Thrush rose in the Warring States period. In the absence of thrush materials at that time, women burned willow branches and painted them on their eyebrows to form a dark gray effect. Later, the earliest thrush material was Dai, a black mineral, also called Dai? Shi Dai? Usage is a bit like pearl powder, grinding and mixing. Before painting, Shi Dai must be ground into powder on the inkstone and then mixed with water. Besides stone, there are bronze, bluebird and snail. Stone generation is a black mineral, and copper generation is a chemical substance similar to copper rust. Jade bird headgear is a kind of dark gray thrush material, and snail headgear is a thrush material used by women in Sui and Tang Dynasties, which was produced in Persia. It is a kind of Dai product with various specified shapes. Later, in the Song Dynasty, thrush ink was more widely used, and women rarely used Shi Dai again. Another way is to make your own thrush ink.

There are also narratives in the notes of Song people. For example, "The Stone Forest" wrote: A really fragrant oil lamp, with many lamp holders, is rubbed tightly. Put the oil lamp in the water, light it, cover it with a small device, let the smoke condense, and sweep it down when necessary. Soak musk deer in less oil three days in advance, pour it into smoke and mix well. The ink can exceed the paint. One-way rotary shearing of sesame oil snuff is particularly preferred. ?

The screw can be a luxury in ancient thrush tools. On the one hand, it is easy to use, and it does not need to be ground directly in water. On the other hand, it is too expensive. Snail Dai first appeared in the most expensive emperor period of Sui Dynasty. Emperor Yang Di forced him to be 15 or 16 when he toured the south of the Yangtze River? Temple foot girl? Pulling color cables for him, Wu Jiangxian is one of them.

Emperor Yang Di was attracted by her long moth eyebrows, so he took Wu Jiang Xian into the palace, named her Mrs. Kongtong, loved her very much, and gave her everything she brought from Persia? Descendants? After thrush, the treasury ran out of money, so Yang Di gave the money to other concubines? Tong Dai? , but the price for Wu Jiangxian is still ten gold each? Descendants? .

How much is a snail? Ten gold, about two hundred and forty taels, and one tael of silver in the middle and late Qing Dynasty was worth about RMB 150-220 yuan. If calculated according to RMB 150, a snail is 36 thousand. There may be some deviation in conversion, but it seems that the value of snail wear is definitely a luxury at present.
