When you buy a crystal ball, you can see that the sphere is very large at first glance, and then you can surely be a glass imitation without hesitation. Natural crystal balls are generally small in diameter, usually 2 cm to 5 cm, pure crystal balls with a diameter of 10 cm are the top grade in natural crystal balls, and crystal balls with a diameter of 20 cm are very rare. So seeing the big crystal ball must be an imitation. Below, Glass Ball Manufacturer will share the difference between glass ball and crystal ball:
1. Look at the inclusions
Due to the influence of the natural crystal generation environment, natural crystal balls generally have cotton flocs or cracks, or mineral inclusions. These cotton flocs are gas-liquid inclusions observed with a magnifying glass. Mineral inclusions have certain shapes and various types. Color; bubbles or agitated texture like agitated syrup inside the imitation. So whenever you see bubbles and agitated textures, they must be imitations.
2. Feel
Whether it is in hot summer or cold winter, natural crystal ball touches the hair and cools, while the imitations are warm. But don't touch it for a long time, the first feeling is the most accurate. Over time, I'm afraid I can't figure it out.
3. Watch double shadows
Put the crystal ball on the paper with words or lines and observe the changes of the words or lines below. If you see the double shadow of the words or lines, it is a crystal ball, otherwise it is an imitation. Be sure to turn the sphere to observe, because crystal is a heterogeneous body, and glass is a homogeneous body. However, according to the crystal structure of the crystal, when viewed in the direction perpendicular to the optical axis, it is also unchanged like glass. Rotating the sphere can avoid the direction perpendicular to the optical axis, so as to avoid wrong judgment.
