Crystal wine glasses and ordinary wine glasses are mainly different in the following four aspects.

1. Raw materials: Crystal wine glasses are made of glass and a certain percentage of lead, while ordinary wine glasses are lead-free glass, both of which differ in strength and transparency.

2. Quality: Compared to ordinary wine glasses, crystal wine glasses are purer, stronger and heavier, and because of the lead content, they are higher in density and heavier in the hand.

3. Charm: Because of the high lead content, crystal wine glasses can reflect and refract light better than ordinary wine glasses, making red wine or white wine more golden or amber tone, improve the quality and taste of wine.

4. Price: Because the production of crystal wine glass is more difficult than the ordinary wine glass, the price is more expensive than the ordinary wine glass.

In short, crystal wine glasses and ordinary wine glasses are similar in shape and use, but there are obvious differences in production materials, quality, flavor and price. Therefore, the choice of wine glasses should be based on personal needs and spiritual pursuits.
