What temperature does silver solder melt?
Alloys commonly used for electrical soldering are 60/40 Sn-Pb, which melts at 188 °C (370 °F), and 63/37 Sn-Pb used principally in electrical/electronic work. 63/37 is a eutectic alloy of these metals, which: has the lowest melting point (183 °C or 361 °F) of all the tin-lead alloys; and.
"Soft" solder is a tin-based solder. Because it melts at a low temperature, you can apply soft solder with an electric soldering iron or gun. Warning: If you use a tin-based soft solder on a piece of sterling silver jewelry, you will never be able to use a torch or hard solders on it.
- Part 2 Joining the Silver
- Clean the silver.
- Apply flux to the joint.
- Position your silver components to be joined.
- Position the solder onto the joint.
- Heat the objects until the solder melts.
- Dip the object in water, then immerse it in a pickle solution.
- Rinse the silver.
- Soldering with a propane torch is the easiest way to join copper and brass. You can even use solder to join copper or brass to stainless steel, you just need the proper flux. But there are a couple tips to keep in mind to make it work right the first time: Use a liquid flux instead of a paste flux.
- As an alloy of copper and zinc, brass is compatible with copper, and manufacturers produce many common plumbing fittings with the material. Solder adheres as well to brass as it does to copper, so the fittings are usually molded with slip joints so you can solder them to the pipes.
Many metals used in jewelry making can be soldered, including sterling silver, fine silver, brass, copper, gold, and gold filled. Soldering creates a bond that, while not as strong as a fused joint, when cleaned and finished properly, is virtually invisible.

- Real 925 sterling silver jewelry typically has certain marks on it to indicate its purity. These marks include "925", ".925" or "S925", to represent the 92.5 percent pure silver that exists. If these marks are not present, it doesn't necessarily mean that it's not sterling silver.
- So the answer to the question, “is 14K gold better than 10K, and not as good as 18K” is both yes and no. Lower Karat jewelry may be more durable but higher Karat may be perfect for the right piece. It's up to you!
Therefore, if jewelry is made of silver or gold, it has to be torch soldered. Successful soldering requires heating the metal pieces, not just melting the solder, so if the piece is very large or thick, it's probably torch soldered as well. We recommend a 60-watt chisel-tip soldering iron.
- Solder with a higher gold content is stronger, but takes more heat to melt. It is recommended for joining two pieces together. Use "plumb solder," "medium" or "hard" solder, or solder with 14 karat and above. Solder with a lower gold content will melt more easily, and is recommended for small repairs.
- Actually, the hand feels cold because the heat from your hand is leaving your skin and moving into the ice. This is why the ice melts. This is one of those “duh” questions. If you apply heat, the molecules absorb the energy from the heat source and become increasingly energetic.
- When water freezes it gives up some of the water's energy. This energy that is given up is the latent heat of freezing. When the water was freezing latent heat of freezing energy was being released. Heat energy was actually being released.
