Most people are familiar with gold white<\/a> \u0438 yellow<\/a>But this is by no means a complete list of varieties of the precious metal. Among them, there are rarer ones, such as the blue alloy colors<\/a>. Jewelry made of such material is in demand despite the fact that their price<\/a> tens and sometimes hundreds of times higher than the average market value of this category of products. This is explained by the difficulties associated with manufacturing alloy<\/a>. <\/p>\n\n\n\n

\n

It is still unknown exactly how the blue gold was previously obtained. <\/p>\n<\/blockquote>\n\n\n\n

Several methods have been unraveled and are used today. However, in order to preserve the original properties, it is necessary to ensure proper care of the products.<\/p>\n\n\n\n

What is blue gold<\/h2>\n\n\n\n

Blue, blue gold are similar metals, but they differ in the intensity of the hue, which is due to the difference between the compositions. Alloys can be obtained by various methods, but not all of the finished materials are characterized by suitable performance parameters. In addition, even the blue color sometimes does not correspond to the color coordinates of CIELAB, the metal so conventionally. In fact, the precious metal obtained using one of the techniques is characterized by a grayish hue. When the composition is changed, it takes on a bluish tone. These materials belong to the group of intermetallides. <\/p>\n\n\n\n

\n

These are alloys obtained by chemical reactions in the interaction of different components.<\/p>\n<\/blockquote>\n\n\n\n

The History of the Discovery of Scythian Gold. Recipes of the ancient alchemists. Antoniassi's Secret Technology<\/h2>\n\n\n\n

Blue gold is a mystery that has not yet been solved. The alloy has been in use for a long time; the first products are several thousand years old. It is believed that the Scythians were the first to produce blue gold. <\/p>\n\n\n\n

Some items have survived to the present day, but they are of high value and therefore cannot be taken for analyses to determine the component composition and to clarify the technology of production of the precious metal. At the same time, evidence has been found that a method based on combining the gold<\/a> and iron in a ratio of 3:1.<\/p>\n\n\n\n

\n

Even later (in the 17th century), the Argentine goldsmith Antoniassi developed a technology that made it possible to obtain a true heavenly color and a high purity (985) precious metal.<\/p>\n<\/blockquote>\n\n\n\n

He kept the secret of creating the material secret, but international rules require that a list of components be provided, so the composition was revealed. It turned out that this was not enough to recreate the precious metal with a heavenly hue; it was necessary to know the technology of the process. Some jewelers figured it out on their own.<\/p>\n\n\n\n

Composition, shades and grades of blue and blue gold<\/h2>\n\n\n\n

Today you can buy jewelry made of a rare alloy, which includes components: gold itself, steel, platinum, iridium. Their ratio, respectively: 75%, 22%, 2.5% and 0.5%. This version of the celestial-colored precious metal is the most common today. In comparison, the Argentinian Antoniassi previously used a method based on 90% gold, to which a small amount of cadmium was added, among other things. Nowadays, other intermetallides (alloys chemically obtained on the basis of 2 or more metals) are also used:<\/p>\n\n\n\n
