While assembly can be lots of fun, there’s something special about creating your own customized jewelry components. You feel a sense of accomplishment and pride when you wear jewelry you hand-crafted.
I want you to be able to experience this joy as soon as possible and with minimal investment, so my first project in this segment is…
‘Painting’ with Liver of Sulfur Patina
Liver of sulfur is a stinky chemical that is traditionally used to ‘antique’ or darken a silver or copper piece of jewelry. It is common practice to submerge the piece in a warm solution until it becomes completely dark (not quite black) and then buff off the high points to enhance the contrast and show off depth in a design. But when you slow the process by using a weak batch, you can view the color changes that happen as the patina process progresses. You can capture the beautiful bronze hues on copper by sealing them with a clear coating to make intriguing jewelry components.
I’ll show you my process and discuss various tips and techniques to get fabulous results. But first, you’ll need a ‘canvas’ to paint…
The simplest way to create a custom component is to start with a basic shape. In the jewelry world we refer to pre-cut shapes as blanks. So if you’re shopping, you would search for copper blanks or silver blanks. Just be aware that these blanks come in various thicknesses. There’s a wide array of shapes available in 24 ga thickness which is a great weight for earrings. (I’ll talk more about what gauges are appropriate for other types of jewelry soon.)
For metals we measure thickness using an American Standard Wire Gage for Non-ferrous Metals. Click here to learn more about this tool and how to use it.
Some blanks come with pre-drilled holes and the edges are all smooth making the piece ready for surface treatment. Others need holes added. Punching your own holes can be nice because you get to choose where and how many. I personally find myself attracted to classic shapes, which can be hard to source, so I provide copper blanks that I design and cut using my bench shear. You can click here to take a look at the pre-cut blanks I offer for sale. Because my blanks are simply cut shapes, they require filing and sanding to fully prepare them for use, so I am going to start by explaining how to properly prepare a piece of metal to be transformed into a unique piece of jewelry.
How to Prepare a Copper Jewelry Blank…
There are 3 steps for preparing a copper blank: punch holes, file, and sand. Here’s a video to get you going…
Click here to watch the video I mentioned about how to properly set up your hole punch pliers and learn more details about how I use a grinding bur fitted in a pin vise to debur the holes you punch.

Interested in taking the art of “painting with patina” even further?
Welcome to the
Colorful Copper Earrings Mini-course!
While I demonstrated how to use liver of sulfur for bronze color patina in the previous video, this mini-course builds on that information. It offers a more project-based, step by step instruction to create a pair of colorful copper earrings using liver of sulfur patina. I guide you through the process for 3 various approaches to create beautiful patinas that look fabulous without any other adornment.
I’ve created written instructions that provide an overview of the process for you to download to keep in your Jewelry Classes with Jen Reference binder for easy access. Plus, there’s a selection of project sheets you can download to execute designs I have mapped out for you. It’s kind of like a paint and sip project only you’ll be making jewelry.
Get started by watching the introduction video which describes what you can expect and how to navigate your way through the course…
If you are new to making jewelry, once you are ready to begin this project, you can expect it to take 2-3 hours to complete – although everyone is different. I highly advise watching through the videos before you start gathering your materials, tools, and supplies to familiarize yourself with what is needed. Have fun!!!

Materials you’ll need to make the colorful copper earrings you see in this course…
- Copper Blanks 2″ pentagon shape – 24 gauge
- Ear Wires – Lots of people have a sensitivity to copper, so I do not recommend using ear wires made from actual copper even if you coat them. I like the copper-colored niobium ear wires made by TierraCast. Niobium is a hypo-allergenic wire that they color using an anodizing method. You can find the ear wires through Lima Bead.
Click here if you want some copper test strips like I used in the course.
Alternate options for your copper blanks…
- 24 gauge blanks are available through a wide array of jewelry supply sources. They are often listed as stamping blanks. I have found shapes I like at Lima Bead, SJ Jewelry Supply, Stamping Out Loud, and even your local craft store with a jewelry section may have some. And of course, you can check out what we have to offer here at Jewelry Classes with Jen.

