Due to the natural physical and chemical characteristics, gold has found application in many areas: jewelry industry, chemical industry, medicine<\/a>, dentistry, etc. Clean precious metal<\/a> is soft, malleable, which makes it lose its jewelry value. Manufacturers use an alloy of different metals, which increase the strength, durability, improving the consumer properties of products. <\/p>\n\n\n\n

The ligature composition is very diverse, defines a wide range of gold products.<\/p><\/blockquote>\n\n\n\n

Ligature and ligature gold - what are they, auxiliary alloys, what applies<\/h2>\n\n\n\n

Most of the mined metals initially contain unnecessary components. After extracting the reserves from the earth's crust, the raw materials are processed for further transportation. Dore alloy is made from mined ore that is saturated with various elements. This form allows the future noble metal to undergo refining at specialized plants, where it is purified of impurities.<\/p>\n\n\n\n

Pure precious metal itself is quite malleable, which makes it unsuitable for the manufacture of various objects. <\/p><\/blockquote>\n\n\n\n

However, ligature gold is highly prized by jewelers. The addition of other elements can change the physical properties of precious metals, improve their wear resistance and appearance.<\/p>\n\n\n\n

A ligature involves mixing together pure metals without any impurities. Several refined components can be added to the precious metal at the same time: copper, platinum, silver. The composition is characterized by strength, malleability, which is important in the manufacture of jewelry.<\/p>\n\n\n\n

Historical fact of the appearance of the ligature in the monetary system<\/h2>\n\n\n\n

As early as the Middle Ages the noble metal's physical characteristics led to the search for methods of increasing gold's hardness. Coins made of pure precious metal lost their weight over time and became deformed. That's when ligature for gold appeared in the monetary system, allowing to prevent coins from rubbing off thanks to addition of non-ferrous metals.<\/p>\n\n\n\n

Such a decision caused differences between the images on the coins and their real composition. This difference began to be noticed by \"money changers\" of the time, who checked the authenticity of coins by rubbing them against a rug. Pure gold money shrank and lost weight, while the mat accumulated a large quantity of noble metal. <\/p>\n\n\n\n

Gradually, the full-weight coins in circulation ran out, leaving only the incomplete ones. There was a depreciation of the old means of payment.<\/p><\/blockquote>\n\n\n\n

The metals that determine the color of gold<\/h2>\n\n\n\n

The color directly depends on the composition of the jewelry and the proportion of impurities:<\/p>\n\n\n\n
