The molds produced in this manner could only be used once, which made them inconvenient for standard objects like handles and buckles. Permanent mold casting, an industrial casting technique focused on high-volume production, allowed smiths to reuse molds to make exact replicas of the most commonly used items they sold. In creating these molds and developing standardized manufacturing processes, silversmiths could begin delegating some work to apprentices and journeymen. For
