Crystal, ancient water jade, meaning water jade, the ice of the millennium water, also known as the Buddha stone.
Crystal is a crystal of silicon dioxide. Numerous silicon oxides are continuously formed into a crystal structure. The crystal mineral is called quartz. It is usually a hexagonal column and a hexagonal pyramid. It contains various colors when it contains trace elements. Crystal is a spiritual mineral that can bring us good luck and help us get rid of bad luck.
In the natural world, it is hailed as the magic weapon of the elves in the stone. In Feng Shui, the crystal is also known as Feng Shui, because natural crystals condense the essence of the sun and the moon in the hundreds of millions of years, in the various natural elements of the earth's crust. Precipitation (minerals), after a number of years of tempering, form a variety of crystals, each representing different energy frequencies, and producing different magnetic fields and functions, with incredible magic Strength, line with Jingang body, used for spiritual practice, bodybuilding, refining, town house, gathering wealth, praying, charity, removing obstacles, offering Buddha, wishing, spirituality, increasing wisdom, helping people, avoiding villains Wait.
The physical and chemical properties of crystal
1. Hardness: It is Mohs 7, which is equivalent to the hardness of steel shovel, which makes the gemstones such as crisp and fragile topaz, diamond, opal, emerald and so on.
2, cleavage: no. The so-called cleavage refers to the fact that when a mineral is struck, it often cracks regularly in a certain direction to form a smooth plane. According to the complete degree of cleavage, it can be divided into five categories: extremely complete cleavage, complete cleavage, medium cleavage, incomplete cleavage and no cleavage, and crystal is unclear.
3, fracture: shell-like. The fracture is also called a breach. It refers to the irregular cracking of the mineral after being hit, and the rugged surface is called the fracture. According to the shape of the fracture, it can be divided into: shell shape and jagged shape.
4. Specific gravity: The specific gravity of the crystal is 2.56-2.66 g/cm 3 . The weight of the same volume of crystal is 2.56-2.66 times the weight of the same volume of water, and the density of the block variant crystal may be slightly higher.
5, streaks: colorless. The color of mineral powder is called streaks. It can eliminate false colors, weaken the color, and retain the self-color, which is one of the more reliable identification features than the color of minerals.
6. Transparency: transparent and translucent. The degree of light transmission of minerals is called transparency. The crystal's transparent standard is that when light passes through crystal fragments or sheets with a thickness of 1 cm or more, the reflected image can be clearly seen. If the bottom image is not clear enough, only the outline, that is translucent.
7, gloss: glass luster. Gloss is the ability of a mineral surface to reflect light. Observe the luster of the crystal, hold it with your hand, and see the surface reflection by the light projected from the light or window. The brightness of the transparent crystal is related to the gloss.
8. Refractive index: The refractive index of crystal is 1.544-1.553, which hardly exceeds this range. The refractive index refers to the ratio of the sine of the incident angle to the sine of the angle of refraction when the light penetrates into the gemstone crystal from the air and produces a phenomenon of refraction.
9, the melting point of crystal: the melting point of crystal is 1713 degrees Celsius.
