Iron instruments similar to waffle irons, composed of two palettes that come together with the aid of two handles acting as a lever; designed to create Eucharistic hosts for Christian liturgies. A Christian symbol is typically engraved in the iron bed and stamped onto the hosts. Early examples produced hosts of around one-fourth inch thickness; later examples produced wafer-like hosts. The existence of host irons is established as early as the ninth century, although the earliest surviving example dates to the twelfth century. Seventeenth- and eighteenth-century host irons have been preserved in large numbers, and are quite similar to those now in use.
