Silverware marked by the St. Louis Silver Company and bearing the term “quadruple” indicates a specific method of silver plating. “Quadruple plate” signifies that the base metal received a particularly thick coating of silver during the electroplating process. For example, a teaspoon bearing the St. Louis Silver Company mark and the term “quadruple” would have a substantially more durable silver layer compared to pieces marked with single plate.
The significance of this plating method lies in its enhanced resistance to wear and tear. A thicker silver layer prolongs the lifespan of the item, delaying the exposure of the underlying base metal and thus preserving the aesthetic appeal and value of the piece. Historically, quadruple plating represented a higher quality standard, offering consumers a more durable and long-lasting alternative to less robust plating techniques. This method was frequently employed for items intended for frequent use, like tableware.
