Handed down jade: Generally speaking, jade that has been passed down for more than three generations can be called handed down jade.

Unearthed jade: jade unearthed underground, including jade unearthed from ancient tombs, ancient sites and territorial waters, can be called unearthed jade.

Make old: it is usually used on antique jade articles, with the purpose of making the jade surface look old, making its surface more similar and closer to the era of imitation. There are many ways to make old things, such as chemical etching, burning, boiling and heating, deep underground soil leaching and so on.

Soil bites loess: make mud with pig blood and loess, and then bury jade in it. After a long time, there are traces of mud biting loess, rust and blood on the jade.

Making loess rust: coat jade with glue and then bury it in loess mud. The longer it is buried, the more similar the loess rusts.

Hematopoietic infiltration: red spots on the surface of jade, which are called spots in terms, commonly known as hematopoiesis or corpse infiltration. Hematopoietic ooze is a common method of forging old jade by various methods. Mainly: First, after the jade is successfully copied according to the old style, it is burned red on the fire, put into the belly of a live cat or dog while it is hot, buried underground, and dug up a year later. Second, after the jade is successfully copied according to the old style, it is heated in the fire, and the dragon's blood is applied while it is hot, and it is repeated many times until the blood seeps in. Thirdly, put Sanguis Draxonis, Radix Arnebiae, and Caulis et Folium Gaultheriae Yunnanensis into a jar filled with jade, pour it into a pot, and boil it for several days, so that the color permeates into the jade; Then use the wrong grass to wipe off the floating light on the jade surface, then put the white wax on Sichuan and play with it in your hand every day, and you will be like an old jade. Fourthly, prepare one or two pieces of dragon's blood and one or two pieces of broken stones, add dental sand and grind them into fine powder, put them into a jar and fill them with fat oil; In addition, put the jade in dried apricot water and cook it for several hours, then put it in an oil pot while it is hot and cook it with low fire for dozens of days. When the color of jade soaks in, take out the wrong grass and Sichuan ash in turn.

Sheep jade: refers to jade that uses living animals to make blood ooze. Sew the new jade imitating the old style into a strong live leg of lamb, and take it out one or two years later, hence the name.

Dog jade: kill the dog, cut open the abdomen, put the jade into the dog's abdomen while the dog's blood is still hot and not solidified, sew it up, bury it underground in the road, and take it out a few years later. There is blood on the jade. But compared with the real ancient jade, it has the color of new jade and the traces of carving.

Lu Zigang, a native of Taicang (now Taicang County, Jiangsu Province), was the most famous Suzhou jade carving master in the Ming Dynasty. Lu Zigang's jade-making skills are unique. According to the document "Taicang County Records", "Jade articles are all sand. Fifty years ago, someone in the state, such as Lu Zigang, carved with a knife and was good at it. Today's Hosta is worth 56 gold each. The child has just died, and the skills are not passed down. " The jades made by it are of good quality and high value, so they were copied in large quantities with their descendants at that time and passed down many times. It's just that the inscription is: "Zigang", "Zigang" and "Subnet" are mixed together, so it's difficult to tell who is true and who is false. Lu Zigang's representative works are: white jade printing pool, jade hairpin, combined cup and so on.

Rust spot (knocking rust): Jade is mixed with iron filings, then quenched with hot wax, buried in the ground ten days later and taken out several months later. After the jade is buried, the surface will be corroded by rust, and orange peel lines will appear, mixed with soil spots and crimson rust, commonly known as "knocking rust".

Archaeologists in China believe that there was a jade age between the Neolithic Age and the Bronze and Iron Age. The earliest basic difference between eastern and western cultures was whether there was a developed jade culture in the Neolithic Age. The wisdom of oriental civilization shines brilliantly on jade, which is one of the most attractive traditional handicrafts in China and is worth cherishing.

Jade is universally respected and cherished by China people. From the beginning of civilization to today, no matter how great the Chinese culture has experienced, the national feelings of worshipping and loving jade are still deeply rooted, and the art of jade carving is endless. Archaeological data show that seven or eight thousand years ago, our ancestors knew about beautiful and solid nephrite, which was ground into military symbols and carved into ornaments. Some beautiful stones, such as jade, were also adopted by our ancestors.
