Soldering sterling silver?

Can you tell me what I need to solder sterling silver jump rings on a charm bracelet? A have a small soldering iron that I've never used. I don't know what else to get in terms of the kind of solder and/or what is needed.

I have a Weller 25 watt soldering iron that I was told is for craft/jewelry projects.

Any suggestions or advice would be much appreciated. Thank you!

    Sorry but a soldering iron does not get hot enough to solder sterling silver. They only get to 850 degrees or so. At that temperature the solder does not bond well and will eventually break. You need to use a torch to get it hot enough to open the pores of the metal to suck in the solder and bond. I just use a hardware store propane torch like plumbers use (about $15).

    If you don't want to learn to solder and make other things, I'd have a jeweler do it. If you do want to learn soldering, read on:

    Use a silver solder (jewelry grade, hard or medium) Flux it well with a liquid (spray it on) flux like Battens or or paste Handy Flux. Since you are working on a bracelet and jumprings, I would use a third hand to hold your item with the joint up for soldering (I do that to solder bails, jump rings, ect.) over a fireproof brazing board. Light the torch with a striker, adjust the flame to a fine tip and back it up 4-6" from the piece. Heat the whole piece with the torch and watch the flux. It will bubble and dry, then turn off the torch and place yout solder bits. Resume heating, then as the flux smooths out it will turns brown and the solder will be close to be ready to flow. As soon as it flows, remove the torch and drop the item in your pickle pot. (pickle is an acid solution that will remove oxidation and clean the joint. You can buy it commercially or get "ph down" from a pool supply). Only use copper tongs to dip things out of the pickle, rinse with water, file and polish.

    Soldering takes practice and when you are learning you usually melt a few things. (the melted bits become little silver balls to decorate other jewelry). Get some scrap copper from a metal recycling yard in your area and practice soldering different pieces together. You'll find out how much heat it takes and thicker metal takes more than thinner. Scrap copper flashing sheet is great for pendant backings and soon you be using the thinner stuff to cut bezel strips for mounting stones. It's a great inexpensive metal to learn on. Have Fun!

    How To Solder Silver

  • 1 decade ago

    Yes. Your iron is OK. But you need a small bit. If your bit is not interchangeable you will have to buy another iron with a fine bit. Your charms are sterling silver which means that you should use silver solder to mend it. Go to "Cooksongold.com" on line and buy Extra Easy Silver Solder Strip and some borax as flux.

    All this is going to cost you and needs a lot of practice so it would be more sensible to take the items into a jeweller and get him to do it. Or go to your local technical college or art school and get a student to do it for a pint or two. I do amateur jewellery and I wouldn't recommend that you do this without some practice as it is very easy to spoil the whole thing.

    well for me i use a much more higher wattage of soldering gun. i use a 40 watts or higher with a pointed end soldering iron to solder a broken silver or bracelet. before you solder apply soldering paste to the bracelet and heat the part where you will join the together, use a small soldering iron much smaller used than an electronic equipments, use a 0.05 soldering wire. apply the wire directly to the parts to be joined and , viola, but don't blow air or put it in a fan to let it cool after you soldered it afterwards,its a cold solder meaning it has brittle joining.you can confirm it because it will look like a light colored and not a silvery glossy joining. leave it naturally for its heat to dissipate. so good luck

    I suggest u take it to a jeweler, you would need flux and silver solder and then a buffing wheel after you solder, it would be much easier to have it done

    Pure sterling silver requires proper care and cleaning to maintain its initial luster and brilliance. Since its much softer than many gemstones, silver requires special precautionary methods to prevent damage to its texture and composition. The good news? Caring for sterling silver doesn't have to be a laborious, time-consuming task. As long as you store it properly and keep up with regular periodic maintenance to prevent the dreaded tarnish, silver cleanings can be quick and easy. When properly cared for, sterling silver jewelry like Pandora will look great for years to come.
