1.Listen to the sound. The sounds heard when you hit the craft glass wine bottle by hand are different. In the wine bottle factory, the tone of crystal material is high, which will have a lingering sound, while the tone of glass products is low and has no echo.
2.Look at the weight of the vessel. For vessels of the same volume, those made of crystal are heavier than those made of glass, and those made of glass are lighter.
3.Look at the refraction.Under the same light, the refractive index of crystal products is higher than that of glass, and can transmit seven rainbow lights,
4.Specific hardness.Crystal is harder than glass, so a trace will be left when you use crystal to scratch the surface of glass, but there is no such trace when you use glass to scratch crystal
5.The main raw materials of glass bottles are natural ore, quartzite, caustic soda, limestone, etc.The glass bottle has high transparency and corrosion resistance.No change in material properties will occur in contact with most chemicals.It has the advantages of simple manufacturing process, free and changeable shape, high hardness, heat resistance, cleanness, easy cleaning, and can be used repeatedly.
