True and false identification of bloodstone
Changhua's bloodstone production is scarce and the veins are almost exhausted, which causes the price to rise every year and is very expensive. Different fake techniques will be used in the market, such as setting up mercury sulfide blocks, impregnating or adding mercury sulfide coatings, and slicing mercury sulfide coatings. Sticking skin, using small pieces of material and wrapped, stone powder and glue high pressure, etc., in an attempt to use fake, fake and real fake way to fish, and profiteering, so how to identify the true bloodstone is very important.
Simple discrimination
1, visual inspection
There are no silver spots on the fake bloodstone, and the color is different in depth and uneven in thickness. The ground has no ribs and no separation. It is too transparent. Under the glare, it can be found that the blood color and stone texture are not hierarchical and coherent.
2, feel
The fake bloodstone has a lighter feel and no cold feeling. When it is lightly tapped on a glass table, its sound is like bakelite, which is too brittle.
3, the knife is lightly scraped
The powder of natural bloodstone after light scraping with a knife is white, and the fake bloodstone is more difficult to scrape the powder, and the powder is still red.
Kistler knowledge - the maintenance of bloodstone
The maintenance of bloodstone is different from other stone materials. The main reason is that bloodstone is a compound of mercury sulfide. Mercury sulfide is easy to oxidize and darken, and it will lose the red color of the original chicken blood. Therefore, the maintenance can keep the red color of chicken blood vivid. Bloodstone is most likely to be exposed to sunlight or light for a long time. Otherwise, it will make the blood color darker and lose its attractive charm. Secondly, it should not be played in the hands for a long time. It will accelerate the oxidation speed due to contact with greasy; be careful when placing it. To avoid the original surface of the stone surface after rubbing with fine polishing, and then hairy; the general collection can be put into the box and the sleeve.
After the blood color of the bloodstone is darkened, the fine layer of fine sand can be used to carefully remove the surface layer, so that the bright red color can be reappeared. However, the pulp of the old chicken blood surface is worn away during the grinding, and the "old blood" becomes "new". "Blood"; when grinding, the original is not concentrated and is a thin layer of stars to scatter blood, but also will lose blood because it is worn away, so be careful when polishing.
