Distinguishing method between crystal cup and glass cup

We often come into contact with various types of glass materials in our daily life. In addition to the traditional flat glass, there are also glass materials with special properties such as ultra-white glass, high-borosilicate glass, and common materials such as insulating glass and laminated glass.

In fact, the crystal cup is also a kind of glass cup, but the crystal is silicon dioxide crystal, and the glass is a mixture containing silicon dioxide. Therefore, the crystal has relatively high transparency and refractive index, and its appearance is bright and clear.

The crystal cup and glass cup can be felt by hand, because the thermal conductivity of crystal is stronger than that of glass, so it should be cooler to touch crystal with hands than touch glass.

Look at refractivity: lift a crystal cup and rotate it against the light. You will find it is like an exquisite handicraft. It is white and transparent, reflecting the charming multicolored light. Because crystal can absorb luster, even ultraviolet rays, while ordinary glassware has no glossiness, let alone refractivity.

Listen to the sound: gently tap or flick the glass with your fingers, the crystal cup can make a light and brittle metal sound, while ordinary glassware can only make a dull “click, click” sound.

It can be seen that the crystal cup is really much better than the glass cup. It feels different to drink with the crystal cup. In terms of price, the crystal cup is much more expensive than the glass cup, and sometimes it is really a price for a price.
