This material, also known as German silver or alpacca, is a non-precious alloy composed primarily of copper, nickel, and zinc. The designation referencing a city in South Yorkshire indicates a historical connection to manufacturing practices once prevalent in that region. It was often used as a base metal for silver-plated items. Tableware and decorative objects were common applications of this practice.
The significance of items manufactured using this method lies in their combination of affordability and aesthetic appeal. By employing a less expensive base metal and subsequently plating it with silver, manufacturers could create items that resembled solid silver pieces but were accessible to a broader market. The identification of pieces connected to a specific location signals a legacy of craftsmanship and trade associated with that geographical area.
