In this video, Prof. John Ahr demonstrates how to apply a peanut oil patina to your copper projects. If you've ever seasoned a frying pan, you'll have no problems mastering this simple technique. If you have a peanut allergy, consult a doctor before performing this technique.
You can use this patination approach to either give your copper pieces a uniform warm brown color or an interesting splotchy look. The best part is that this patina is pretty stable and doesn't easily wear off of jewelry objects.
All you need to create this finish is a heat source, peanut oil, a paint brush, tongs, and a quenching bowl full of water.

as always so appreciate your expertise and generosity! Thank you!
You're very welcome. I know that you're really going to like the peanut oil patina. Be sure to experiment with it. Light heat produces a golden color. A bit more heat makes some really pretty shades of brown.
Thanks for your support! : )
Thank you for this information. Great presentation.
Hi Shelley, I'm glad that you enjoyed the video. If you want to see other peanut oil coated copper pieces, check out the OJA's Instagram account. You'll see that you can produce a more golden or honey color finish.
Thanks for your support! : )
that's an Awesome technique
thank you for sharing
BENTLEY GT Glad you found a new technique to try. Thanks for watching! : )
Thanks for the video
Glad you found it helpful. Thanks for watching! 😀
beautiful patina.
It really is a beautiful patina. And, you can achieve to many variations depending on how hot you take the oil.
Thanks for your support! : )
OnlineJewelryAcademy I can't wait to try it.
Thank you!
👍🏼
Thank you
Glad you enjoyed the video Scoot.
Thanks for your support! : )
Being my favourite jewellery channel (college and uni courses are SO expensive unless you are a school leaver who is going into the jewellery business) I appreciate your videos greatly. I recently found another gold/silversmith channel which is really good, obviously you are still my favourite but I thought you might like to have a look at Andrew Berry (At the Bench) a lot of it is still beyond me but I thought you might like to know that you seem to have started a trend! best wishes xx
Hi Foxiepaws, I am familiar with Andrew Berry's videos. I don't know if the OJA started a trend. But, I will say that I believe we have gotten a lot of people to consider the use of peanut oil patina on copper.
Thanks for your support! : )
Love it..........Thanks.
Glad you liked the video. I recommend that you experiment with the peanut oil patination technique before applying it to your work. Since I made the video I have used this patination technique on a number of items. I'm happy to report that it is possible to achieve a nice variety of colors depending on the amount of oil on the piece and how long you heat it.
Thanks for your support! : )
Thanks !!! I will try.....
Now that is something I haven't tried in all my years working with copper. It looks beautiful, I am a jewelry artist but am actually doing research on copper sinks since mine went awry. Now I have to remove the ugly mess of a "patina" off the sink and then find a product to seal the sink. Maybe I am crazy but me using wax on the sink didn't work out. Perhaps it was too late in the game. Regardless I need to re-patina the sink and I feel like this method could be used. I love the results above... Anyone see a reason I shouldn't go for it? (after practicing on scrap copper first of course hehe) ... This is going to be used for certain on my foldform cuff bracelet, really this is such a beautiful warm color (I just hope my cat doesn't attempt to lick off the peanut patina before I get it sealed ;p haha)
thank you for taking the time to share this method with everyone, I greatly appreciate it!
Hi Jae, I'm glad that you enjoyed the video. I recommend that you do some experiments with the peanut oil before you go for it on your sink. You can get a wide range of looks depending on how much heat you use. And, you might want to perform some tests with water and cleaning products. Good luck with your project. I remember someone posted a comment a while ago saying that they had used this patina on the copper gutters on a home. So, you aren't crazy.
Thanks for your support! : )
This is genius
Glad you enjoyed the video. I encourage you to practice and experiment to learn how to control the color. Thanks for watching! 😀
Your 'make your own tools' videos have been wonderful so I just wanted to know if a ceramic tile is ok as a heat resistant surface? I re purpose everything I can lol!
No. A ceramic tile is not a great heat resistant surface. It can break due to heat shock. The best surface is either a ceramic kiln shelf or a cement board.
Thanks for your continued support! : )
OnlineJewelryAcademy Andrew berry said that kiln shelves absorb too much heat..I think I may go with the charcoal blocks I own an awful lot of trees so I don't find it unsustainable what with the number of trees we have had blown down the last few years. ..I think I will have charcoal til the next millennium lol!
Foxiepaws ACAnderson I’m not sure it’s polite to compare what one teacher says against another on a public platform.
1. Do you apply additional patinas to this for a mixed palette? And is there an order since this one is heat applied. 2. Do you apply something overtop to preserve that peanut oil (thinking renaissance wax) 3. If you selectively applied the peanut oil, in areas not oiled, if undesired firescale build up, can you spot apply pickle?
