Ácido nítrico 53%. A causa del cobre, primero se vuelve amarillo, luego verde y finalmente azul.

Yes, I used 16 layers here. One layer of silver is significantly stronger than the others. For rings made of gold, palladium and silver I usually use 17 layers.

Yes nitric acid, 53%. At the beginning it is of course yellow. Due to the dissolved copper it gradually turns blue from green.

Thanks! In German “Windeisen”. I don't know the English term.

Is a tap wrench, normally use for taps

Nitric acid. Due to the copper, it turns from yellow to green to blue. and there it is green right now.

Baldwins Patina

Pátina de Baldwin. Hay un enlace en la descripción.

Thanks a lot

too arrogant from ur part, no need to be if u are better feel proud but the others work its valuable too

No, it‘s different

Hello, this is Baldwins Patina

@@mokumegane muchas gracias

Danke. Das ist Salpetersäure.

Jeder fängt mal klein an. Ja das ist die basic Variante. Gedacht um Auszubildende die Grundlagen zu vermitteln. Kein Betrieb der Welt lässt seinen Lehrling gleich ein Meisterstück fertigen;) Sie müssen lernen das andere andere Ziele haben als sie selbst. Und versuchen die Dinge im richtigen Kontext zu sehen. Die Ronden kann man übrigens bei mir im Shop erwerben.

Not at all. We can separate and reuse it.

@@mokumegane Even if you can separate and reuse the chips (more work, more energy consumed) I would consider the amount of work and energy put into making the layered plate substantial and using more than absolutely necessary only adds to customer price. Still, this can be done without all the chipping. Make a small mokume gane bar, torque it, then use a chisel to make a hole and shape it on the ring mandrel.

@@torstenneuer1560 I see what you mean. In series production, it is essential to be able to produce a disc more efficiently from sheet metal. The chips and mold costs are irrelevant. My time is the expensive part. I make these discs for trainees. It is also important that each piece is the same size and weight. That's what customers expect.

Yes we do and ship worldwide. You can find some information on this at www.mokume-gane-shop.at. We can discuss your needs via email.

@@mokumeganeJust emailed:)

Tap wrench

Thanks. We make them ourselves.

Thank you very much! Yes, I etch with nitric acid.

Since my English is not so good, I use a translator. I'm not sure if I understand what you're asking. Do you mean the overlaps from twisting? If you structure a sheet too deeply, it can also be that the edges lie over it. looks like a crack but it isn't. You have to be alert and keep an eye on all of this.

@@mokumegane exactly. What's preventing moisture from getting into those cracks and forming a patina.

@@jmullens90 There are no cracks there. The layers are firmly and coherently connected to each other. In principle, a patina always forms when it comes into contact with atmospheric oxygen. That is also very desirable. But what you don't want is verdigris. It develops on contact with the salt of acetic acid.

Yes, I put it in the water right after the glow. I always forget to film that. It's such an automated action.

The blanks are produced on modern sinter presses. I work here with another company on the development of semi-finished products. Even if you only see me, it's actually a whole team that deals with it. If it turns out I'll make a video of it.

@@mokumegane oh okay, that's nice, but it would be nice to see how they welded the copper and the silver. Hot brazing? Or forge welding? But forge welding copper is quite a pain so seing the process would be super interesting

@@jeanladoire4141 Using diffusion welding. In German we say "bonden" to the process. The sheets come in a graphite mold and these are placed in a sinter press under a protective atmosphere. Here, water-cooled stamps constantly exert high pressure over several hours at the right temperature on the metal sheets. The sheets connect. A costly process, but with excellent results. This means that not only sheet metal but also powder, granules, wires,... can be processed. And also materials such as titanium, ceramics, glass,... For example, the ring blanks here are made of titanium and silver granules: mokume-gane-shop.at/collections/silber-titan-1/products/ringrohling-titan-silber

@@mokumegane impressive technology, i've heared of it used in aeronautics parts... So as i suspected, forge welding (the modern version of it, where the forge is replaced by a furnace, the flux by inert gas and the hammer by heavy presses). No wonder why the result seems flawless! Thanks for the info! I'm a bladesmith and i'm experimenting with a lot of new metallurgical processes (i'l trying to find new forms of damascus, kinds that have never been made yet). Do you think i can contact the engineers you work with and ask them about my project?

