The difference between crystal cup and glass cup

Crystal cups and glass cups are essentially the same. The crystal here refers to glass cups, but the production process is different. The ingredients contained are all silicon dioxide, but some other metals are added to the crystal cups, such as lead, barium and other metals. This can give people a feeling of higher transparency and refractive index, and the appearance appears to be more crystal clear, so it is called a crystal cup. The thermal conductivity of the crystal cup will be better. Its hardness is relatively high. From the appearance point of view, the crystal cup is of course better.

The difference between crystal cup and glass cup

1. Crystal cup is also a kind of glass cup. Its main component is also silicon dioxide, but it also contains lead, barium, zinc, titanium and other substances. Because this kind of glass has high transparency and refractive index, and its appearance is smooth and crystal clear, it is called crystal glass.

2. Crystal has better thermal conductivity than glass, so it should feel cooler when you touch crystal than when you touch glass.

3. Look at the hardness. The hardness of natural crystal is 7 and the hardness of glass is 5, so crystal can scratch glass.

4. Look at the refractive index. Hold up a crystal glass and rotate it towards the light, and you will find that it is like a fine piece of handicraft, pure white, translucent, and refracting charming colorful light. That's because crystal can absorb light and even ultraviolet rays, while ordinary glassware has no glossiness and no refractive properties.

5. Listen to the sound. Crystal glassware can emit a crisp metallic sound when you tap it gently or tap it with your fingers, and a beautiful lingering sound ripples through the air, while ordinary glassware only makes a dull "click, click" sound.

Which is better, crystal or glass? When it comes to wine glasses, crystal is of course better. Why choose crystal cup? 1. Clearer Crystal cups have good light transmittance. Cups made of this material have a good refraction effect on light and look very pleasing to the eye when tasting wine. 2. Lighter and thinner The crystal cup has high hardness, so the cup made is strong enough, and the cup wall can be made very thin. The whole cup is very light. When tasting wine, both men and women can easily and elegantly raise the glass to drink. 3. Crisper: Clinking glasses when drinking is a common habit for wine tasting, and the sound of a crystal glass is louder and crisper than that of a glass glass.
