When considering buying a cup, there are other factors to consider in addition to the material. Glasses are usually more affordable, easy to replace, and suitable for daily use at home. They are also suitable for holding hot drinks, as glass generally withstands high temperatures better. However, because of its unique production process and noble appearance, crystal glasses are often regarded as a luxury tableware choice, especially in formal banquets or special occasions.

In addition, because the crystal glass contains more lead oxide, its refractive index is higher, so it shows a more unique optical effect. This allows the crystal cup to create a beautiful refraction in the light, adding a sense of ritual to the meal. However, it should be noted that if you pay more attention to the practicality and durability of the cup, you may be more inclined to choose ordinary glasses.
