Working in copper at the moment whick I have not done before.
I imagine all of us jewellers are interested in different metals and how they differ from each other.
Today I learned annealed copper is very very soft but can be hardened considerably and a copper soldered join is stronger than the metal it self! I couldnt break it!

Copper is an awesome metal to work with.
I like copper. It’s a pretty color, and the various oxidation patterns are lovely. Glad to see you post this one.
Thanks for using copper. more videos using copper please for beginners, please.
copper is a pita to solder, lots of general heat but general heat makes it oxidize. and no amount of preflux is going to stop it. the best solution I personally have found: instead of using thick wire or pallions roll your solder flat, and pinch it like you would a platinum fusing. very pasty borax and flux liberally.. the heat from the metal must make the solder flow not the flame from your torch.
Aloha this beautiful morning from Maui 🌺, great to hear your voice again!
Another Maui person!!! Yay! Chris will be getting tan soon I think, with all the Aloha from Maui! 🌺
@@flyingcheff aloha, in Kihei
Hello!!
I gratefully receive all Alohas
I work 90% in copper. I make exquisite jewelry using copper. I say try it.
Copper is not a nasty dirty metal. It can get dirty like any other metal. Copper is safe and beneficial to humans. Plumbers do not use lead solder for plumbing lol. That would poison people. Copper is safe and beneficial to humans.
SO glad you're talking again! Great video!
He SPEAKS!! OH joy of joys!!!
Haha back in the saddle
I too was always puzzled about copper solder not being copper colored; my teacher always said just use silver. Recently I was making a couple of items in brass, and I questioned this once again (this time in Brass) with my supplier. To my surprise he sold me a solder paste that actually had a bit of gold in it to blend with Brass. Worked Great!! Now if we could find the same in copper we’d be set. Thanks so much for this.. sometimes the most insignificant things - have more to say then we realize. Keep them coming!!!!
Dip it in the pick with Stainless steel touching the solder joint for about 20 seconds & it will plate the solder into copper
I have practiced jewelry skills with copper. It works VERY similar to sterling silver for cutting, drilling, bending, soldering and casting. It is also a very stable surface for enameling (the melted glass kind, not the house paint kind.) There is actually a fair amount of jewelry products made in copper - what I refer to as "craft fair" jewelry, rather than the "jewelry store" level you normally work at. Copper does oxidize easily, but there are borax products that can keep the fire scale down. (Mix borax and alcohol and dip the piece in it before soldering.) But yes it does create fire scale quickly. It also reacts to the oil in people's skin and turns their skin green, so it works best for jewelry pieces that do not directly contact the skin, such as dangle ear rings that hang from a sterling ear wire, or pendants that hang from a sterling chain. But finger rings or bangle bracelets are going to turn your skin green. You can also use it to fabricate "master models" for lost wax casting, where you make a rubber mold of the copper piece and then use a wax injector to make wax copies in the mold rubber. Then you do lost wax castings of those wax models. Your master models cost pennies that way.
Is the copper solder any different than say regular piece of copper wire the same gauge? I am completely new to using a torch but I went to go melt the tips of a copper bracelet I made with some very thin (maybe 26 gauge copper wire) and not much happened the copper pretty much stayed in tack. What exactly does the flux do?
@@dharmakaya_handcrafts I just use silver solder on copper. It comes in hard, medium, easy, and each melts at a different temp. It does look silver against the copper color though.
hi, Chris, I don't know who taught you to use a file but before I started jewellery I did engineering and had my own trailer business but you don't need new files but you do need a file brush because the way your using it would clog it up a file only cuts one way and that is pushing it away from your self and when you pull it back you need to lift it so it doesn't clog up with small filling pieces plus you will find you do the job a lot faster. i do think you are brilliant but don't worry about people moaning your always get them thanks glenn
If you lift the file though you won’t file as straight and true. Just don’t put that much pressure on the back stroke.
