How Gold-filled Is Made
Gold-filled is made by fusing a layer of karat gold to a suitable supporting metal (or alloy), using equipment that carefully controls heat, pressure, and time. The bond produced is a permanent one.
Next comes a series of rolling operations, which compress the strip into a sheet. Repeated rolling reduces the thickness of the material in such a way as to preserve the proportionate thickness of the gold and the supporting metal. Repeated rolling also serves to increase the density of the gold, so that it becomes harder and more durable.
