I know there was a recent thread, where jasoninsd was involved with about ways to patina copper. I just spent over an hour trying to find it with no luck. Could anyone point me to that thread? I need to patina some copper jump rings for a necklace ASAP. Think that Liver of Sulphur is best, but am wondering if there is anything else I could use to get a quick patina. Pickle juice? I saw an TV program where pickle juice was used to patina a copper roof for a remodel. it turned out amazing. Thoughts? Thank you. |

Beth, I've never used pickle juice, so I'm not sure how long that would take. Liver of sulfer takes just seconds and is my go-to patina. I have heard gun bluing also is excellent for copper and the results are really pretty, but I've never tried it. It's on my list to get if I ever remember to stop at a gun shop and buy it.

Yep, nasty smelly old LOS is the best quick solution. There are some others that are just basically paint, hever tries them. Antiqued some sterling with bleach in a class once, but don't know what it does to copper.

You can also use hard boiled eggs to patina copper. There are several different methods but an easy one is to smoosh the egg in a sealed bag with the copper.

LOS works best for a dark patina. If you want other colors they have some stuff at Joanne's, Hobby Lobby etc. That work well

Thanks everyone. Will avoid the LOS for now. Never heard of the egg trick before.

Thanks everyone. Will avoid the LOS for now. Never heard of the egg trick before. You'll want to use a very small container to contain the gas. |

Hey Beth,
I don't know how quickly you can get your hands on Liver of Sulphur, but if you can get it quickly, the process to patina really is only a matter of minutes...

I saw an TV program where pickle juice was used to patina a copper roof for a remodel. it turned out amazing. Thoughts? Thank you. Years ago I built a custom table for a customer and they wanted some copper accent pieces with a green patina. I soaked the pieces in a mixture of sawdust, white vinegar and salt. Worked great. I have read that you can use potato chips instead of the sawdust if you do not have any. I bet you could just use the salt and vinegar but back then I had so much sawdust in the shop I was looking for an excuse to use it anywhere I could. Just keep in mind there are a lot of finishes that get lumped under the "patina" umbrella when deciding what method to use. The term is used to describe anything from a slightly darker than new finish to darker antiqued all the way to green/blue finishes. |

No egg trick yet. Need to get some eggs and try.
Currently have some soaking in pickle juice, but am not seeing any results yet.

fernwood Beth, don't know if this works on copper, but it works on brass. Messing with antique oil lamps I've had to darken up a piece of replacement brass at times. Old timer in the business told me to put it on the stove with the burner on high and it will darken like a tarnish very fast. Try one jump ring and see if it will work.

Also the tubs he uses (similar to Hillshire Farm Deli meats) have become my standard shop container for cabbing. Great for keeping orders separate, clean and protected. Easy to stack and sort into as well.

I want them to look anything but shiny, if that makes sense. The clasp and some beads are medium brown colored copper.
brown, blueiish or green colored would be fine.

I was taught bronze sculptors used uric acid to get that traditional green patina. In other words, they pee'd on their statues ... and that way developed deep bonds with their work.
