How to solder gold chain

For connecting links of a gold chain you will need special solder. Measure on Apothecary scales approximately 58 parts by weight of gold, 11 parts of cadmium, 12 parts silver, 19 parts of copper. Prepare of these substances solders by mixing particles of metal in the vessel of a suitable size. When soldering gold, use flux is not required, because the metal oxide does not form.

Fasten the chain links in a miniature tisochki. If your goal is to connect the ends of the broken link, pass through the two adjacent link of the Golden chain needle, awl or knitting needle. Now gently grab the link of the tweezers, squeezing it so that the ends of the element closed.

Warm up the soldering torch or a heated soldering iron. The soldering hold the solder while continuing to gently heat the soldering area. The hot mixture will be spread along the seam and hardens, securely connecting the ends of the link.

If soldering, excess solder, carefully remove them with a small pliers. Now with a needle file, fine cut, handle seam, to give the product a more perfect look. This treatment formed fine gold dust and metal dusting. Collect these wastes, if necessary, to be used subsequently for the preparation of solder, if there is a need for a new repair of jewellery.

If you have to solder a chainconsisting of very small links, use a special technique of soldering with phosphorus. Mix prepared according to the above method, the solder on castor oil, adding the mixture of phosphorus. Dip the chain in the resulting composition. Solder will fill the gaps in the links, subject to connection. Now, roll the product in talke.

Thus treated chain skip carefully through the flame of a gas burner. Phosphorus in the gaps will instantly burn out of flares, efficiently cook links.
