How can I make beautiful black patination on copper?

2006

We make decorative laminate sheets by using high temperature & pressure.
We have also aluminum foil in our range.
The sheet size is 2440 x 1220 mm. & the thickness of the foil is from 100 to 300 microns.

Now, we want to start Copper foil in our range with patination process.

So, here I have a question that how can I make Black patination on Copper?

If I make the foil embossed & there are some deep are in the sheets & I also want to make black this deep area by patination.

You are requested to give an answer as soon as possible.

There are countless letters in the archives describing patination methods and recipes. Try the search engine using the terms "black" and "copper".

Good luck.
