[China Glass Network] Everyone knows that to buy products from major international brands, there will be quality and technical guarantees, that is, to look at the brand and recognize the brand. But in addition to this, you can also distinguish crystal and glass in the usual way:
(1) Listen to the sound . The sound heard when the device is hit by a hand will be different. The sound of the crystal product is crisp, and there is a feeling of lingering after the impact of the metal, while the sound of the glass product is heavy and has no echo.
(2), weight . Two items of the same size, crystal products are heavier than glass and lighter than glass.
(3), see the refractive index . In the same light, the refractive index of crystal products is higher than that of glass, which can transmit the rainbow light, and the glass products do not produce colored light.
(4), specific hardness . Crystal is harder than glass, so there is a trace when using crystal to scratch the surface of the glass, but there is no such trace when using glass to scratch the crystal.