Hi Stephanie, You pose some very good questions. Peanut oil produces a range of colors from light golden brown to a dark brown. The color that you get depends on how much heat you apply to your piece. Think of it like the oil residue left on baking pans. You don't need to apply anything over it. Applying Renaissance Wax wouldn't hurt it. And, it would probably extend its life. If you dab on the oil and apply heat you'll get a mix of black oxidation and patches of glossy brown. It sort of looks like seraffito on ceramics or enamels. I have never tried to "spot apply pickle" but I'm sure it can be done. I recommend that you experiment and make the process your own. 😀
Does the effect need to be sealed to stay like that? If so, with what? Thanks!
Alice Ryan The peanut oil patina doesn't really need to be sealed. It is pretty stable. But, if you want to seal a copper item to keep it from oxidizing, you can use lacquer that has been thinned to the consistency of water. Just dip the item and dab away the excess. Or, you can find a plater in your area that does "e-coating". Thanks for watching! : )
Nice! will this work on brass? and any way to make darker patina?
This patina works best on copper. But, I'm sure you'll get an interesting result on brass. To make the patina darker just heat it a little longer.
Thanks for your support! : )
Thank u... :)
Can i use Sunflower oil for this? Wil the oil also protect my piece to avoid tarnish the copper?
Diana Ewert Hi Diana, I've never experimented with sunflower oil. Try it. But, be aware that it might not work as well as the peanut oil. The oil treatment will be very stable on your piece. It can, however, wear off with time. And, the oil treatment looks very similar to the natural brown color that copper develops over time. Have fun with your experiments. And, thanks for watching! : )
Hello, I have a question. I acid etched a motto into a copper sheet and then polished it. Now I want to apply the peanut oil patina to it. How can I preserve the writing to stay polished, and the background to get this patina? I had an idea to colour out the outlines of the writing with a permanent marker and then paint the oil on the whole piece. Do you think this method would work, or do you have any better tips/ideas? Thank you.
CANADASOCCERMAN13 If your goal is to just darken the background, using liver of sulfur would be easier to control. Because you have to heat your piece to get the peanut oil to turn golden brown, you can anticipate the letters will oxidize (even if you are careful to keep the oil off of them). : )
@@OnlineJewelryAcademy Thank you for your fast reply.
Good Day,
I'm working with a large copper artwork- (10ft x 6ft.).
I'm applying an oil based petina on it.
How do I seal this to avoid oxidation?
The peanut oil patina shown in the video is similar to the oil residue that you find on old cookie sheets and other bakeware. So, it's fairly permanent and seals the metal pretty well. No matter what you do, copper and its alloys will always try as hard as they can to oxidize. So, I often tell students to just accept that the surface of your copper pieces is going to change over time. You could apply a clear sealant over the oil patina. But, the copper's finish will slowly shift under the sealant. Good luck with your creative pursuits! 😀
@@OnlineJewelryAcademy Hi, thank you for the reply.
I did see the oxidation returning even after I put a clear coat, I was just wondering if I did something wrong.
I'm thinking of stripping it again and applying the peanut oil then clear coating it again.
I'm feeling that its too soon to be seeing so much oxidation taking place (1 week).
I'm seeing a lot of green coming through, especially in the recesses of the sculpture.
Hi, have you ever experimented with this method on silver..? If not, do you have a specific method for silver ?
+Tae Ken Do
This is not a technique that is commonly used with silver. But, you could try it and see if you like the results. It's essentially glorified cooking residue. So, it's going to only produce a yellow to brown coating on the metal. There are other videos on silver patination in the OJA playlist. Have fun and work safely.
Thanks for your support! : )
Thanks, I'll take a look at them, appreciated!
Do you have any suggestions for copper sheet? I’m putting copper sheet backsplash in my kitchen,countertop to bottom of cabinet, and looking for a way to age the copper. I’ve experimented with a brown darkener but not crazy about results. My wife and I love the results your video shows. Any tips would be appreciated. Hope this finds you well.
Your idea for your copper backsplash sounds beautiful. I've never given a full sheet of copper a peanut oil patina. But that doesn't mean that it isn't possible. By the way, the results shown in the video are fairly dark. You can go darker or lighter with this patina. If done lighter it looks like gold. My best suggestions for success would be to 1) Practice with some smaller pieces of copper (They will also give you a color pallet.) 2) Use a larger torch. 3) Set up a work station that will help you to maintain overall heat. Good luck with your project! 🍀😀
Do you think this could this work for thicker copper pipe?
+charlie denny Sure. The amount of heat required to burn off the peanut oil is minimal. So, you shouldn't have any trouble using this technique on a thicker item. Thanks for watching! : )
Is there any thing like vegetable oil, or vinegar and salt that would work with a hairdryer? i am trying to add a patina to some pennies and i am having a hard time doing it at home
Here’s a link that should help: www.onlinejewelryacademy.com/copper-patinas-video.html 😀
hi brother , can i use these steps for clean coin ?
The Peanut Oil Patina video does not demonstrate techniques that could be used to clean coins. Metal is generally cleaned in a pickle pot or ultrasonic cleaner. The OJA has videos on these machines on its website at: www.onlinejewelryacademy.com By the way, it is my understanding that coin collectors do not like it when people clean old coins. They love the natural patina that forms on the coins.
