Bashan jade may be a strange name for most people, but this is a very cheap one in jade. Everyone can be used as an entry section. Let us tell you how to distinguish between Bashan jade and jade.
Is Bashan jade jade?
Bashan jade has a close relationship with jade, but it is not a pure Burmese jade, but a special jade with a lower grade.
Bashan jade can be said to be jade, but it will not be sold directly. It is usually sold after BC treatment. Because, Basan jade has the characteristics of medium grain and coarse grain structure, which is beneficial to chemical treatment; and its transparency is poor, and it is necessary to increase its transparency through processing. Therefore, in the jade articles of the eight-jad jade seen on the market, More than 95% are processed B goods.
What are the characteristics of Bashan jade?
Natural Bashan jade
1) "Bao Sanyu" is reddish at the end, often with violet (spring color), or with a light green, light gray.
2) The inside has black, blue-gray plaques, and its green color is patchy, blocky, and strip-shaped, but not clear enough.
3) "Basanyu" has a good head and a strong sense of crystal, but the structure is not dense, and there are many jade patterns (natural invisible cracks).
4) "Eight three jade" grain is thick, the structure is loose, and the sound is boring.
Processed Bashan jade:
1. Bashan jade cannot be directly used as raw material for jade products due to structural reasons, and its finished products must be optimized. The structure, color, transparency, hardness and gloss of the treated Bashan jade have changed.
2. The structural change in the area of ​​the jade's edge, surface or fissure is most obvious, and the degree of damage is deep. The jade center or the area where the original is dense and the crack is small is less damaged, which makes the treated Bashan jade have uneven characteristics.
3. The color of the treated Bashan jade is still the original color, but it is soaked by the acidic solution, the base becomes white, and the green is yellow. Light spinach green like jade, but it looks unnatural. The shape is transformed from natural flakes, strips to spots, wickers and pieces, messy and floating.
4. The transparency has been greatly improved after the improvement. Bashan jade stone is mostly opaque-translucent, but because of the large number of cracks and wide distribution, the degree of treatment is deep, and the treated jade has changed greatly, reaching translucent-transparent, and the overall moisturization is close to high-quality jade. But the level of detail is still poor. After the improvement, the hardness drops a lot. The hardness of Bashan jade raw material is slightly lower than that of jadeite, and the hardness of the finished product is reduced to an average of 6.6 due to the congenital texture loosening and later acid rinsing, and there is no shortage of them.
5, the gloss is greatly improved after the improvement, up to the glass luster, but the brightness is not as good as jade, there is a tendency of B goods, with the feeling of resin or grease.
The difference between Bashan jade and jade
1. Jadeite is a fibrous aggregate composed of pyroxene-based pyroxene minerals, that is to say 80% are jadeite, which is produced under the condition of insufficient silica and certain temperature and ultra-high pressure. Bashan jade is on the edge of the jadeite ore body. It must be formed with a large amount of silica. Therefore, although it is mainly jadeite, it contains more amphibole and albite.
2. In terms of density, hardness and toughness, the jadeite is higher than the Bashan jade.
Bashan jade and jade B goods difference
Similarity: Due to the low specific gravity of Bashan jade, the structure is not dense, the natural hidden crack, the knocking sound is boring, it is easy to identify it as B goods.
difference:
1. Jade B goods are treated with strong acid by artificial methods, the structure has been destroyed, and the shallow structure becomes loose and exclusive, and the emerald nature is not obvious;
2, Bashan jade structure is a patchy crystal structure, although the particle size difference is large, but the structure is complete, not loose;
3, Jade B goods gloss is waxy, feeling dull; Bashan jade is glass shiny, bright.
4, B goods are more green, floating, unreal, no roots; Bashan jade floating gray orchid, color is real, has roots.
5, from the infrared spectrum, Jade B goods have a colloidal peak, Bashan jade does not.
Bashan jade maintenance rule
First, check the structure of Peiyu regularly
In order to prevent it from being lost or broken, it is necessary to periodically check that the inlay is firm. Once structural problems are discovered, they are reinforced in time.
Second, regular cleaning Peiyu
Peiyu is easily contaminated when it is worn. For example, the secretions of the human body, the dust in the air, etc., should be cleaned up in time; otherwise it will be difficult to return. If it causes permanent damage to jade, it will not be worth the loss.
Third, don't let Peiyu suffer a sharp collision
Due to the fragile physical properties of jade, especially when subjected to large external forces, it is cracked lightly, and the weight is directly broken in the direction of cleavage. Therefore, in the occasion of engaging in intense sports or other situations that may damage Peiyu, Peiyu will be removed.
This type of T-shirt also has breathable functions, but compared to tight-fitting T-shirts, this type of T-shirt will be looser, and wearing it will feel refreshing because it also uses skin-friendly and breathable fabrics, reducing the situation of sweat sticking to the clothes on the back to a certain extent. According to customer feedback, wearing this type of T-shirt in summer will give a cool feeling and will not feel stuffy.
