Sterling silver is a silver alloy which contains a 92.5 percent of silver weight and a 7.5 percent of other metals weight, most commonly is copper. That standard often has minimum 925 millesimal fineness. There are other metals which may replace a copper which are being utilized in order to improve the various properties of a sterling silver handmade jewelry like eliminating the fire scale, increasing the resistance to the tarnish, and reducing the casting porosity.
All the natural components will be under going the several kinds of processes. And also, because these are unique, it need to be produced given with ample time and having all the necessary skills. These following paragraphs are some descriptions and brief discussions about some processes involved in the manufacturing chain.
First is to buy the stones and silver. To buy the right set is considered very important. It is one expensive type of investment, so it must be considered properly before purchasing. Types of these are bought in different sizes and weight, so to know about these is very important as well before purchasing. Also, make sure that you are gaining the availability of best materials.
Second, designing the jewelry. All things are being made and started with concepts and these are considered as the rough design when it comes to the minds of designers. These concepts and drawings are being uses by model makers as reference for the creation of an original piece. Creating the design can be very passionate alchemy but can be difficult as well.
Third is the molding of products. If master pieces are already done, these will now be used for creating high technology mold which will also be used for creating the jewelry in wax reproduction. If all final details are already sketched, these are passed to the section of molding. Professional molders in this section will be turning products from sketches to molds.
Fourth is the casting of product. Metallic pieces are often unique. For example, an engagement ring which is customized is going to be used in rubber molds and it may be made through the low wax casting. Its shape will be shaped initially by the use of wax or metal that has the scale of 1.05 to reduce slightly the metal piece dimensions.
Fifth is to set up stones. This process involves two attachment techniques for the gems and stones. First, using the claw setting or prong setting. The purpose of prongs is to secure the stones through folding it over the girdles. Second, using bezel setting. To secure the stones, bezels will surround stones and are folded over the perimeters.
Sixth, polishing and checking the quality. Two types of polishing are mechanical and chemical polishing. In the mechanical type, a felt or a cotton disc which is dipped in an abrasive compound is used for polishing the surface. While the chemical type is not often utilized for alloys since it is risky for jewelry making. After, all the pieces are checked for any defects by the experienced workers for quality checking.
