I hand patina all the wire that I offer on this website. The process is individual to the type of wire. I aim for uniformity but different rolls of wire may vary slightly in color. Also, I sell the wire in 10 ft rolls for easy in handling the wire and coiling it for sale.
I only put a light patina on my wire so that the rosary made will maintain some brightness while still matching the parts.
If you wish to remove some of the patina on your wire, swish it in vinegar and baking soda and then rinse in water. That tends to brighten it up a bit. But for my personal preference I rarely need to alter the wire after it is has a patina.
I hope that information is helpful.
