The most astounding thing about copper? It’s essentially ageless. In some cases, you can scarcely tell old copper from new copper. So, while stone sinks from the 18th and 19th centuries most certainly show their age, even the oldest of copper sinks are Benjamin Button-like in appearance. And it gets better: In addition to not aging, copper actually grows better with age and the more it is used the faster it will re-patina.
