rockbrain- it's been awhile. How are the colors holding up? Did you wax them?

rockbrain How are all your patina finishes holding up? I did a few around this same time frame and just noticed tonight that they have already changed! Granted, I do not have them protected in any kind of bag or anti-tarnish wrapper. They are just out in my studio but I’m surprised to see in just two months quite a change in color. I had started with a sort of deep copper/gray color and noticed today that they have really turned quite orange, kind of a brighter orange. I polished with a sunshine cloth and that calmed the orange back down a bit maybe closer to the original color but not quite as gray. I’ve been wondering if over time and multiple polishes if the patina ultimately goes away and you are left with bare clean copper again, especially if polishing is required every month or two. I have to wait for a lot of time to go by to see for myself. Also, my pieces are coated with Renaissance wax so I’m surprised even more to see such a quick color change. I'm surprised they would change that fast if you used Renaissance wax on them, but I also would not leave them out in the open. I'd at least have them in little ziplock bags to prevent air from constantly hitting them. The air is what causes the oxidation. Polishing them with a Sunshine Cloth will take the Renaissance Wax off of them evenutually and will also remove the patina on the metal. Sunshines Cloths do have an abrasive in them. |

hummingbirdstones Ya I was a bit surprised at how quick they changed as well. I was still working on the design and practicing which is why I hadn’t bagged/stored them. But also I think it’s good to know these things, how they will change over time. And, hmm, it sounds too like I might need to look for some other types of polishing cloths. I’ve always just had the yellow sunshine but maybe I should find some without an abrasive, I didn’t realize that was in there. Thanks!

The regular ones you can buy at any store use rouge. Sunshine also came out with a couple other cloths a few years ago. One is pink which is more abrasive and the other one is blue which is softer than the yellow and less abrasive. You might try the blue one. PM me your address and I'll send you one snail mail.  |

Also, my pieces are coated with Renaissance wax so I’m surprised even more to see such a quick color change. , I have *no* personal experience with this--I'm merely repeating what others have said. Several times I have read that Renaissance Wax actually attracts dust. If this is true, it likely would result in faster discoloration. I don't store in plastic bags (unless it's a gift for someone), but I keep my jewelry in a drawer that is primarily closed. I just took a look at some patinaed pieces that were done probably ten years ago, and although they could use a polish, they haven't darkened that much. And I stick my softer stones in my dehydrator on the "herb" setting (I think it's about 125 deg.) |

So I was re-reading through this post & have a question.
Why would you need to heat a stone, to drive the water out of it after patination,
if you are going to put the same stone in a tumbler with water in it ?
What am I missing.

I guess maybe I should have asked,
Why would driving the water out of the stone after LOS (or anything for that matter) be important ?
Wouldn't it just dry out naturally ?
Patty.... who just likes to understand things.

*Khara UPDATE: Last night I was taking a look at various recipes for using liver of sulphur and came across an article (which appeared knowledgeable) that said that if you use too much LOS in your water, it causes rapid oxidation which can easily flake or come off. Could that be your problem? The article said that your patina will last much longer if you use less liver of sulphur and repeat the process if necessary. I think I was following a link from Wikipedia (not sure). FYI, I use one to two drops of it in perhaps half a cup of water. I used to use one drop, but I have had the LOS for ten+ years (tiny little bottle) and it seems a bit weaker.

susand24224 Thank you for the info. I don’t think that’s my issue as I try to make my patina last and use only 1 or 2 drops in a small half pint glass, but this is good to know.

liveoak I don’t know either. rockjunquie mentioned liking to dry steel wool the wire wrap. I was thinking of trying that but haven’t yet. I’ve done my steel wool wet. I think I learned this years ago with metalsmithing, I don’t remember. As long as I let the steel wool air dry it seems fine but if you put it back in the bag it will rust. I feel like some others here also mentioned reasons for chasing out the water but my brain isn’t remembering them right now.
