But after the tsarist financial reforms of Peter the Great there was a coin, which was called chervonets. Its original purpose - payment for foreign products. The use of almost pure gold allowed to receive banknotes, which in value could be equaled to foreign coins.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-style-check is-layout-flow wp-block-quote-is-layout-flow\">\n<p>The word chervonny has Old Slavonic roots. It is still used in Ukrainian and means \"red. <\/p>\n<\/blockquote>\n\n\n\n<p>There are several versions of its origin:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>According to the first version, the word \"chervonny\" comes from the Czech language, in which \"CZERWONY\" means fiery.<\/strong><\/li>\n\n\n\n<li><strong>Another version indicates that the word appeared in the pre-revolutionary period, when Russia began to produce ten-ruble coins (chervontsy). Only high-grade metal in a duet with copper was used to make them. &nbsp;<\/strong><\/li>\n\n\n\n<li><strong>There is another version of how the word originated. The adjective (chervonny) came from the word (chervit and worm) which indicates a shade of red. The base of the words was the genus worms, which were used to make red paint.<\/strong><\/li>\n<\/ul>\n\n\n\n<p>Since the alloy was quite expensive and valuable, the chervonets were often melted down and used in the manufacture of jewelry for members of the nobility. At that time, such precious metal was considered the purest of all known. Today this adjective is used out of habit and ignorance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Composition and physical and chemical properties of chervonets<\/h2>\n\n\n\n<p>The antique metal originally possessed an increased ductility and brittleness, which made it easy to lose its shape, even with a minor impact or exposure.

The density of 999 is 19.3 g\/cm\u00b2. Other metals have a lower density, which means that when they are added to a ligature, the original characteristics of the precious metal change.  There is a way that you can determine the density at home without using chemicals. <br \/>\n<br \/>\nA test tube is needed, water is poured into it, and its level is recorded. A jewel is lowered into the container, and the test tube is weighed. The method has been known since ancient times and can help determine the density with an error of 20-30%.
