Silver-filled is a new layered metal, introduced during the surge of silver prices during the recession. Это не сплав, потому что содержание металла не одинаково на протяжении всего материала. Серебряный наполнен 5% или 10% sterling silver by weight, fused with heat and pressure to a brass core. Поскольку наполненное серебристым-многослойный металл, он не может быть отброшен. The silver layer thicker than silver plated, but this is still a much lower quality product than most solid silver alloys. Now that the price of silver has gone down, this metal is less common in the market. There is no legally approved quality stamp standard for silver-filled pieces at this time.