@@jakeasinjake3347 but if it touching metal on the way back you are still likely to pick up a few fillings and when you push forward is when they go deep and clog the file I must admit you won't pick up so many but I was thought to get a square piece of metalmark a line around then put in a vice and with a black permanent marker couler the top and file it down to line once you've started filing just mark high areas only and I can file straight
I usually use copper brazing and not solder. It still looks about the same but the join is much stronger. The reason why copper solder or braze give a silver color is bcos of the zinc.
I have a copper brazing solder and its Cu + P solder. Can be used without flux (because of Phosphor content). I think It has about of 6 - 10% content of phosphor.
❤thank you for this video.
If you do it right, you don't need any solder or brazing rods with copper. In metal fabrication (high-school) we brazed two copper sheets together just by melting a copper puddle on the join and pushing it up the length of the join.
How do you mean? I’m nearly at playing. Please help!!!
thats called welding.
Your laugh is awsome

Flux stops the oxidisation and keeps the join clean and the solder will have a lower melting temperature than the metal
Thanks for uploading this video I enjoyed it I’m a big fan. May I ask a question did you quench the copper Ring while it was still hot ??
No I dont like quenching anything while its hot
@@diamondmounterbites8861 made a few copper and bronze rings now and find when I quench them hot it out is the chemical structure ie showing the solder mark more clearly. Great video thanks..
@@nickringastan7838 please re explain.. I didn’t get what you meant🤔
@@joyceeberner Hello. That makes no sense when I read it back, I’ve made a few copper and bronze rings now. When you solder bronze/copper then quench in cold water the the metal changes the chemical structure, thus changing the colour of the metal and making the solder joint stick out more. All ways cool naturally I never quench. Hope these make more sense. Nik
Looks like its a copper phosphorus solder. Im just interested in something thats much in colour.
Did you actually mean "tension" when you were referring to the tweezers holding the ring? In my mind most of the force would be compression with maybe a small about of angular force translating to a bit of tension towards the top of the joint?
Wow the noise from the insects at the start was wild! Lol thanks Chris for sharing as always
Edit.. Ps (plumbers) they use lead solder when solder copper so maybe that's what u got mixed up with or heard.. I did this with my very first ever ring i made an used industrial solder, then I got thenreal stuff months after when I got the bug an never looked bk☺️
I read somewhere it gets copper colored when slightly reheated after soldering…
If you are making a peace that you intend to make a mold of then copper workes fine. Looks like you are using 40% silver brazing wire. 10:27 Supervisor is always looking over your shoulder.
transformed a ring into a pygmy crown :D
What you've got looks like silver solder. I've soldered copper all my working life as an electrician always a white solder. Steve...
I enjoy a bit of electronic work. As a hobby I used to make portable stereos.
@@DiamondMounter back in the 70s' I took two mono phonographs, often Danset record players ripped the simple electronics out of one, mounted it in the other four wires from the pick-up, two to each, mount the board and speaker and you had stereo sound. Very cheap to do, a fiver for the second Danset and you were done. Steve...
How to make copper solder?
I dont know!
@@diamondmounterbites8861 i have a jweller frnd who knows about copper solder... I will let you know
nice.
just FYI, there are a LOT of brazing alloys...
en.wikipedia.org/wiki/List_of_brazing_alloys
that is phospher bronze brazing rod you just used..... yes it is much stronger than copper itself but will leave a silvering finish yes, a good joint and you dont see it at all though.... made many a celtic weave ring with it but need to be careful as it can flow like crazy and ruinn work pieces....
The good thing about the brazing rods for copper is they fill gaps very well.....
I join with silver but it don't look invisible
Yes silver works well on copper and brass
Silence was not golden Chris ;)
I made a chess set once, one side in silver and the other in copper. I had the silver side rhodium plated and the copper side rose gold plated (to stop the pieces tarnishing)
I wished I had made both sides in silver. The copper side was a killer to work on. Many bad solders needed re-doing and it was so hard to clean it up at the end. I just used silver solder too.
You butcher the English language with your non pronunciation of the letter "T". Apart from that, I love your videos, thank you :)
Bore off!
Sorry. Not impressed. Im new and I've seen much better. Good luck learning.
Are you for real?
