Simple identification method:
1. Listen to the sound and hit the container with your hand. The sound of crystal is crisp and clear, just like the lingering sound after hitting metal, while the sound of glass is dull and echoless< /p>
2. Weigh the weight, crystal is heavier than glass
3. Specific hardness, if you scratch the glass with crystal, scratches will appear on the glass, but if you scratch the crystal with glass, the crystal will not appear
< p>The difference between crystal and glassCrystal and glass have very similar appearances, but they are two completely different substances. The main differences are as follows:
1. Different materials
Crystal is a crystal of silica, while glass is just a molten mixture containing silica.
Two. Different effects
Glass only has a decorative effect, while crystal not only has a decorative effect, but also has a piezoelectric effect and has special health care effects.
Three. Prices are different
The unit price of crystal is several times or even dozens of times higher than that of glass.
Four. Different physical properties
1. Crystal is a crystal with a high hardness (Mohs 7), while glass has a lower hardness (Mohs 5.5). Crystals can scratch marks on glass, but not vice versa.
2. Crystal is a crystal with good thermal conductivity. It feels cool when licked with the tip of the tongue. The glass, on the other hand, appears warm.
3. Use a polarizer to distinguish, crystal can transmit light, but glass cannot.
We can easily distinguish crystal and glass based on their different physical properties.
Five. Different processing techniques
Glass can be hot cast, saving materials, labor and low cost.
Crystal is a crystal and cannot be reversed after heating and melting. Therefore, hot casting cannot be used, and only cold processing methods such as cutting and grinding can be used. It consumes materials and labor, and the cost is high.
Crystal has high hardness and is not easy to wear. Glass has low hardness and is easily scratched.
Crystal has good stability and will not change color after long-term use. Glass is prone to yellowing.
