2. ** Transparency and gloss: ** Lead-free crystal glass still maintains the high transparency and gloss of traditional crystal. This means that the drink can show the most real and clear color in the cup, which enhances the visual enjoyment of the overall drink.

3. ** High compressive strength: ** New lead-free crystal glass has higher compressive strength, making the glass more durable. This feature not only extends the service life of the glass, but also reduces the waste of the environment.

4. ** Wear resistance: ** Lead-free crystal glass is more wear resistant than traditional crystal, reducing the possibility of scratches and wear. This makes the glass still able to maintain a good appearance during a long time of use.

5. ** Design diversity: ** Lead-free crystal glass glasses have more creative space in design, so manufacturers can introduce more unique and beautiful designs. Consumers can choose from a variety of styles that suit their tastes and occasions, thus enhancing the overall beverage experience.
