How is the crystal ball made?

A process, fine grinding crystal. The plate for fine grinding is the same as the plate for coarse grinding, except that the added emery is fine (commonly known as fine sand, hereinafter referred to as fine sand), and the coarse sand on the plate needs to be washed before fine grinding. Slightly polish the disk surface and fine seams with a special grinding disc, which is the nursing action of the grinding disc. Dip the brush in water and clean it carefully. ?

In the process of fine sand and coarse sand, the gestures are exactly the same as those of Fang *, but the thickness of emery used is slightly different. In the process of grinding, we should observe while grinding. Fine sand is a necessary action to remove sand holes and scratches left by coarse sand on the crystal surface.

1, feel the energy? Rock crystal, nourished by the essence of heaven and earth for hundreds of millions of years, contains cosmic consciousness and radiates cosmic energy. If you hold it in your hand and experience it carefully, there will be a slight vibration like electricity, which is refreshing. The synthetic crystals have the same molecular formula, but grow rapidly. It was published in the laboratory in just a few hundred days, and it has not absorbed and accumulated the cosmic energy well. It is only used as a material and can't be compared with crystal gems at all. There is also a kind of "crystal glass", also called crystal, which is mostly imported from the Czech Republic and Austria. In fact, these beautiful things are just ordinary glass with lead content of 5-35%, which looks transparent and bright, with increased specific gravity, decreased hardness and no energy at all. Melted crystals, most of which are imitation crystal balls above 100mm, are made by melting quartz powder in a high-temperature furnace and extracting impurities to obtain pure molten crystals. You can only see through it like glass from any angle.

2. Look at the content? When choosing white crystals, the surface luster of rock crystals is mostly "light blue" and contains "inclusions". Some of them are bright pancakes, which can clean human diseases, and some are like clouds and mountains. Because of its natural formation, its shape is random, powerful, strange and beautiful. The appearance of intraocular lens looks very pale and transparent, and some of them also contain regular oval flocs, which is the formation layer of intraocular lens. Synthetic crystals are mostly made of beads or planes, such as pen pendants and ultrasonic intaglio Buddha brand pendants. "Crystal glass" and "refined crystal" have no inclusions at all.

3. Crystal has birefringence. Under the polarizer, the crystal will show a change of light and shade every 90 turn, and the light below can be transmitted. Moreover, the synthetic crystal is dim, and the light under it is opaque. Crystal glass and fused crystals are even more bleak.

4. Crystal stone is usually heavier, and crystal stone of the same size will be heavier than artificial crystal.

5. Generally, a natural crystal ball over 50mm will have a "double shadow" when the ball is on a line, while an artificial crystal ball is "single refraction", so the line under the ball can be clearly seen. Secondly, hold it with your hand and look at your fingerprints through the sphere. If you can see your fingerprints clearly, it is an artificial crystal ball. If it looks a little fuzzy and there is a "ghost" on the edge of the finger, it is a natural crystal ball. The bigger the sphere, the easier it is to distinguish.
