How to judge the new and old workers in the jade carving process?

Look at the amount of material he has consumed, the effect that has been carved, and the complexity of the process that has been carved.

In the general jade carving process, the new workers are carved with relatively cheap jade and relatively simple process lines, because the carving of jade is very modified, and the carving is destroyed if it is broken, and it is difficult to save, so the jade carved for the new workers is generally cheaper and simpler.

And the old workers are different, the old workers of jade carving, there are a lot of craftsmanship, will carve a variety of patterns, and can be designed according to the shape of the jade rough stone to carve into what kind of most valuable, the highest value, moreover, a lot of jade will have "white spots" or "black spots" or "black lines" and other flaws, the old workers can design a suitable pattern, just to be able to remove these flaws or transform them into characteristics to stay, improve the value of jade.

Or it is the ability to design a shape so that the color on the jade becomes the characteristic feature of the finished product, rather than its flaws.

This is the difference between old workers and new workers, in general, old workers are more able to give full play to the value of jade.

Wood carving, bamboo carving, brocade, root carving and other industries, after thousands of years of inheritance, no matter how the tools are improved, the process of using power tools will not be called manual! The jade carving industry has no craftsman spirit, and the craftsmanship of power tools is called handmade jade carving to deceive consumers! Treat the craftsmanship of power tools as a traditional craft to apply for "Intangible Cultural Heritage"!

Is there an electric one for traditional crafts?

If you do it, you can call it manual, then the workers in the workshop assembly line who use electric car beds to produce products also do it, can it be called manual production? Hitting the keyboard to print the file also started, is it called manual printing?

It is treasured in the Anyang Yinji Art Museum.

The material is selected, the shape is meaningful, the work is respected, the god has sought, and the ancient jade that conforms to these five sentences is a good collection, and it is the creation of our ancestors' magic workmanship, which is a watershed to distinguish the old jade and the new work.

The distinction between "new workers" and old workers in jade handicrafts.

The difference between old and new workers stems from the different tools and abrasives used, as well as the various phenomena and traces produced by the speed, efficiency and accuracy of these tools.

The process of the old worker (referring to the iron thallium worker) is roughly as follows: pounding stones, grinding (or collecting natural sand), opening jade, digging out the jade, flowering, cutting jade, grinding jade, punching, and glazing. Their common characteristics are that they use manpower and iron thallium, the rotation speed is not fast, and the jade is sharpened by jade sand, and the materials and equipment are worn at the same time.

The old workers use manual positioning and control, the accuracy is poor, the geometric error is large, and there will be discrepancies in parallelism, datum, graphic symmetry, etc. However, the old medium is fine, the grinding amount is small, the processing strength is light, the cycle is long, and the jade parts do not heat up. The jade pieces carefully made by the old workers are very exquisite, the shape is symmetrical, the lines are smooth, the bores are wide, the ground is soft and flat, and the polishing is bright.

The process of the new worker is: jade with grinding wheel, after the rough grinding tool is removed, a flexible shaft is driven by a stepless variable speed motor, and the flexible shaft chuck can be replaced with a different grinding wheel head made of artificial emery, and the maximum speed can reach 10,000 revolutions per minute. Due to the high speed of emery stone and fast grinding, the production time is greatly reduced, and the work efficiency is significantly improved.

It is precisely because of this that the rough work of the new workers often has traces of rapid success, such as: the dry grinding phenomenon occurs at high speed, the jade table will heat up, due to the large amount of grinding when drilling and opening the window, the grinding wheel particle size is coarse, the grinding is fast, and the phenomenon of pulling hair after heating will be seen on the side wall of the drilling hole or window, and the jade table presents some grooves around the drilling hole or window, parallel burrs, and sometimes the color of yellow burn will be seen.

That is, new, modern engraving equipment.
