Chinese sword Source and legend
Source and legend
It is said that the man who invented the weapon in China is the shennongshi, the exact date cannot be verified. Shennong successively with stone and YuCai weapons, as a result of jade brittle material is not suitable for actual combat, can only be used for ceremonial, and then a bronze weapons, shape has a sword, and spear, myth was invented by human-god. Human-god, destroy the governors to expand the territory, and finally with the army of the yellow emperor in integration involved problems.the zhuolu (now hebei) within the territory of fierce fighting, although ultimately defeat human-god, was executed, the yellow emperor but courageous warrior and invention metal weapons human-god, be remembered as "god's army" worship, spread through the ages.
Production and manufacturing
Every dynasty in China has a large army, usually hundreds of thousands of people. Emperor yangdi expedition in Korea, there are more than 100 soldiers, to such a large armed forces, must have a massive weapons production system support, so not only has the country directly under the authority of manufacture weapons, weapons of folk and local fang also emerge in endlessly. Craftsmen must undergo rigorous professional training. In the tang dynasty, the training time for knife-makers was 2 years. From the han dynasty to the Ming dynasty, China not only surpassed the countries in the number of sword manufacturing, but also led the way in steel smelting technology. Smelting technology of mature is: (1) the development of more than 1200 ℃ high temperature furnace, thus, the refined under high temperature. (2) invented the blast furnace, which can continuously provide sufficient air in the process of smelting and always maintain the high temperature in the furnace to achieve the effect of refining. (3) successful use of coal as raw material for ironmaking can quickly obtain high temperature effects. If the melt in the temperature of 800 ~ 900 ℃, iron carbon is low, the iron is too soft. The iron can be removed by coal heating to remove impurities, increase the carbon content and increase the hardness of iron. This kind of steelmaking technology had already begun in the warring states period and reached maturity in the han dynasty. (4) from the practice, it has been found that folding and forging can increase the toughness of steel and harden the processing method of hardness. Therefore, the theory of "100 steel" or "one hundred knives" is used. It is widely used in the Chinese to improve the quenching technology of the heated iron to improve hardness, and it is generally used to improve the hardness of the tool, especially the cutting edge. In the process of quenching, the control of water temperature and the selection of water quality are particular. By the sixth century, some of the animals had been used in the urine or grease of wild animals as hardened materials. The iron is hardened after hardening, but it is also brittle. In the northern song dynasty, the cold forging method was adopted to process the cutting tools.
The so-called pattern steel refers to the texture of the tool in order to increase the strength and toughness of the tool. The original meaning of the grain is practical, and then developed into an art. The artistic representation of the grain is of course the value of the work. The term "pattern steel" is a modern idiom, also known as Damascus steel, which is known in Japan as the "ground muscle". It is known that the forging pattern in China can reflect its scientific implication and process method.
The modern pattern steel seems to have mysterious and worship psychology, blade grain is actually in the process of smithing traces left by the process, the additional value of art, should not be regarded as how artifact. In addition to our country, Asian ancient weapons are mostly made of so-called "decorative steel", with islamic countries as well as India, southeast Asia and other areas of the most beautiful lines. In terms of Chinese ancient sword, as long as in the traditional craft of mostly pattern steel, but due to the material and smithing way different from other Asian countries, so the grain is not easy to appear, but it's not lines.
Modern people due to excessive pursuit of grain, then using a percentage of the smudge tool surface acidic liquid make pattern, but with excessive acid can make hair black knife surface and lost its shine, and quality is damaged, so should pay attention to in the process of pursuing the pattern steel forging quality and texture of art effect, rather than have a grain is nod, because with almost all lines of ancient dao, and even modern follow made in ancient works, the fancy and magnificence of the grain as much as ancient dao. Understanding this point can understand that the work itself is only ancient and modern, good, material and material, but not true or false. The art effect of the forging pattern has a lot to do with the abrasive materials and technology. In Japan, a kind of abrasive stone called "the earth yan" is used to deal with the quenching, which shows the fine forging pattern. Steel "grinds", made of steel, are treated like diamonds of steel. Using straw ash, deerhorn powder, bovine saliva and other special materials to deal with the crystallization phenomenon, it presents the pattern of the star like water cloud. If China can make a breakthrough in the tool grinding materials and technology, the luster and sharpness of baodao will be reproduced.