Thanks for your support! : )
Afternoon I know this is an older video, but if this were used on a piece of copper pipe that I cut, and sanded to use as a plain band ring, will this process stop it from turning your finger green??
Hi Shawn, The peanut oil patina would shield your skin for a brief period. The best thing to coat the interior of a copper ring with is clear nail polish. Thanks for watching! 😀
Thank you for the fast response, I don’t have peanut oil on hand but my wife works with essential oil’s and has coconut oil, any chance that would work?
@@shawneberhardt9004 Unfortunately coconut oil won’t have the same effect. The good news is that you can get peanut oil at most grocery stores. Be sure to practice with some clean copper scraps. You can create everything from a golden tone to a deep brown. Good luck and have fun. ☘️
Ok I didn’t have a chance to stop and grab a bottle and was hoping to finish it tonight…. I’ll grab some I have a few scraps on hand to test with I’ll send a pic of the finished piece once it’s done. Thanks again for all the help
Hi John, I'm an artist and designer. I have a project with copper panels 27" wide , 26' high, .008 thickness, glued to single pieces of plywood 1/2" thick. I would like to try your process to get an aged look for copper. I don't want the dark brown penny look, I just want a nice soft orangey, very light brown because that's the look of an old range hood in the bar.
1) can the burning process be achieved with a construction heat gun instead of the torch ( safety concerns and a way to control the heat on that size panels, 7 in total.
2) I'm intended to protect the finish, if I can get the appropriate look, with a Two Part Solvent Urethane Resin in spray. The burning won't disappear with that coating. Your advice please
Hi Romeo, the peanut oil patina can produce a beautiful golden color. If you look at the OJA‘s Instagram, you will see images of bracelets treated with the peanut oil patina that have the gold and orange color. I’ve never tried using the process with a heat gun. I believe that it will work with a heat gun. But, you will have to experiment to be sure. I believe that using a sealant to coat the finished pieces should work. And, it shouldn’t change the color of the finish. But, you will need to experiment to be sure before you start on your project. Good luck with your creative pursuits. And, thanks for watching!😀
Is this safe for people with peanut allergies to wear , many thanks Simon
I don’t know. But knowing how serious peanut allergies are, I wouldn’t risk it. There are warning on food containers that inform consumers that the product was packaged in a facility that also packages peanuts. 🧐
@@OnlineJewelryAcademy
Thank you for your reply, I will not use this , and I will look for an alternative
Thank you Simon
will it work with silver
Richard Hankins Hi Richard, Unfortunately, this oil treatment really only works on copper. You can experiment and try it on silver. But I predict that you won't like the results very much. Have fun with your experiments. And, thanks for watching! : )
Can another oil be used?
Hi Barbara, The reason why peanut oil is used is because it doesn't smoke very much and doesn't easily catch on fire. But this process is very similar to the oil build up that you find on baking pans and cookie sheets. So, you could experiment with other oils and see if they produce nice results. The peanut oil can make a really beautiful golden surface finish on copper at a low heat. Or, it can create various shades of brown. Have fun playing with this process.
Thanks for your support! : )
Can you use olive oil?
No. Olive Oil has a higher smoke point and doesn't behave the same way as peanut oil. : )
...'maybe' suggest they HAVE to use safety precautions. [ Edit....consider the flashpoint of oils, you don't want to make a substance combustion mistake and seriously have a relevant fire extinguisher available ]
Hi Christopher, The OJA encourages viewers to always exercise good judgment and proper safety precautions. And, we have a number of safety videos included in our playlist. While we appreciate your suggestions and concern, we will not be editing this video. Should we reshoot the video we will attempt to include more relevant safety information.
Thanks for your support! : )
Okay, sorry. I did not see the other videos. My friendly worry was if someone viewed this as a very entry level enthusiast not knowing correct process...I don't think you need to re-edit the video, but when using heat and combustibles perhaps having additional warnings information relating the subject might be useful.
Thanks again for your concern and support.
Have you ever run into any problems with this method for people with peanut allergy?
Thankfully I have never had a problem in my classroom using peanut oil to create a patina. But, I do let students know that it's in the room and I always announce when it's going to be used. Great question.
Thanks for your support! : )
Would olive oil work too?
+Carley Knight Art
I've never tried it. Why don't you try an experiment.
Thanks for watching! : )
It's been six months and you probably know by now if you tried it. Just in case, I want to point out that olive oil has a much lower "smoke point" than peanut oil. That is, it will start to burn much quicker and will smoke up in just a few minutes. This is why peanut oil is popular in high-heat wok cooking (it has a very high smoke point).
Observe the appropriate cautions in your experiement and let folks know how it worked out.
Hey repairmanjackX, Any cooking oil will produce a result similar to the peanut oil. But, the peanut oil is the best choice because it is thicker and coats the entire surface longer. This allows for a more uniform result. What you're really doing with a cooking oil patina is applying cooking oil residue to your piece to color it.
Thanks for your support! : )
don't dispute it, just pointing out that olive oil burns at a much lower temp than peanut oil.
