1, completely relying on manual excavation, the jade digger tied a rope around his waist, put an air hose on his mouth, put on an eye mask and a waterproof mirror, and sneaked into a river pond with stones falling from his waist. He found the original emerald by touching his feet, carried it ashore with a bamboo basket, distinguished the pros and cons and decided to abandon it.
2. Emerald can be mined in Myanmar. Speaking of the origin of jadeite original stone, it is of course Myanmar. Although there are many jadeite producing areas around the world, the quality is generally not high and the collection value is not high. Only North Myanmar can produce gem-grade jadeite. Mining jadeite raw stone in Myanmar is a job.
3. Seedling flushing, which is more suitable for areas with thin ground soil layer on the mine. After the soil on its surface is washed away by water, the jade digger will sort it with a pump. If larger stones are found, they will be sent out with shovels and crowbars. Then identify it.
4. The original jadeite stone is obtained by geological mining, and it is generally carried out by advanced mechanized mining. Therefore, the mining scene of jadeite raw stone is very spectacular, and the quantity is relatively large, and jadeites of various qualities are available. There are four main mining methods of jadeite, namely, digging holes, opening ponds, flushing seedlings and salvaging.
If you find a big stone exposed, use tools to dig it out for identification. "Salvage" is purely manual excavation. The jade digger tied a rope around his waist, connected an air hose, put on an eye mask and a waterproof mirror, identified the gravel and jadeite by touching his feet, found the original jadeite stone, and brought it up to identify the quality of jadeite.
How do Burmese get jadeite raw materials?
1, and the fourth method is "salvage method". This mining method is quite similar to the mining method of ancient Shentan inkstone miners. Workers dive into the water to identify gravel and jadeite, and then salvage them to the ground to identify the pros and cons and decide whether to accept them. This method is still used in fields along the Irrawaddy River.
2. Of course, it is to dig a hole or dig a hole in the place where there is jadeite ore, and the mined jadeite raw stone can be directly traded.
In 2003, several major mineral deposits were discovered in the Lu Wu basin of Myanmar (also known as Gu Wu, Wulong and Lu Wu), among which four are the most famous, namely Dumao, Myanmar, Panmao and Nannaimao.
4. Parabolic line saw marks that we often see on the jade surface are cut by this cutting method.
5. Three cutting methods of jadeite rough stone The wire cutting method uses ponytail and horsehair rope as saw blades, and sand and water are continuously added to them, and the "saw blade" is pulled back and forth to cut the gambling stone, and the material is slowly cut into two complete pieces. This cutting method is time-consuming and labor-intensive, and it also needs a lot of manpower to ensure it.
6. Use a small cutting machine to cut the types of jadeite raw materials such as pendants, jade brands and toys. Tuoqie method Tuoqie method is a cutting method of jadeite original stone used in our ancestors' time.
