Silver brazing<\/a>The soldering is a highly sought-after, frequent procedure in the jewelry industry. Only by soldering can a broken chain or bracelet be joined together, it is also used to make highly artistic precious metals<\/a>. For fans of silver it will be interesting to understand the process of soldering silver at home, the methods of carrying out this work.<\/p>\n\n\n\n

Silver and its properties. When soldering silver is necessary <\/strong><\/h2>\n\n\n\n

Silver<\/a> - is a \"white\" precious metal that is actively used to create jewelry. Its sacred properties have been known since ancient times, but it is its physical properties such as softness, malleability, and fusibility that have made it popular in the jewelry industry.<\/p>\n\n\n\n

When it is necessary to restore a broken piece of jewelry or to correct a deformed area, silver brazing is used.<\/p>\n\n\n\n

\n

Soldering silver is not only used to repair jewelry, but also to make new items or to update old ones. The 925 proof is taken as the basis.<\/p>\n<\/blockquote>\n\n\n\n

The necessary ingredients for how to solder silver at home  <\/strong><\/h2>\n\n\n\n

How to solder silver at home<\/a>? Soldering at home is quite possible, but you need to take care of special props, learn simple skills, also read the recommendations that will be presented in this article.<\/p>\n\n\n\n

You will need special tools for the work, which are easy to buy.<\/p>\n\n\n\n

Fireproof surface<\/h3>\n\n\n\n

The fireproof surface itself is a working platform for soldering. It will protect the room from fire, allow you to conveniently place the decoration, and then safely carry out all the work.<\/p>\n\n\n\n

\n

The surface can be made of asbestos board, it can also be a sheet of metal or workbench top.<\/p>\n<\/blockquote>\n\n\n\n

Soldering iron<\/h3>\n\n\n\n

As a soldering iron it is better to choose not a classic product for soldering black metal, but a miniature soldering iron, which is used for soldering chips. Its quality contrast<\/a> - small size of the glow needle, as well as light weight and fast heating.Otherwise, it is completely the same as the original product. It works from a 220V mains supply.<\/p>\n\n\n\n

Gas burner<\/h3>\n\n\n\n

The gas burner consists of a removable cylinder, which is changed when the gas runs out, a nozzle and a piezo element. When the button is pressed, pressurized gas is supplied to the nozzle and ignited by the piezo element.<\/p>\n\n\n\n

\"Heat-resistant<\/span>

The torch is needed to melt the edges of the silver jewelry, as well as to create a fusion area.<\/p>\n\n\n\n

Solder: what it is, types<\/h3>\n\n\n\n

Solder is needed to create a thin \"bridge\" of melt, which, when solidified, solders the elements of the jewelry. How do I solder with silver solder?<\/p>\n\n\n\n

For soldering silverware<\/a> As a rule, only silver-based solders with the addition of other fusible metals are used.<\/p>\n\n\n\n

\n

The silver content should not be lower than 70%, tin can be used as a filler metal.<\/p>\n<\/blockquote>\n\n\n\n

It is this composition of solder that ensures its strength, bonding to the base, i.e. to the jewelry, as well as strength and durability. The most commonly used solder grade is PSR-70, where 70% is the silver content.<\/p>\n\n\n\n

PSR-70 can be produced as a granulated powder, wire, short bar up to 3-5 mm, as well as in the form of a thin sheet with a thickness comparable to the foil thickness of a chocolate candy.<\/p>\n\n\n\n

Homemade and proprietary flux<\/h3>\n\n\n\n

The purpose of flux is to cover the damaged surface during soldering and also to keep it free of atmospheric air or moisture. Now you can buy flux readily available at any store that sells locksmith supplies. It is a whitish powder that is packaged in sachets.<\/p>\n\n\n\n

Flux for soldering silver with your own hands, consists of an aqueous solution with borax powder.<\/p>\n\n\n\n

Borax is a chemical, officially called \"sodium tetraborate. It is freely available in any large pharmacy, as it is used in medicine.<\/p>\n\n\n\n

How to make flux is the first step in the question of how to solder silver:<\/p>\n\n\n\n

    \n
  1. The borax should be poured into a metal container, you can put it in a saucepan.<\/strong><\/li>\n\n\n\n
  2. Pour distilled water (it must be unadulterated, simple boiled water will not do).<\/strong><\/li>\n\n\n\n
  3. The powder dissolves when heated over low heat.<\/strong><\/li>\n\n\n\n
  4. After dissolving, you get a homogeneous mixture, which should be cooled at room temperature.<\/strong><\/li>\n\n\n\n
  5. After cooling, the flux substance crystallizes at the bottom. The crystals have to be extracted.<\/strong><\/li>\n\n\n\n
  6. They are then ground to a powder into which water is added.<\/strong><\/li>\n\n\n\n
  7. The substance should be similar to gouache in consistency.<\/strong><\/li>\n<\/ol>\n\n\n\n

    Acid solution for etching  <\/h3>\n\n\n\n

    Acid for etching<\/a> is used to degrease surfaces for soldering. If the surface is dirty, the solder will not \"grip\" and the jewelry will disintegrate.<\/p>\n\n\n\n

    The most common etching liquids used are hydrochloric acid (HCl) or sulfuric acid solution (H2SO4). These can be purchased at specialized technical stores where solder accessories are sold.<\/p>\n\n\n\n

    Tools<\/h3>\n\n\n\n

    In addition to the soldering iron, solder, acid, you will need the following auxiliary tools than solder silver:<\/p>\n\n\n\n
