and baluster shapes come with bayonet-type covers. These have two flaps that fit through wire at the rim and are turned to hold the lid in place. Octagonal examples appear in the reign of George I and after this time covers have bezels sitting inside the caster bodies.
Before about 1780 casters often came in sets of three: one with a large piercing for crushed loaf sugar; one for pepper and a third for other spices, or for dry mustard. In the latter case the caster would have a "blind" cover, without piercing. After about 1780 casters came singly or in pairs.
18thC casters are usually
marked in a group under the base. Some 18thC and 19thC
examples are marked in a line on the side of the body.
