the material of drink glass bottles

Drink glass bottles are typically made from soda-lime glass, which is the most common type of glass used for packaging beverages. Soda-lime glass is made from a combination of:

1. Silica (SiO2) – The main component, making up about 70-75% of the glass, and giving it strength and clarity.
2. Soda (Na2CO3) – Also called sodium carbonate, it helps lower the melting point of the glass.
3. Lime (CaO) – Provides stability and helps to make the glass more durable.
4. Alumina (Al2O3) – A stabilizing agent that adds to the glass's resistance to breaking.
5. Other additives – Such as small amounts of iron oxide for color, and sometimes magnesium or potassium for specific properties.

This type of glass is preferred for drink bottles because it’s durable, transparent, and can be easily molded into different shapes. It’s also non-reactive, ensuring that it won’t alter the taste or quality of the beverage inside.
