apple_pie_order Do you enjoy polishing things a lot? Every day? Copper is high maintenance. You might take a look at traditional porcelain over cast iron. Or go to a high end kitchen shop and ask to see the differences between grades of stainless steel.
ASVInteriors If you are using a sink daily, you will find that it ages just like a stainless steel one scratches. Everything that is used earns its patina. It also depends on what each manufacturer will tell you: each have different compositions to stop them oxidising or they will eventually turn brown. I wouldn't dismiss it out right but I think first a bit of Internet research, answers from Houzzers and then some interrogation of a copper sink salesman will answer most of your questions.
Best of luck - love the idea of going different
Gabberts Design Studio You can get a granite sink that will never scratch or lose it's look. There are higher end versions, and then those sold at big box stores such as Home Depot. Go with the higher end quality.
If you choose copper, you'll find it is amazingly easy to maintain! Hammered copper is particularly simple since it doesn't show fingerprints as stainless steel or shiny copper does. For basic cleaning simply use a mild soap and warm water. Keep your copper product clean and dry by wiping it down after each use with a soft cloth. Harsh abrasives or copper cleaners should never be used on our products as they may affect the finish. For extra protection, a product such as Flitz Faucet Wax+ may be applied.
Uncoated copper has the added benefit of natural antibacterial properties - a big bonus in the kitchen.
