A saltcellar is a decorative vessel, made of glass or metal, used on the table for holding salt. In period, it was blazoned a “covered salte”, and was depicted with the salt spilling from either side, to help distinguish it from a cup; such “shedding salt”, even though part of the charge’s definition, was nonetheless explicitly blazoned. The illustration shows a covered saltcellar shedding salt, taken from the arms of the Worshipful Company of Salters, 1530 [Bromley & Child 214].
