Crystal glass usually refers to a cup or wine glass made of lead-free crystal glass for drinking. With the popularization of technology and craftsmanship, crystal glass has been used as a teacup and has become the favorite of fashion people in the new era; the other is a common crystal Wine glass. Lead-free crystal is very popular among consumers and processing manufacturers because of its higher transparency and brightness; then, what is a crystal cup? What is the difference between a glass and a glass? How many people know about this? Below, the editor will tell you the difference between crystal cups and glass cups, hoping to help everyone.
What is a crystal cup
Crystal cup is also a kind of glass, the main ingredient is also silica, but lead, barium, zinc, titanium and other substances are introduced into it. Because this kind of glass has high transparency and refractive index, and its appearance is smooth and crystal clear, it is called crystal glass.
If lead is introduced, it is lead crystal. The introduction of barium, zinc, titanium and other substances is lead-free crystal. How to distinguish between the two?
One by hand. Because the thermal conductivity of crystal is stronger than that of glass, it should be cooler when touching the crystal by hand than touching the glass.
Second, look at the hardness. Natural crystal has a hardness of 7 and glass has a hardness of 5, so crystal can scratch glass.
Third, look at refraction. Lift a crystal cup and rotate it against the light, you will find that it is like an exquisite handicraft, pure white, transparent, reflecting the charming colorful light, because crystal can absorb luster and even ultraviolet rays, while ordinary glassware There is no gloss, and no refraction.
Four listen to the voice. Lightly tapping or flicking the utensils with your fingers, crystal glassware can make a light and brittle metal sound, and a beautiful residual sound is rippling in the breath, while ordinary glassware only has a dull “click, click” sound.
The difference between crystal cup and glass cup
The wine glasses available on the market can be divided into glass and crystal in terms of texture. What is the difference between these two wine glasses?
First of all, the most direct manifestation is the price. The price of crystal glasses is more expensive than ordinary wine glasses. Especially crystal wine glasses from abroad, such as Italy and Austria, are both high-quality crystal glass producers.
Secondly, due to the different raw materials of the two, the effect of wine tasting is also different, because the clarity of crystal is much higher than that of ordinary glass. When viewing the color of wine, the crystal glass can reflect the wine color more accurately and clearly.
In addition, crystal cups generally have stronger hardness than ordinary glass and are more resistant to wear. A high-quality crystal cup should have a high degree of clarity and a hard outer wall. It will make a crisp sound when colliding with each other. After the collision, hand the cup to your lips quickly and you will feel the shock of an electric shock. kiss”.
