Patination of sterling (NEW pics included)

Jewelry

I just read an older blog entry about patinas and there were some comments about sterling and the general idea that one could really only get grey to black. I'd like to share a different perspective.

By varying the concentration of the LOS mixture and also the temperature of the mixture, one can get reddish colors - brown, and also blue to purple. Adding ammonia helps achieve the brighter blue and purple color. Here is a picture of sterling done in this manner: Here you can see some of the different colors. From red, to blue and the irridescent quality.

 

This is the after pic (after about 7 mos in a drawer, NO sealant on it)

its definitely lost a bit of color...If I had sealed it with wax or krylon I think it would look almost identical.

 Here is the reverse side with no flash on camera:
 and the back 'after' picture:

(retained more of the color)

This pendant was colored using day old LOS soultion that had faded to a weak yellow/straw color. To that I mixed straight ammonia. I painted the room temperature mixture on with a papertowel very lightly, wiping dry, then applying more,then wiping dry until I achieved the colors I wanted. The nice thing is if you go too far you can take it off and start again. :)

How stable are those

How stable are those Janice?

We found we got some great purples on bronze from some dish soaps when cleaning after polishing but they only lasted a few days.

Gene, I believe this still

Gene, I believe this still looks the same some 7 months later.....I'd have to double check to be sure.

Sometimes I will spray a thing coat of Krylon over things that are patinated....or use Ren wax. . . but I think this is pretty stable. There is no flaky surface like happens with some verdigris type patinations. I think its safe to say its fairly stable.

I'll try to find this piece tonight and rephoto it so we can all get a feel for any change. :)

Very nice patination,

Very nice patination, Janice! I'll be very interested to see how stable it turns out to be over time. Keep us posted, please.

Thanks Rich! I didn't get

Thanks Rich!

I didn't get a chance to root around for this piece last night but I am sure I'll get a chance this weekend...weeknights are hectic as a single mom!

Really nice, Janice. I am

Really nice, Janice. I am wondering what LOS is. You have a very nice body of work from what I have seen here. I still neeed to get to your web site, but I am impressed at all I have seen.

LOS

I'm betting on liver of sulphur... Hmmm Brad


Janice Fowler's picture

sorry!

LOS = liver of sulphur. I understand it can be bought in chunk form or liquid - I buy it in chunk form. thanks for the compliment on my work. I really appreciate the feedback and encouragement!

I used liver of sulphur in

I used liver of sulphur in the past but have switched to lime sulphur from garden centers. It stays good longer. It is liquid and in a bottle so instead of lumps, use drops. No matter how hard I hammered the lid down on the little tins or how many plastic baggies I used, liver of sulphur goes bad on me.

Never heard of that Marilyn.

Never heard of that Marilyn. I have a little container of chunk LOS that I"v ehad for a few eyars - still works great. . . I can't imagine I'll need to buy any anytime soon as this seems to be the never ending container!

patination and longevity

the piece looks great .
here is a quick question.
when you are doing a more verdigris type patination and you get this incredible white/green patina how do you stabilize that with out wipping it away or darkening it???

I think that all you can do

I think that all you can do is to spray it with Krylon or some other clear coating. Just applyling wax will remove a lot of it. I don't like lacquer finishes because they can peel off in spots and prefer a wax that wears away in a more gradual fashion.

I agree with Marilyn

I agree with Marilyn although I've used wax a bit on some verdigris type patina...rubbing very softly with a wax that is soft and I usually rub it between my hands first to get it really silky soft.... or I use krylon spray. If you use Krylon, from what I understand it should be used in VERY light coats in sweeping motion, then let drym, then another coat, let dry, etc - building up 5 or 6 or 10 coats. Whichever protection you use, it will change the look of the patina of course - it will change the way light reflects from it, so doing some test pieces and keeping them on hand is a good idea.

Right on

Total agreement..many many light coats best approach I ve had. The pcs I'll post tomorrow use this approach. Brad

Bumping this up

I added recent pics of the same piece. There is, of course, some difference in the actual photography. . . but you can get an idea of the change. The front of the piece has lost some color, some of the loss is seen as areas that are more yellowed than red..the blueish areas still look pretty good, though some of those have turned more to a grey. I think if there had been sealant on here it would still look pretty good. The back retained more of its color - it was probably backside down in the drawer and didn't get as much exposure to the air...?

wax

What type of wax do you use and how do you apply the wax ? In particular how do you get it into crevices and wipe it off.

Regarding the Krylon, is that clear spray paint ? If so, do you spray it over stone and / or gold accents ?

I like to use Renaissance

I like to use Renaissance wax which is clear. It takes very little to cover metal although I bought my can in a woodworkers store. Before I had this wax, I used Johnson's Paste floor wax. The amber color didn't seem to matter even on silver. I do not put it on stones nor do I use the sprays.

Wax and krylon

I use various waxes - Renessance (sp) wax gets a lot of good feedback from people. I've been known to use candle wax...I basically take a bit of wax and work it in with my fingers...the heat of my hands helps work it in.

For krylon I use matte or clear depending on what look I want. BOTH will change the way light reflects off the piece so that needs to be taken into consideration. I spray prior to setting my stones. I don't think I'd have a problem spraying it on gold but I might consider taping those areas if I don't want them hit with it.

Gorgeous!

Janice,
Absolutely gorgeous!
I'm just beginning with my metalsmithing/silversmithing.. and the one thing that I have learned more than any other thing is just trial and error!
Great thinking!

UV Sealants

If you check out some of the book preservation sites and document preservation models you will find that you can get or make a 100% UV protective coating that will keep your item sealed and colorful for a long time to come. I am just changing my interest over from ancient books and manuscripts and book binding and preservation to making jewelry....(mid-life crisis without the Corvette!)...and am finding that there are a lot of similar thoughts on the construction and preservation and even 'false aging' of these items.
Thank you for sharing this because so often we see silver as a boring 'shades of grey' world where people shun it due to it's reputation rather than valuing it as one of the rarest metals on earth (fast becoming more rare than gold)
