The process of artificially aging sterling and fine metals to give them an antique or tarnished look is achieved through controlled oxidation. For example, immersing a silver item in a solution of liver of sulfur will accelerate the natural tarnishing that occurs over time.
Creating an aged aesthetic can enhance the perceived value and character of a piece, adding depth and visual interest to its surface. Historically, it has been employed to mimic the appearance of age on newly crafted items, providing a sense of authenticity or highlighting intricate details and textures.
