Don’t you wish we all could hammer that fast in real time. Lol

I think as it ages it will be even more beautiful. Thanks for sharing.

The ring looks really good, nice job man 🙂🙂

Absolut beauty!

This will look really cool as the galvanic activity starts to etch the borders, itll be interesting to revisit it in a year or two

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.

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.

Any tips on knowing when to reheat your metal to prevent cracking?

@mokumegane

It is important to get a feeling for the different material combinations. When the material becomes spring hard is a good time to soft anneal it. With silver & copper, the son is reached at 25% conversion. I really go by feel.

When twisting and bending by hand you can feel the metal start to "creak" as it crystallizes and starts to fracture.. while hammering you might be able to listen to the change in pitch and feel the difference in the recoil as the metal gets harder.. it's so much down to experience and learning how the materials work. You can really see how springy it gets when he's rounding it.. and that's some great precision hammer work!

Hi, excellent work👍🏾. Can you tell me what is the tool called you used to twist the copper silver bar once out of the rolling machine. Regards Damien

Question: At 7:26 couldn't you pass a metal nail file between the two joints to get the thinnest joint possible or do you need a rough surface for the solder?

@mokumegane

Жыл бұрын

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.

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.

@@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.

@@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,...
