In nature gold is found more often in native form and has little in common with the famous element aurum of the periodic table. This mineral is a natural stable solution of silver in gold doped with other metals. To get the pure gold, it should be cleared.
At the beginning the rock is granulated and enriched, and then put in the solution of sodium cyanide or potassium. From this solution the gold is segregated by electrolysis – this process is called refining. Unfortunately, gold pure, cleared from impurities is not used in the jewelry business.
It is too soft to make a thing of it that can be taken with you daily. If you droplet down a product of pure gold, an impressive dint will remain. That is why, in pure gold back it is added metals – silver, copper, palladium, platinum, which have the name ligature. The result is the so-called “color gold.”
How, what and how much must be added to pure gold to get the needed color was determined empirically by the jewelers-experimenters, then the results of their researches were fixed in the legal system and called this proportion the “sample”.
The sample shows how many shares of gold and ligature are fallen on 1000 units of mass – such a system is assumed in a lot of countries. In the West it is used 24-karat system of samples. To obtain the most accustomed to us – yellow gold- they add equal amount of silver and copper. In order to obtain the red, “pure” gold, they add plenty of copper.
The most fashionable is white gold these days. It is obtained when in pure gold it is added 15% of palladium and 10% of a compound of copper and nickel. Owners of watches of white gold like say others: “I am nifty and rich, but smart enough not to make a parade of it.”
It is easy to take white gold for steel or platinum. For the not versed observer, all these metals are resembling, but someone who knows a thing in the jewelry art will understand at once what it is. The body made of white gold usually becomes a dignified framework of masterpieces of watchmaking – compound mechanical watches. Today jewelers are increasingly experimentalizing with the color: they have already obtained pink gold (9% silver and 16% copper) and an exotic green gold (25% silver).
Affinage and appending ligatures are rather time-consuming processes, they are made only in public companies, having a license. That is why, the vast majority of manufactures of gold watches buy at them ready-made alloys or billets of watch-cases and parts of bracelets on their own sketches. These billets can be of two types – repousse and cast.
I must say that stamping can be of two types – the volume, when the metal is poured into the stamps, and the sheet, when the parts are cut from a plate of needed thickness. Stamping is applied only for small parts – dials and hands. Stamping – is a very convenient method, the metal is spent very sparingly. But using it you cannot make pieces of complex shapes – with a lot of angles or with complex convexities.
