Because the ore of the ice crystal obsidian itself is a rare ore resource, in the 10,000 tons of obsidian ore, only one hundred grams of ore can reach the ice crystal level to become ice crystal obsidian. So now there are a lot of glass products on the market to fake, using glass as ice (ice crystal) obsidian products to sell, today we will subdivide the difference between ice (ice crystal) obsidian and glass.
Ice (ice crystal) obsidian and glass
1. Obsidian, also known as the Tokachi Stone, is a naturally occurring glass. Its cause is because the volcanic lava cools and condenses rapidly, and the crystal structure does not have enough time to grow. Because the lava flow cools at the fastest rate, obsidian is usually found on the periphery of the lava flow. Main components: silica, hardness: 5, specific gravity: 2.339-2.527, refractive index: 1.48-1.51, water content 1-2%, chemical composition is SiO2 (H2O).

1. Ordinary glass is mainly amorphous silica (SiO2), that is, quartz, or the chemical composition of sand. The pure silica melting point is 2000 degrees Celsius. Therefore, two materials are generally added when manufacturing glass: sodium carbonate (Sodium Carbonate, Na2CO3, that is, soda powder) and potassium carbonate (potash, potash). This silica melting point will drop to about 1000 degrees. However, since sodium carbonate dissolves the glass in water, it is usually necessary to add an appropriate amount of calcium oxide, CaO, to make the glass insoluble in water.

Ice species [ice crystal] distinction between black ochre and glass
Enlarged inspection of [Ice Crystal Obsidian Certificate]: visible natural inclusions. Main stone name: Black Rock.
[Glass certificate] magnification check: internal clean or flowing structure, air bubbles. Main stone name: glass flower piece or glass pendant.
Ice (ice crystal) obsidian and glass color distinction
The color of ice crystal obsidian: ice crystal obsidian is dark brown and black under natural light, transparent. The color is more positive. Strong gloss.
The color of the glass made by people: the color is lighter and lighter brown, and there is no difference in different light. The color is dark and dull.
Wearing obsidian has a certain evil effect, but if you buy a good obsidian, you need to polish your eyes.
Non Woven Felt For Automotive Interior
What kind of fabric is used for car upholstery?
There are many kinds of car fabrics, but the most common is car non woven fabrics. Automotive non woven fabrics are a new generation of environmentally friendly materials, which are moisture proof, breathable, flexible, lightweight, flame-retardant, heat-insulating, non-toxic, tasteless, and non-irritating. Non woven fabrics are widely used in automobiles, such as car trunks, car seat cushions, car ceiling sound insulation, etc.
