Its precursor was probably the sprinkle or castor: a small pepper box or ball often attached to the top of late 16th-century bell salts. By c. 1660 the free-standing form had established itself, appearing both singly and in groups of two and three. The domed cover is often pierced in intricate patterns, and the body is usually cylindrical, baluster- or pear-shaped. Its spreading foot is generally plain but may be relieved by such ornament as mouldings, gadrooning or beading. In the 18th and 19th centuries casters were incorporated into epergnes and cruet frames)

Some have a neck with interior threading for securing a threaded stopper or external threading for a screw cap; the cover is often of silver. Others are of one piece with holes in the domed top; these are often filled through a corked opening in the bottom. The holes sometimes of ornamental shape, vary in size depending on the intended contents. They are sometimes called a cruet or a sifter, sometimes, especially in the United States, the term is spelled caster)
