Pattern glass gets its unique texture and decorative appeal from a specialized production process. Here’s a concise breakdown:
1. Raw Material Preparation
Key ingredients include quartz sand, soda ash, feldspar, and limestone. These are carefully mixed and melted in a furnace to create molten glass.
2. Glass Melting
At around 1500°C, the mixture is heated until it forms a uniform glass liquid, ready for shaping.
3. Embossing and Shaping
4. Cooling and Annealing
The glass is gradually cooled in an annealing kiln to release stress and improve durability.
5. Cutting and Finishing
The glass is cut to size and polished as needed. Optional processes include tempering for strength or coating for added functionality.
Optional Finishing Processes:
Tempering: Increases impact resistance.
Coloring or Coating: Enhances decorative appeal or adds functionality (e.g., UV protection).
Features of the Manufacturing Process
Customized Pattern Designs
By altering the roller engravings, a wide variety of patterns can be created, such as striped patterns, water ripple textures, or fabric-like designs.
Precise Temperature Control
The temperature of the molten glass directly influences the clarity of the pattern and the product’s consistency, requiring advanced equipment and expertise.
Optimized Annealing Process
The annealing stage is critical for ensuring the strength and durability of the final product, with strict control over time and temperature curves.
