1. Clarity

Glass glass and crystal glass raw materials are different, which also leads to the two wine tasting effect is not the same, mentioned above, crystal glass material and natural crystal similar, so its clarity is higher than ordinary glass, so in wine tasting, crystal glass more accurately and clearly reflect the color of wine.

Second, refraction

It said above that lead glass products have a high refractive index, so when the crystal cup is held up to the light and rotated, you can see that it refracts five colors of light, and ordinary glass glasses have no gloss and no refraction.

Third, hardness

Crystal wine glasses are generally stronger and more resistant to wear than ordinary glass glasses.

4. Feel

The thermal conductivity of crystal is stronger than that of glass, so touching a crystal glass by hand will be cooler than touching a glass glass, and the cold feeling will last longer.

5. Sound

When gently tapped or flicked with your fingers, crystal wine glasses will emit a crisp metallic sound and have a buzzing aftersound, while ordinary glass glasses will emit a dull sound. And after the collision, the glass is quickly passed to the lips, and the vibration can be felt, which is what people describe as the "crystal cup kiss."

6. Weight

Under the premise of the same size, crystal wine glasses are heavier than glass wine glasses.
