One thing I found was that after the bluish patina was set and dry, I Q-tipped it with hydrogen peroxide resulting in interesting dark brown to black shades. One of them was hard and scaly, resembling oriental black lacquer. But nothing was predictable ahead of time.
That's very interesting, thank you for sharing it!!! Do you think this will happen on any blue?... Regardless of the substance used, ammonia, vinegar, baking soda...??? Also, this brown/black color appeared and remained after the hydrogen peroxide got dry?
@cuforming I don't recall what I used, but it's ammonia fumes with either a vinegar or ammonia bath sprinkled with salt. It could have been green or blue, and it was dry when I applied the peroxide. It's a small serpent on my wall. It's been awhile.
Thanks for your experiments! I personally love the soya sauce impact. Definitely have to try it:) I normally use vinegar or ammonia, but I put salt in the solution in the very beginning and spray the same solution on the pieces. Sometimes I heat up the jar to speed up the process. They give predictably green and turquoise respectively, but after spraying lack on the pieces, the color becomes almost the same:(
Thank you for your comment and appreciation. These experiments are just an example of how many things you can use to make patina on copper. I really would like to make a lot more tests and combinations of substances, time of exposure and methods. It's a big opportunity to discover new patterns and colors. Sadly, I couldn't find the best lacquer that keeps the original patina color, this matter needs a further research.
Muchas gracias!! Ha sido una experiencia muy formativa. Me gustaría que hicieras un video sobre opciones de laca para preservar las pátinas. He escuchado acerca de lacas catafóricas usadas en joyería. Sigue adelante jugando y aprendiendo.
Muchas gracias también por ver mi vídeo. No tengo experiencia con lacas catafóricas, será una oportunidad para probar algo nuevo. Mi protector de joyería favorito es la laca Zapon, que es excelente para la pátina del arco iris pero no es tan duradera como el esmalte cocido. Sería muy interesante hacer un vídeo sobre todos estos productos.
Great video! I've known about ammonia and vinegar patinas, but never thought to try soy sauce, I'm definitely going to do that. I don't think the rice experiment worked because the rice was cooked and already contained moisture. I would try uncooked rice so it soaks up the ammonia/patina solution like the woodchips do. I would also try putting a few pin holes when using a bag to seal pieces in patina solution. I believe that the science behind patina causes it to develop as the solution dries on the piece itself, which is why using fumes is so successful. Keeping the piece locked in a moist environment will not develop the patina. Try it out, let us know the results!
I'll make more experiments for sure, but I know for experience that cooked rice works, I just did something wrong with the one in the video. The variable that it needs to be changed is something else, not the fact that the rice was cooked. As you say, it must be an air flowing issue.
@@cuforming I think there is a video of yours that comments on how to calculate the area and electrical current for the process, as I am lazy and bad at mathematics, I am trying to find programs that can automate this work. What I found that might be useful, is a free program that measures areas using images. I'll leave you here the link to the program that might be useful, if you're curious to take a look. It's called "ImageJ" I lived in Japan for a long time, and I returned to Brazil, my home country with only 200 dollars in my pocket, I had a slave life in Japan, a lot of suffering, 26 years of life that wasn't worth it at all, and now I'm here in my country is unemployed, I have to make a difference with my last 200 dollars that I have left, and the only thing, the only way that I see now is certainly the Electroplating method, therefore, I thank you from the bottom of my heart for all the knowledge that you shared with the world.

Try hard boiled eggs. I've used them when I don't have any sulfur based patina around. Also, your times could be shorter. When I use liver of sulfur I get some nice reds when I soak them for a short time.
Thanks for the advice, but I have a lot of homemade liver of sulfur left from all my experiments, I don't know how eggs can be different, it's worth the try. Check all the video where I make it and test the patinas!
@@cuforming Eggs contain sulfur. Egg whites contain the most, but it's worth using the whole egg. I've used them to blacken copper and bronze. Some colors come out at different times in the process, so if you take your metals out of the patinas early, you may get different colors. Even how I've washed pieces prior to patina has made a slight difference in times and colorings. Please make a video if you try eggs. I'd like to see what you come up with in combination with the other elements you use.
@@64t120r I will definitely try eggs!!! Thank you!!! You can see all the color I made with liver of sulfur In almost all my videos and reels, go check them out.
I make at least a video a month. If you have any request about experiments related to jewelry making, chemistry and electroforming I'm opened to any idea.
@@cuforming To be honest, I have absoluely no experiences with everything connected to electroforming, I am just collecting stuff to be able to start it, one day. But the experiments you made are great. You could try citrus on the jewellery, Coca Cola and incence fumes, for example. Or hair dye, fish sauce or coffee.. the possibilities are endless. Thanks for your efforts and for sharing your experiences!
This kind of patina will usually get darker with a finish like varnishing. I'm not very sure about wax right now but, I think the color will be more subtle.
If you want a consistent and shiny green, you can use the electropatina solution to make it, the process is a little tricky, but after you gain enough experience with it, you will manage to make green and lot more colors.

Nice to display of patinas may I ask where you got that cool 3-D printed arrowhead design

Ty! Pretty cool - how safe are these techniques? Do you need to do them outside?
Thank you! It's all safe! Maybe you need to be aware of not breathing ammonia fumes.
Thx again! I love your channel ❤
I'd love to see even more experiments, this is very interesting

@@julianec8494 Hair dye contains ammonia, that can be interesting... also fish sauce could give nice results.
I wonder if a wax finish would retain the original colours ?
This kind of patina will usually get darker with a finish like varnishing. I'm not very sure about wax right now but, I think the color will be more subtle.
Try yellow mustard,/ammonia
You are not the first one telling me this... some advised to use ketchup, some mayo. It's gonna be fun!!!
@@cuforming I did two copper vases with yellow mustard and they came out amazing
@@thomaskuzia8125 I can't wait to try that!!! Thank you!!!
Hi✌️
Please help🙏, How to get a sustainable green color?
If you want a consistent and shiny green, you can use the electropatina solution to make it, the process is a little tricky, but after you gain enough experience with it, you will manage to make green and lot more colors. Check this video ruclips.net/video/M6U_wIUnH-E/видео.html to see what I'm talking about and if you want the recipe for the solution I have it in my shop: www.cuforming.com/tutorials.php
You printed these with a 3D printer?
I designed and printed them, ruclips.net/video/jNw5jXUmjl4/видео.html. I also have the STL file on my website www.cuforming.com/3dprintables.php
🤩
❤
Love your videos btw!!!
@@cuforming Thanks , love your copper art too :D
the oxide created by ammonia or vinegar is very toxic
That is the reason why I always seal it with varnish, even though the color changes
Can you please name this oxide?
Wear a mask and gloves
