2. How to Recognize the Quality of Glass Bottles

1. Listen to the sound. When you hit a glass bottle with your hand, you will hear different sounds. In a wine bottle factory, the tone of crystal material is higher, and there will be a feeling of aftertone winding around the beam, while the tone of glass products is lower and no echo.

2. Look at the weight of the utensils. For the same volume of utensils, the crystal material is heavier than the glass material, and the glass is lighter.

3. Look at the refractive index. Under the same light, the refractive index of crystal products is higher than that of glass products. It can transmit rainbow light, but the glass products can not get color light. The quality standard of glass bottles can be analyzed and judged from the product quality standard of the manufacturer.

4. Specific hardness. Crystal is harder than glass, so when you scratch the surface of glass with crystal, you will leave a trace, but when you scratch the crystal with glass, there is no such trace.
