1, different concepts.

Silver, namely silver, is called silver because of its white color, as opposed to gold. Think of it as money and decorations. In ancient times, money was called silver. Pure silver has a specific gravity of 10.5, a melting point of 960.5℃, good conductivity, and is soluble in nitric acid and sulfuric acid. Silver is one of the metals found in ancient times.

Tattoo is also called "footprint". An old standard silver in China. Striped silver is not actual silver, but a unit of accounting currency used to exchange various colors of metallic silver, that is, virtual silver, including Guanping, Kuping, Shi Ping and Caoping.

2. Different colors

Silver is white, metallic luster mixed with impurities, soft, hardened after mixed with impurities, and the color is grayish red.

The reason why tattooed silver is used as a monetary unit is that the actual silver in ancient China has different colors and many names, such as Si Yuan, Qingsi, Baisi, Shuisi, Xiqiao, Shishou, Liuqiu, Camellia and Fennel.

3. Different in nature

Silver has rich ductility and is a metal with good thermal and electrical conductivity. The first ionization energy is 7.576 eV. The chemical properties are stable and have no influence on water and oxygen in the atmosphere; Soluble in dilute nitric acid, hot concentrated sulfuric acid, hydrochloric acid and molten sodium hydroxide.

Serpentine, also known as "925 silver", is usually composed of 92.5% silver and 7.5% copper. Because of the addition of copper, the polished product is brighter and more beautiful than silver, and because of the addition of copper, it will turn red after a long time.

Extended data:

The main uses of silver are mainly based on three pillars: industry, photography and jewelry and silverware. The total demand of these three types of silver accounts for about 85% of the demand for silver.

Since ancient times, silver and gold have been regarded as a symbol of wealth together. The chemical symbol of silver is Ag, which comes from the Latin Argertum, meaning "light and brightness". Because silver is white, it is called "silver".

Silver not only has good electrothermal conductivity, but also has high photosensitivity and luminous characteristics, and is used in industry, photography, jewelry, currency manufacturing and so on.

Compared with gold, silver was used for coinage more and earlier and entered the circulation field because of its large supply and low value. Many countries have established the silver standard, with silver coins as the mainstream currency.

The metallic silver in the actual circulation field is called "Yin Bao" by ingot makers, that is, silver ingots in the form of ingots. Due to the different colors of precious metal silver in different places, there are place names or water application standards in front of them, such as Su, Wuchang, Zubao, Ersibao, Erwubao and Erliubao. "Ersibao" means that every fifty-two "Ersibao" silver ingots are converted into fifty-two standard grains of silver. The fineness of precious silver is usually higher than that of textured silver. Zheng's "Dangerous Words in Prosperity". Casting silver said: "The big one with silver stripes is an ingot, and the small one is an ingot. Or 120, or 520, or even 232. "

After the Opium War, silver coins and silver dollars were circulated in China at the same time, but the official statistics of tax revenue, budget formulation and foreign reparations were still measured in kuping coins and official ping coins. 1933, the Kuomintang government announced the abolition of the two yuan, stipulating that all revenues and expenditures should no longer use silver, but should all use silver dollars. Serpentine is out of circulation.
