In recent years, with the rapid improvement of modern technology, the ancient and traditional glass industry has been renewed, and various glass products with unique functions have come out one after another. These glasses can not only play a traditional light transmission effect, but also play an irreplaceable role in some special occasions. If you want to know the difference between crystal and glass red wine glasses, you will know after reading this article.
1. How to distinguish whether a red wine glass is a crystal or a glass
1. Compare the price
The price of the crystal glass is more expensive than that of the ordinary wine glass. The crystal content of the red wine glass determines its price and quality.
2. See clarity
High-quality wine glasses usually have thinner walls and better appearance. Crystal glasses can reflect the wine color more accurately and clearly.
3. Touch the hardness of the cup wall
Crystal cups generally have stronger hardness than ordinary glass and are more resistant to wear.
4. Look at the refractive index
Crystal can absorb luster, so when you rotate the crystal cup against the light, the crystal has birefringence, like exquisite handicrafts, while ordinary glassware has no gloss and no refraction.
5. Listen to the sound
When tapped lightly, the glass makes a “click, click” sound, and the crystal is a light and brittle metal sound, accompanied by a buzzing echo.
6. Body feel
The coolness of the crystal is good, but the glass will feel warm when you hold it in your hand, and the heat transfer speed is fast!
7. Smell the aroma
The wine in the crystal glass smells very fresh, clean and strong. The wine in the glass glass has become stuffy and less intense.
8. Weight measurement
For two wine glasses of the same size, the crystal product is heavier than the glass.
2. How to distinguish whether it is a glass or a crystal cup
1. Spread the palm of your hand to hold the bottom, tap with a metal spoon, and you will hear different sounds. The sound of crystal is clear and lingering, while the sound of glass products is dull and no echo.
2. Weigh the weight. For two items of the same size, the crystal product is heavier than the glass.
3. Look at the color. The crystal is transparent and dazzling, and the brightness of the glass is insufficient. Under the same light, the refractive index of the crystal product is significantly higher than that of the glass.
4. Specific hardness. The hardness of crystal is 7, while the hardness of glass is about 5.5. If the glass is scratched with the fresh edges and corners of the wafer, scratches will appear on the glass.
5. Tongue feeling. Lick the crystal with the tongue to have a cold feeling, and the glass to have a warm feeling
