In particular, those containing chromium have a greenish green color. Streak color is colorless. The flashing of the riverbed into three pieces is likely to be confused with placer, but is easily identified by specific gravity. Fine fibrous crystals are used to distinguish them as biotite. It is used as an electrical insulator because it resists fire and is an electrical insulator. It is very widely distributed and is produced among various rocks except volcanic rocks. It is also produced by decomposition of other minerals. It is known that the quality is good in Canada, India and the Russian Federation.

Biotite added as co-additive powder has a chemical composition of K (Mg, Fe) 3AlSi3O10 (OH) 2 and forms a plate or an impression and often shows hexagonal or rhombohedron. The cleavage is perfect at the bottom and the flake is elastic, which is smaller than the gold mica. It is black, brown, green, black, etc., and the cleaved surface has a pearl luster, and sometimes has a metallic luster. Hardness 2.5-3.0, specific gravity 2.7-3.1. The distribution is very wide and is produced by many igneous and metamorphic rocks and is not uncommon in sedimentary rocks. In pegmatite, huge biotite crystals can be obtained.

It is a plate-shaped crystal but sometimes forms a rod-shaped crystal. There is a complete cleavage at the bottom and the elasticity is strong. Brownish-brownish-brownish reddish brown, pearlescent or submetallic luster, sometimes copper-like reflections. It may also contain rutile, and in light of it produces six star-shaped glows. Refractories are used as electrical insulators. It is produced together with limestone, graystone, and bituminous granite at the contact point of limestone or limestone with igneous rock. It is produced in large quantities in Canada, the United States, Finland and Norway. In Korea, it is produced in the North and Yellow Seas.

Iron mica added as auxiliary additive powder has hardness 3.0 and specific gravity 3.1. Black-blackish brown, almost opaque to the naked eye. There are Geumgwang polish or glass gloss, and it also shows pearl luster. Less elasticity than biotite. It is contained in granite and island rocks, and is also produced in pegmatite.

In addition, the chemical composition of the olivine added as auxiliary additive powder is (Mg, Fe) 2SiO4. There are columnar decisions, but some are not clear. Olive or yellowish brown to grayish red, transparent or translucent, streaky white. Hardness 6.5-7, specific gravity 3.2-3.4. It shows a crack in the shape of a clam shell. It is one of the minerals that are easy to change and often turns into serpentine along its periphery or cracks. It is usually produced as a semiclinic rock of volcanic rocks such as andesite and basalt. It is also produced as a nodule of granular aggregates in volcanic rocks, and is often contained in plutonic rocks such as olive rocks. Fine ones are used as jade.

The chemical composition of the fluoride added as auxiliary additive powder is W1-p (X, Y) 1 + pZ2O6. It is a silicate containing calcium, magnesium, iron (II), iron (III), titanium, aluminum, etc., and has a complicated component. It forms a decision of a square column or a hexahedral column, and is often twin. There is a complete split in two directions parallel to the major plane and intersected at nearly 90 °. This allows the splitting angle to be distinguished from hornblende of 120 ° and 60 °. White, light brown, green, grey-green, glassy glossy. Streak colors are white, light brown, light green. Hardness 5-6, specific gravity 3.2-3.6. About 20 kinds are known, and there are common ore, ore, ore, alkali, sapphire, laxite, eze, and ethirine. Mild ore, or iron ore, etc. belong to the orthorhombic system and are called orthogonal. Others belong to the monoclinic system and are called monoclinic. Volcanic rocks such as andesite and basaltic rocks are semi-coated and widely distributed.

In addition, the activated carbon has excellent porosity due to its porosity.

In the above, 8-12 wt% of the fluorescent substance is mixed with 88-92 wt% of the natural stone powder.

Therefore, the fluorescent material absorbs and reflects the illumination light of the vehicle at night, thereby making sure the driver recognizes the boundary stone.
