Patinating copper plating





October 24, 2008

Greetings,

Will copper plated objects patinate? I was told that because of the plating process, the copper surface will not patinate as readily, if at all, as do solid copper objects (flashing, pipes, etc.). Can this be true?

My best,
Ken

Hi. It probably depends how thick (and consequently pore-free) the copper plating is. If you eat through it, it won't work. Pennies (post-1982) are copper plating on zinc and they color pretty much the same way copper pennies do, but are much more subject to severe corrosion.

As Ted has mentioned, depends which kind of copper you are using as well as which kind of additives you are using for copper plating.