@@jeanladoire4141 Exactly. I'm the right person to talk to. For a specific request, please send me an email: [email protected]

Thanks. There are already customers who like to wear such rectangular ring shapes. But the reason I make the rings like this in the videos is that I just want to show the pattern making process. I manufacture semi-finished products from Mokume Gane and would like to give suggestions here.

It doesn't need a rough surface. The surface should be clean and the ends should be as close together as possible. But the solder needs a little gap to flow (capillary effect). But you can do that a little better than I did in this example. The soldering gap is a bit wider here than I would have liked.

@@mokumegane thanks!

Beautiful! What was it that you brushed on at the end?

@@joyceeberner I use this patina solution for quick coloring: mokume-gane-shop.at/collections/patina/products/baldwins-patina

The semi-finished products for sale are produced in large slabs on sinter presses. I would like to show in the videos what you can do with the already finished semi-finished products. Just as a suggestion. We manufacture panels of 150 x150mm. Also individually layered according to your needs: mokume-gane-shop.at/collections/massgefertigtes-halbzeug-neu You get a lot of rings out of it and that's why this process is not shown here. And not in all other videos either. Thanks for the input I will explain that in the future in the description. Here: kzfaq.info/sun/PLhm0YW70I3mgkDeYIRn0_xRl4yR-Y2_mr I show you in great detail how to weld Mokume Gane in a simple way. It's in German (since my English isn't good enough for that) but it should be okay with subtitles.

You can cut it open with a small cutting disc or diamond saw and water cooling. HSS tools like those used to cut gold rings will not work. Yes, it is generally not a good idea to wear rings that are too tight.

Ja fräsen geht sehr gut. Ganz klassich konventionell oder noch besser mit einer Kopierfräße und Schablonen oder mit CNC kann man sehr präzise Muster formen. Mit erodieren ebenfalls. Ich lerne gerade den Umgang mit den Meißel um andere Metallarbeiten ausführen zu können wo es das einfach braucht. Im Kanal von Ford Hallam kannst du hier einen Meister darin zuschauen.

Especially skin sweat is a problem here. Depending on the individual, it can be very aggressive and attack and eat away at the copper. I like to use Ag/Cu here because it is relatively inexpensive. And it is possible for me to demonstrate the possibilities of design. It is also a very good combination of materials to learn from. Otherwise, in the case of art objects, no change can be observed here, even after decades.

@@mokumegane yes, it's the sweat that provides the electrolytes to "power" the galvanic cell.. there are other Makers who have videos that explain the science and show the results.. An art piece will last, I'm glad because the forging is exquisite <3

​@@Faesharlyn I would like to learn more and understand the subject better. Can you link some of these videos that explain the metals/coats etc ? Thank you

@randomdyfbrn If you google Why you don’t want a copper and silver mokume gane ring It'll bring you to James Binnion Metal Arts, he wrote a fantastic explanation and you can decide from there where to look for more info if you like.

Danke! Generell verwende ich renaissance wax zum konservieren von Oberflächen von Buntmetall. Kupfer ist bei Schmuck so eine Sache. Je nach individuelle Hautchemie kann der Schweiß es sehr stark angreifen und regelrecht wegätzen. Das ist von Mensch zu Mensch wirklich sehr unterschiedlich. Zum Üben oder wie hier um einen Vorgang zu demonstrieren ist Ag/Cu jedoch perfekt. Es ist relativ günstig und einfach zu verarbeiten. Aber schützen tue ich die Ringe nicht weiter. Ringe werden auch sehr hoch belastet. Kommen ständig mit deutlich härteren Oberflächen und mit Chemikalien in Berührung. Da hilft sowieso keine Schutzschicht.

Danke für die super schnelle und ausführliche Antwort. Liebe Grüße
