Water stool

The water stool is a simple device for making jade articles invented by the ancients. It is the first procedure for processing jade articles in a workshop. Use a round steel knife to mount the wheel, pull it with a rope, and rotate it with pedals to open the jade. Because jade must be filled with sand and water, it is called a water stool.

The structure of the water stool is a rectangular wooden shelf with a horizontally and vertically installed horizontal pole. There is a water sink under the horizontal pole, a wooden pole can be inserted next to it, and a bucket is hung on it for cooling during grinding. There is a round hole at the front end of the horizontal pole, and the raccoon can be glued to it with thermoplastic shellac. The rear part of the horizontal bar has a thickness change, and a leather strip is wound there for two or three weeks, and the leather strip is connected to the pedal at both ends. When working, people use their legs to move the pedals. Pulling the leather strip to rotate will cause the horizontal rod to rotate, and at the same time, the mule will also rotate. The jade worker held the jade material with both hands and grinded it at the lower end of the mule. The position of the moving pimp at the rear of the horizontal rod can be changed by using the thickness of the rear of the horizontal rod to change the speed ratio, but the range of adjustment of the rotational speed is limited.

The characteristic of the water stool is that the rotation speed is not fast, and the adjustment range of the rotation speed is extremely limited. The rotation mode is rotated back and forth. The grinding of the jade on the jade also swings back and forth, thus forming the technical characteristics. Modern electric jade carving machine rotates clockwise at high speed (5000 6000 rpm), and uses diamond powder jigs. The work efficiency is improved a lot, but the score is different. Experienced people can see whether the jade is made of a water stool or an electric jade cutter according to the difference in the score, so that they can identify whether it is new imitation jade or ancient jade.

There are five types of water stools

Rush. Okinawa specializes in the treatment of unshaped raw jade, which is used to form objects. For example, there is a piece of white jade, which is planned to be a wine glass, that is, a cup shape is opened by punching. The edges and corners of the outside of the glass still exist, just like a glass. The punching is made of thick iron plates in a circle, which is a little thick. The middle is made of wooden crosses. The center of the frame is equipped with a wooden shaft. The diameter of the punches varies from one foot to the other.

Grind. The rough edges and corners of the utensil are ground into flat light. The shape is the same as that of the scoop, only a little thin. There is no cross inside the iron plate, and the scoop is set with a whole round wooden board. The scaffold is also wooden.

. Open the whole jade, or remove the large corners of the object. So is sometimes used before rushing, sometimes after rushing. A round knife made of steel with a sharp edge and a wooden shaft.

rolling. It is used for embossing the pattern after the utensil is shaped, and then lifting and removing the pattern to make it beautiful. The rolling mill is smaller than the grinding mill. There is a long nail in the center of the mill. A hollow iron shaft is used, and the shaft is filled with shellac. Insert the long nails of the cymbal into the shaft, which is much firmer than the punches, mills, and cymbals.

Hooked. After the utensil is formed, first draw the pattern with ink pen. In order to be wiped off by water, you must apply a layer of white wax, and then use the hook to engrav the outline before rolling up the ground. This is the first step to spend on jadeware. The hooks are made by workers themselves using small pieces of iron, but they use wooden shafts and hooks with iron shafts. The hooks vary in size. Replace the hoe depending on the shape. If it is an exquisite small object, the hoe can be as small as a nail tip, the largest is only three or four inches. The most difficult thing about jade craftsmanship is the ready-made tools. It s hard to know that three-fifths of the art and fashion tools and two-fifths do the work. The water stool tool is the easiest one.
