Wow. I don't know who you are but I am completely loving your scientific approach to patinas. Hugely helpful. You're also funny and you do great editing down so it's a pleasure to watch. Big fan. Thanks! Going to buy some copper right now for a 20x24 painting using your research. Wish me luck
Hello, An unsealed patina is often called a "living" patina... it will continue to change depending on the environment. It can rub off or be cracked if the metal is bent (although a sealed patina will also crack if the copper is bent). But where the patina comes off the copper will eventually change into a nice deep brown - complimenting the remaining patina. But, a stable patina will keep its colour for quite some time. Hope this helps? n.

Loving your content! It's helped me get a better understanding of patinas and why some of mine have failed in the past.
Thank you for the high quality free educational content! :)

What happens to patina if it is not sealed at all? Disappears or develops further? Let us know, pls.
