Stone generally refers to microcrystalline limestone, which is composed of

Second, the main components are different.

1, obsidian

Obsidian is a natural colored glass formed by the sudden cooling of magma from volcanic lava. It is an amorphous gem, and its main component is silicon dioxide (SiO2).

In the process of formation, because the temperature around the lava flow drops rapidly and the cooling rate is the fastest, the magma containing silicon dioxide quickly condenses into blocks, and obsidian generally appears around the lava flow or near the seaside at the foot of the volcano. Because of its unique formation process, the crystal of obsidian also contains 1%-2% water.

2. Bian Shi

Microcrystalline limestone is a kind of carbonate rock deposited by mortar in a calm environment without continuous water flow, which is mainly composed of

Third, the characteristics are different.

1, obsidian

Obsidian has the characteristics of glass, and its cross section is shell-shaped and very sharp. In addition, when obsidian is heated above 1000℃, it will turn into white particles with loose and porous texture due to the loss of water contained in it.

2. Bian Shi

Because its composition is calcite, its toughness is low. Easy to react with acid.

Fourth, the main uses are different.

1, obsidian

Obsidian can be processed into handicrafts. Make scalpel blades.

2. Bian Shi

Microcrystalline limestone is often used to make jewelry, jade and health products.
