- 1). Purchase a silver testing kit. It will include a nitric acid-based solution, which creates a surface reaction when applied to silver. Ouicktest and Troytest are two manufacturers that retail silver kits.
- 2). Choose an inconspicuous spot on the item. It should be an area that is hidden or not easily seen. For items, such as tea pots or plates, simply turn them over and use the bottom area. For jewelry, choose a spot such as the inside of a ring, or the back of the clasp on a necklace.
- 3). Scratch a spot on the area with a small needle. Some silver kits may include a needle. The tip of a safety pin or other small sharp object will also suffice. You must make the scratch deep enough to obtain accurate test results. Generally, it must reach slightly underneath the surface of the item.
- 4). Apply a drop of the nitric-acid solution to the scratched spot. If the item is sterling or pure silver, the nitric acid usually has no affect on it. If it is plated or has minute traces of silver, the acid will turn brown, green or change colors.
