I am on a serious mission to refine techniques and learn new ones. This week I got to try something new on one of my most favorite things in the world to make (10 years and going strong) which are my copper rose sculptures. I developed a fast patina on the surface and then sprayed it with a clear coat to seal it so that it stays that way for years to come. Patination on metal isn’t new to me entirely but this was the first time I intentionally developed and sealed it on my roses. My results were great, I am so pleased, so I am likely to keep doing them this way.
To develop the patina quickly, I used acid to clean the copper and then left the piece out in the weather for a week. It was REALLY green at that point:
Not wanting it to stay THAT green, I wiped some of it off and then applied the clear coat. There are areas that are very green and areas that are natural copper colored. The heat of the torch during soldering also put a red patina on a couple of the leaves.
Also check out this copper rose dish that I did the same process on, only a little more mild.
