Adding Patina to Metal Jewelry
Creating a Patina on Metal Jewelry
As a jewelry maker, I have found that there are many different ways to add a color patina to my metal creations. It is a relatively easy process, and there are new products being introduced all the time to make it even simpler. This article will discuss the different methods that are available to get those different color patinas on metal pieces. Some of these methods use common household supplies...even food!

Liver of Sulfur for a Dark Patina
When using liver of sulfur on sterling or fine silver I can get a range of different color depending on how long I leave my jewelry piece in the solution. Liver of Sulfur comes in rock or gel forms. I dilute or dissolve the liver of sulfur in warm water, add my piece to the solution and watch the changes. The best way that I have found to control the color is to dip the metal in the solution until it gets to the color I would like to keep, then dip the metal in ice water to halt the color changes. Early on the metal turns a yellow to a brown, more dipping creates a blue/purple color and then finally a deep dark gray/black. I then use a polishing cloth to bring back the highlights of the metal. Liver of sulfur can also be used on copper and bronze but the color changes are not as varied as with silver.
See picture of ring below for a sterling silver piece that was oxidized with liver of sulfur patina.
I like the gel form of liver of sulfur. It is easy to dissolve and I waste less.
Gilder's Paste for An Easy Patina
Using Gilder's Paste on metal is as easy as rubbing on this wax based product and wiping off the excess. This is great for textured pieces where the recesses can grab onto and hold the patina. I've used a sealer over the top of some of my pieces, but I've also left it as is with great success. Click the amazon link to see the other suggested colors available. See key below for an example of Gilder's Paste in Patina.
When I do custom stamped work on stainless steel or other base metal, I will use the black gilder's paste to bring out the stamped impressions. It works well for this application. See photo below.
The key in my introduction photo has a patina made with Gilders Paste in Patina Color. Many different colors of Gilders Paste are available.

Creating a Heat Patina
I like creating a heat patina on metals. I've found that the best metal to add a heat patina to is copper. I can get a wide range of color from pinks, oranges, red, blues and purples with a small butane torch. All I do is heat my copper piece with a torch, pulling back every few seconds to see the colors that develop after the copper begins to cool. I stop when I see the colors and patterns that I like develop. I've also started using a heat patina on my bronze clay work. I use the Goldie Bronze product and I can get some nice deep bronze coloring from heating it up a bit. I then polish the high places to get a great contrast with the patina.
Keeping the rainbow colors in the copper is a bit of a challenge. Currently, I use Protecta-clear to protect the metal from tarnishing and darkening the color. Sometimes though I lose the blues and purples when I use a coating. Those are the color ranges that are hard to keep.
The earrings below are made of copper and given a torch fire patina and coated with Protecta-clear.
Protect the Patina
Many of the patinas that are natural can be delicate. Protecting the patina has been a trail and error adventure for me. I've used many different products to help seal the patina on the metal. Renaissance wax and Protecta-Clear are two products that I've relied on in many instances to give me a natural finish that is not glossy or fake looking, but still give my patinas the protection that they need. I use the Renaissance wax on those pieces where the patina is not as fragile and can take the buffing that is required after I apply the wax and let it dry. I use the Protecta-Clear in the spray form for those pieces that will not hold up to rough contact.
