Hi Daniel. I would have assumed that aging of copper should produce a "green effect". See what I mean here.
It is most interesting that your aging fluid produced a brown effect on the copper plating which goes great with the color of the wood! I am glad to see that you have returned to the Bounty!
Heinrich, weathered copper has a brownish and green color. To get the green color is a complicated method that I was not willing to pursue.
On the other side I didn't like at all the brand new copper color.
I could have washed the copper with Cetone and wait 10 years to start to get it brown and a few more to get the green with the house humidity. Or splash it with salt water to accelerate the process a little bit. (See my cash register examples)
Instead I decide to weather it with a patina , as you can see, and then I lacquered the copper. It will stay as it is for MANY decades.
Let me provide examples, showing that you are correct and showing what I wrote.
First: The Constitution at Boston Harbour. See new plate added with tourist signatures beside the old ones. There you have the real aging, as you wrote.
Second: One of my NCR Cash Registers I cleaned the brass 15 years ago, but never lacquered. I was lazy that week . VS another one of my collection, that was cleaned and lacquered more than 30 years ago (not by myself).
See the difference in color. The brownish one was very bright .... 15 years ago.
Now watch this other one.
Not lacquered, BUT it was nearby one of my Salt Water (marine) fish tank and it got a few salt water drops by accident. I knew aboutvthe water drops when brass started to be green . Will be restore when I retired.
Bottom line, you are correct !! Greenish spots would be more real.
Cheers
Daniel
