Items marked with the term, as it pertains to the Barbour Silver Company, indicate a specific level of silver plating. The “quadruple” designation signifies that the item received a heavier coating of silver compared to pieces marked with lesser designations, such as “triple” or “double” plate. For example, a serving tray bearing this mark suggests a substantial layer of silver intended to enhance durability and resistance to wear.
This increased silver content provided several advantages. Primarily, it extended the lifespan of the plated item, making it more resistant to tarnishing and scratching. The heavier plating also contributed to a richer, more luxurious appearance, closely resembling solid silver. Historically, this characteristic made it a desirable alternative for consumers seeking quality silverware at a more accessible price point, offering a balance between aesthetics and affordability.
