How to carve jadeite in ancient times and how to process jadeite in ancient times.

1. Ancient jade carvings have special lines: natural jade is irregular. At first, people used ropes. This inspiration may come from the friction fire at that time, rubbing jade repeatedly with a rope, and breaking the jade after heating.

2. Tamping sand and grinding oars. The jade worker standing with a pestle in his hand tried to break the stone sand in the stone mortar. Another jade worker sat on a stool, in front of which stood a big sieve like a wok.

3. In "Sand Tamping and Pulping", a jade worker standing is holding a pestle and beating it with a pestle, so as to knock the stone sand in the stone mortar more finely.

4. In ancient times, jade products were carved with stone benches. When carving as shown in the figure, step on it with your feet, and then put jade sand on the knife edge with your hands. This carving process is very slow, and it often takes several years to complete a work.

5, rubbings, the original stone is wrapped in a differentiated leather bag, and it can only be known after cutting. Slice, cut stones, then slice and cut with a jade cutter. Draw a circle to ensure that the whole bracelet is free of any flaw lines. Round.

Ask experts to identify jadeite.

1, the cool feeling is the real jade. There is also a saying that real jade will be cooler in your hand. If you think about it carefully, it is not enough to use coolness as the basis for identification. Cool is our touch, which will change with the change of hand temperature. It is the real jade that can scratch the glass.

2. The identification of jadeite mainly depends on texture, hardness, emerald, relative density (specific gravity) and so on. Natural jadeite is transparent or translucent in texture, and its surface is bright and shiny. If you look closely, you can see the nearly round and slightly transparent "salt particles" and the fibrous substances around them.

3, weight, because the density of jade is relatively large, it feels heavy in the hand, so it may be real jade. On the contrary, it feels light in the hand and has no texture, which is fake jade.

4, look at the color root. Natural jadeite, especially green jadeite, has color roots. A color root is a place where green is thick, and then green will spread around the color root. Under the transmission of strong light, green will fade or disappear in some places, but the color root is still green.

5, look at the luster. Swing the jade left and right in the sun, carefully observe the luster of the jade surface, and identify the authenticity of the jade. Natural jadeite has a good glass luster, but the luster is not very strong. Jade has a strong resin luster after artificial dyeing and glue injection. Fluorescence reaction.

To learn jadeite, we must first know the truth and distinguish it, and don't be fooled by fakes in the market. Experts have a saying, called ...

1, look at the color root. Natural jadeite, especially green jadeite, has color roots. A color root is a place where green is thick, and then green will spread around the color root. Under the transmission of strong light, green will fade or disappear in some places, but the color root is still green.

2. Another method is soaking in water, which is mainly used to distinguish the true and false jadeite with bright colors. In order to get more vivid colors, fake jadeite usually deepens the color of jadeite by dyes, but when it is soaked in water, the dyed jadeite will fade and fade.

3. The phenomenon of "flying wing" is what we call jadeite, which is a sign of jadeite and an important basis for experts to identify with the naked eye. It is characterized by the appearance of irregular star-shaped and flaky flicker on the surface or inside of jadeite, which looks like "flying" wings.

4. Look at the surface of natural jade: the surface of natural jade will have "orange peel effect" or "flying wing phenomenon". This is all caused by the crystal structure of natural jadeite (as shown below), which is the key information on how to distinguish the authenticity of jadeite.

5. Under the transmitted light, observe the internal iron staining phenomenon with a magnifying glass. Dark jadeite is often dyed with iron (known as cat water in the industry), and there is yellow iron dyeing in the cracks, indicating that this product has not been bleached, otherwise it is impossible to have iron dyeing. But be aware that sometimes it will be yellow. Emerald usually looks cleaner after bleaching.
