How Glass is Made: From Sand to Premium Bottle

Glass is one of the oldest and purest packaging materials in the world. It is 100% recyclable, chemically inert, and ideal for storing spirits and food. But how exactly are those transparent and durable bottles you see in the Glavero.eu catalog created?

1. Glass Ingredients – Natural and Simple

• Quartz Sand (Silica): The primary material that forms the glass structure.
• Soda Ash: Lowers the melting point of the sand, making the process more energy-efficient.
• Limestone: Provides chemical durability and prevents the glass from dissolving in water.
• Cullet: Recycled glass that accelerates melting and protects the environment.

2. Melting and Forming

Raw materials are melted in furnaces at temperatures above 1500°C. The molten glass is cut into precise drops and fed into forming machines, where air pressure creates the desired shape.
