Fire Scale
Fire Scale is a standard color reference tool used in jewelry making to check the quality of precious metals, particularly silver, during the heating process. It helps jewelers determine the right temperature and heating time by comparing the metal's color to a set of sample colors. Think of it like a color chart that helps prevent overheating, which can damage the metal. This is important because proper heating affects the final quality and appearance of jewelry pieces.
