Silver is very malleable and ductile, and as such is highly preferred by silver and goldsmiths to make money, jewelry. Silver craft takes years to learn as an apprentice to a goldsmith, or in school or university offering such courses. Perfection comes only with practice. However, the basic techniques can be learned by anyone with patience and the right tools!
Piercing: silver is cut to form a basic shape or to make a decorative pattern with a hole saw. When you create a pattern, a small hole drilled in the sheet silver to allow the saw blade to be positioned. The sheet is then attached to the drilling was under stress. Blades can be thick that allows rapid cutting or very good for detailed work. The leaves are delicate and can easily be broken. As such, the work must be done slowly. The blade is vertical and the metal moving slowly to make curves or corners. Blades are also lubricated by passing through the beeswax, which makes cutting smoother. The work is supported in a bank parity that is screwed to a workbench with a V-cut so as to support both side of the cut. Small chips of metal called Lemel collected under drilling leather in a cloth or paper, which is then recycled into new dishes.
Welding: silver pieces are welded together. Welding Silver, which comes in different alloy mixtures, mainly containing silver, is used for welding. Silver solder melts at a very high temperature and so a torch is used. The temperature required to melt silver solder is very near the temperature at which the piece you are working on it to melt. To manage temperatures, the work of the welding torch and is usually done in the dark for the color of the metal, as it is heated, can be used to measure temperature Part. Silver Solder come in soft, medium and tough on the earlier versions, higher and higher melting point. Multiple pieces which require the use brazing welding at first and work down, with the following welding degrees so that each and does not melt or distort the former. Welding lead should never be used as high temperatures cause the solder to run all over the silver, the damage and what is useless.
Annealing: The best part is working, the more difficult and more fragile it becomes. Repeated annealing silver remains soft, pliable and easy to work. It is made with a torch in the dark. Silver is heated until it gives soft red glow pink, which is the point just before the merger. The piece is immediately cooled in cold water which freezes the molecules in the lineup they were when almost melted, and therefore makes the job easier. However, working with a blowtorch fire leaves stain the silver is removed by pickling.
Stripping: Fire spotted silver piece is placed in a bath of acid, sulfuric acid, especially to remove any oxidation before working on it. Pickling salts are used for work performed on a smaller scale. The acid solution is kept warm to accelerate the process. The piece was washed with water, and pumice to remove any remaining dust.
Conformation: The work was finished form conforms in many ways, depending on the desired shape. Tubular shapes like rings and bracelets are formed in the cores that are held in a vice, while annealed metal is hammered with a wooden mallet or leather. Containers and other pieces of such curves are sandbags domed leather doming blocks of wood or metal, with hammers of wood or metal form.
Polishing: Polishing is a long process, where a piece is rubbed with increasingly fine paper wet dry to remove tool marks. Then, the wheel can be polished, polished with a fine polishing MOP on a mock hanging, or a polished barrel, where it dips in a soap solution with steel shot and rotate for 10 minutes or less. Polishing makes the piece smooth and shiny, free from all brands.
These were the basic techniques of silver vessels. Platero, however, take many other advanced techniques, as well as the manufacture of hand, casting lost wax, etc., die struck, and electroforming For starters, his best work initially on a base metal such as bronze or copper, since they are much cheaper metals to allow errors.
