Items marked with “Gero 90” indicate a specific type of silver-plated flatware and hollowware produced by the Dutch company Gero. The “90” signifies the grams of pure silver used in the electroplating process to cover a base metal, typically a copper-nickel alloy. This measurement refers to the amount of silver deposited over a defined surface area, providing a durable and aesthetically pleasing finish. A serving spoon bearing this designation, for example, would have a silver layer equivalent to 90 grams per a standardized plating measurement during its production.
The use of this designation provides consumers with an assurance of a certain level of silver content and plating quality, distinguishing it from items with thinner or lower-quality silver plating. Historically, this type of plating was valued for offering a balance between the appearance of solid silver and the affordability of base metals. The markings became associated with durable and presentable tableware, popular for both everyday use and special occasions. This plating allowed more people to have access to silvered products while retaining the beauty and perceived value of silver.
