Archaeological research in the town of Droitwich, Worcester County has recovered evidence of a pre-and early Roman salt industry. The salt extraction involved distinctive technological processes because of the strength and purity of the brine source. A common vessel found archaeologically is a tall, crudely made tapering jar with a small indented base. They are called briquetage vessels. The body is porous and thickly constructed from coils of poorly mixed clay. A consideration of the context of the vessels and requirements of the salt making process leads to the inference that they were used to dry the salt crystals after boiling of the brine.
