Frozen ground bloodstone, do you understand?
The bloodstone is the ground stone of the cinnabar strip. It is named after the bright red cinnabar (cinnabar). The bloodstone contains cinnabar (cinnabar), quartz, and chalcedony 35%-45%. Magnetite and hematite are 6%-12%. Cinnabar is about 5%-8%.
The bloodstone is juxtaposed with Shoushan Stone, Qingtian Stone and Balin Stone, and enjoys the reputation of China's "Four National Stones". Mainly used as a seal or craft engraving material. China discovered the bloodstone of Yuyan Mountain in Changhua, Zhejiang. Later, he discovered the Bahrain Bloodstone in Bahrain Right Banner, Chifeng City, Inner Mongolia. In the 1990s, bloodstones were found in Guizhou, Shaanxi, Gansu, Sichuan, Hunan, and Yunnan.
Due to the limited production of bloodstone, the market price is enduring.
The frozen bloodstone is a species of the bloodstone.
Frozen ground bloodstone: the main component is a natural aggregate composed of cinnabar and dickite, kaolinite, including glass jelly, sheep fat, horn jelly, peach jelly, etc., transparent or translucent, usually hardness 2, 3 about.
Monochrome frozen common: white, black, yellow, etc., the name is "glass ball", "shallow fat", "crown frozen", "peach blossom frozen", etc.; mixed color is multi-color associated.
The frozen bloodstone is the elite of the bloodstone, which has always been the main goal pursued by people and the main target of mining. Many famous products and treasures are from this variety.
Due to the high price of bloodstone, there are many fakes. Therefore, we must understand its identification method.
1. Identification of counterfeit goods
Due to its characteristic "chicken blood", the bloodstone is generally not easily confused with other jade, but there are still a few similarities between the appearance of jade and the bloodstone. These kinds of jade are fake blood bloodstone, cinnabar jade, blood chalcedony, Shoushan stone and dyed jade.
False blood bloodstone: fake blood bloodstone is mainly artificially infiltrated by natural Changhua and Bahrain stone with poor texture or blood, and dyed into bright red. The organic dye or ink is filled in the crack and, after drying, is coated with a protective resin. Most of the fake blood is unnatural, the blood color is single, and the appearance is shining under the sunlight or the light. This is because the fake blood contains gelatin. The blood shape, size and shape of the fake blood are relatively consistent, and the blood shape of the real blood is natural and smooth. .
2, split stone identification
There are two kinds of splicing bloodstone and inlaid bloodstone. When identifying, as long as it is serious, it is not difficult to find traces of flattening.
3, fake stone identification
False blood bloodstone is made of sapphire bloodstone without "blood" or "blood" and painted with red "blood" on it. The identification is mainly based on the characteristics of its "blood", hardness, blood shape, presence or absence of cinnabar minerals, and by means of chemical reagents.
4, local stone identification
Because Changhua Bloodstone is famous and has a long history, it has always been favored by literati. Therefore, the popularity and value are higher than Bahrain's bloodstone. Therefore, there is a problem of the identification of the origin of the bloodstone. Generally speaking, the blood color of Changhua Bloodstone is pure and rich, while the blood color of Bahrain Bloodstone is dark and mostly dark red. The blood shape of Changhua Bloodstone is mostly strip-like, flaky and agglomerate, slightly directional, while the blood shape of Bahrain's bloodstone is mostly cotton-like, cloud-like, non-directional; Changhua bloodstone blood concentration, The serum of Bahrain's bloodstone is scattered; Changhua's bloodstone is not easy to fade, and Bahrain's bloodstone is easy to fade. In addition, there are also differences in texture, hardness, toughness, etc. As long as there is experience, it is not difficult to distinguish them.
5, artificial stone identification
It is generally a "color" opaque plastic, on which cinnabar powder or red organic pigment is used as "blood" and coated with a protective resin, commonly known as "crafted bloodstone". Its identification is mainly based on its "ground" characteristics, and is detected by hot needles and by means of chemical reagents.
