Paste Solder

by Kate Richbourg

If you use solder in your jewelry craft then you’ll need to be sure you have plenty of solder for your current project and future projects. We carry many different types of solder for many different purposes and different metals. Whether you’re looking for gold, silver, copper, pewter or aluminum solder, we have you covered.

Take a look at this quick video tip by Kate, as she shows us how to use paste solder.

Kate Says:




Types of Solder: (there are many more…)

Aluminum Solder, 7.1 Grams||SOL-820.21

Aluminum Solder, 7.1 Grams

A great new method for soldering aluminum, this paste melts at only 395 degrees Fahrenheit, far below the melting point of aluminum or any other metal. Capacity 7.1 grams.

Copper Bearing Solder, 14.7 Grams||SOL-820.41

Copper Bearing Solder, 14.7 Grams

No additional flux is required with this specially formulated paste for use with copper, brass, nickel or bronze. Contains no cadmium or antimony. Flows smoothly at only 430 degrees Fahrenheit. Capacity 14.7 grams.

Silver Bearing Solder, 7.1 Grams||SOL-820.07

Silver Bearing Solder, 7.1 Grams

This low-temperature, silver bearing solder paste will speed up soldering tasks because it works with the heat of a match or lighter. It will join 22 different combinations of metals. This paste includes an easy-to-use, no-mess, no-waste syringe. 7.1 grams.

Now that you’ve seen a just a few types of solder available and easy it is to use them – take a look at all of the Soldering Tools and Accessories available on our sister site JewelryTools.com. I’m sure you’ll find something you are looking for!

      Paste solder does not come in different thicknesses. It is a paste that comes in easy, medium and hard, just like sheet solder. That just refers to the temperature at which the solder flows. When joining metals in different steps, you always start with the highest flow temp first and work your way down as you add more pieces to your project. Hope this helps.

    I appreciate the information, but would have really loved to see her actually solder it. The way this video was finishe3d up it almost implied it would dry and be fine….did she use a torch? can you use a soldering iron?

      You use a torch with paste solder. Once it flows, it is just like other jewelry solder. I like it because I do not have to flux my pieces before soldering. As with all soldering, your metal needs to be clean for the join to be secured properly.

    Thank you for this information. I have a question about Copper Bearing Solder. It was specially formulated for use with copper but it leaves a silver color on the soldered piece. Does Kate have any solutions to this problem?
    Thank you for your time.

    Copper bearing solder, when used correctly, really is not a copper color but a darkened silver color, which blends better with copper. When heated too long after flowing, it turns more of a silver color. Also, if too much solder is used, it is more likely to flow away from the seam, creating grey solder flow areas around the seam. It is best to remove excess solder, but this is not always possible. Sometimes the excess copper in reused pickle “coats” the solder when you pickle each piece, which can make the piece appear like the solder was never there, especially after using LOS to patina.
    Your best bet when using copper bearing solder is to use way less than you think you need and immediately remove the heat when you see the solder flow.

      Thank you very much for your answer Judy. Home made copper plating solution seems to be the best remedy for the problem.

    I tried to give the solder paste many time with no luck. It always burns to ash. I have never gotten it to flow.

    I have watch several videos on copper solder paste and it looks so easy.

    Any tips that may help?

      I just noticed your question. Without knowing what kind of torch you are using and the size of your project, my answer is only a guess.
      If your paste solder turns to “ash,” it has not reached a high enough temperature to flow.
      If you are using a butane torch, it may not be burning hot enough. A butane torch burns hottest after filling, so I fill mine before I start a project and sometimes during the project as well.
      If your project is too large (over 1 1/2″) or too thick and you are using a butane torch, the torch cannot heat the metal up enough all over to “melt” the solder to a flowing stage. Using two butane torches at the same time can help, one used on top of the project and one from underneath.
      You might want to consider a different type of torch that heats up to more than 2450.