Additional tips and considerations for achieving great results:
There have been a few questions asked since I created the Colorful Copper Earrings Mini-course, so I am sharing the answers here in hopes of helping you if you come across the same issues.
Simply click on the + sign to access the answers to the following questions:
My marker doesn't come off when I wipe with alcohol, how can I remove it?
I have not come across this issue myself. But, I have only tested the use of Sharpie brand markers to mark my metals. They happen to also produce an industrial strength marker which is more resistant to the alcohol, but I generally just use the traditional fine tip or the ultra-fine tip black markers.
This doesn’t mean Sharpie markers are the only option you can use. But, I would suggest that you color on some copper with the marker you plan to use for the project to test if the marker comes off with rubbing alcohol before you go to the trouble of applying it as resist and getting the patina you want, only to then discover it doesn’t come off with alcohol. All is not lost in this case. However, you would need to sand off the piece completely, re-scrub the surface with the Bar Keeper’s Friend and then the Dawn and start again with a marker which does indeed come off with alcohol.
I am not getting the colorful hues, just the copper tones... what am I doing wrong?
Before we discuss possible technical issues, are you letting the piece dry to be able to see the colorful hues? When the blank is still wet, the colors are often not developed. Wick away the excess moisture and allow them to air dry. If you are still not achieving colorful hues soon after the initial color changes, you can read on …
There are generally 3 different factors that could cause issues with achieving the color hues that appear before you get to the copper/bronze tones when dipping pristine copper into the patina bath:
Factor 1: Is your copper really properly prepared? The cleaner the surface of your copper, the more even and colorful results you will get. The preparation process is intrinsic to getting nice even coloration with a broad spectrum of colors.
However, as I mention in the course, if you are using option 3 where you are going for dark accents, you will not be able to get the colorful hues because using the marker as a resist does not leave a pristine, well-prepared surface on the copper. Therefore, you can only get the copper and bronze hues along with the dark accents.
If you feel you really did a great job with preparing your copper blanks, then there are other factors that come into play…
Factor 2: Is your patina bath too strong or too hot? The bright colors develop before the rich copper and bronze tones. So, if you only get the copper hues, it could be that the patina mixture is too strong, therefore the coloration happens too fast and you bypass the rainbow hues in the first dip and swish.
There are two ways the patina bath may become too strong. A drop of liver of sulfur is not an exact measurement by any means. Sometimes a drop is tiny and another time it may be more of a small dollop, so there is room for error even if you follow the guidelines I present. There’s also cause for variation in strength due to the temperature of the water used to mix the patina. The hotter the mixture, the faster the colors change.
You can bypass this issue by using a strip of copper to test the strength of your patina bath just before you are ready to dip your prepared pieces. If it’s too strong, you can simply add some additional warm water. Test again until you are happy with the rate of the color changes. If the bath becomes too weak, you can add another drop of liver of sulfur. The idea is to test the patina just before you dip your jewelry components so you can adjust it as needed.
Still having troubles?
Factor 3: The quality of your water can cause issues. I live in Arizona. Our water here is quite hard, and I have not come across much of an issue. But I have heard from others who have experienced water supply quality issues wreaking havoc with patinas. The good news is, you can bypass this issue by using filtered bottled water or distilled water to mix your patina.
Should I add salt or ammonia to get more brilliant colors when using liver of sulfur?
I have not personally experienced a distinctive increase in brilliant coloration by adding salt or ammonia to my liver of sulfur patina bath when working with copper, especially once I seal it. However, I have seen great results when working with highly polished fine silver such as jewelry made with precious metal clay.
Some people add the salt or ammonia right into the patina bath, and some dip in salt water or ammonia before dipping in the liver of sulfur patina bath. There is no harm in experimenting for yourself.
The art of patina is a very difficult technique to achieve the same exact results with repetition. Just keep in mind that the color hues are going to change when you seal the pieces, so even if you get a more brilliant color before the protective finish is applied, you may not be able to tell afterwards. You are likely to have more fun if you just go with the flow, unless you happen to enjoy the process of trying to control all the multiple factors that can sway the results.
The lacquer spittled when I sprayed my pieces outside. What would cause this?
The short answer… it was too cold outside. Cold temps are not something I usually have to think about since I live in the desert of Arizona, so I had not experienced this issue before.
Luckily, the effect of the lacquer spittling when it was sprayed on the copper pieces with patina caused a textured finish – almost like a batique effect. But the uneven spray of the Nikolas lacquer was due to the cold outdoor temperatures. There’s a range of temps listed on the can for proper use.
The big lesson here is to read and follow all of the instructions on the protective coating you choose to use.
