How to patina new zinc sheeting and make it look old/antique

What does one use to patina new zinc rolled sheeting and make it look like weathered zinc (blue-grey in finish)? I am an artist who currently works with copper patina, but would like to begin to work with zinc. I would be so grateful for any information.

Thanks!

You can use 200 gm iron chloride/1 lit water solution (cold immersion,cca. 20 min.)!Good luck!

Thanks Goran,

What does " cold immersion cca 20 minutes " mean?

Thanks!

1.I don't know which degreaser you use-you can use acetone [linked by editor to product info at Rockler] or pure alcohol!

2.cca 20 min=approximately 20 minutes.

Good luck!

We are building a new home and have built a bathroom vanity out of wood which we covered in zinc. We ordered the zinc from a metal company. It came in a sheet and we sent it to a sheet metal company to cover it. I now have it ready to install, but it is still brand new and shiny. I know it will age with soap and water over time, but I want it to age now. What can I use to expedite this process?
