Ways to Test Antiques and Collectibles With a Black Light
Many antique lovers use long wave black lights to date objects and test for authenticity. Some clues to age or telltale signs of repair aren't easily visible to the naked eye but will be thanks to fluoresce under ultraviolet light. While it's not the end-all answer in antique authentication and dating, it is a very good place to start. Hard-paste porcelain should fluoresce a deep blue or purple color, while soft paste will glow white. But before buying or selling a nice piece of porcelain, always take it into a darkened room with either a handheld or keychain black light to test for repairs.
