Vodka Glass Bottle

The primary raw materials for making glass bottles are: Silica Sand, Soda Ash, Limestone, Recycled Glass (Cullet).

The raw materials are mixed together. This batch mixture is then heated in a furnace to 1700°C (3092°F) to form a molten glass mixture.

The molten glass is then cooled to a more manageable temperature (around 1,000°C or 1,800°F) in a process called conditioning. This helps achieve a uniform temperature and consistency.
By refining the molten glass to remove air bubbles and impurities, it ensures the glass is free from defects and has a uniform consistency. The refined mixture is cooled slightly to workable temperature, which is crucial for the forming process.

The refined and conditioned glass mixture is shaped into bottles using one of two methods:
① Blow-and-blow method: This method is usually used when manufacturing narrow glass containers and those that require various neck thicknesses.
② Press-and-blow method: This is the most widely used process for manufacturing glass bottles and is typically used to manufacture wide-mouth glass bottles and glass jars.

Once the formation process is completed, the glass containers are transferred to an annealing lehr which gradually cools the glass products down to relieve internal stresses that could lead to shattering or cracking. This process ensures the strength and durability of the glass.

Each bottle is rigorously inspected to check for defects such as cracks, bubbles or inconsistencies in thickness. Any bottle showing imperfections such as misshapen areas, cracks and bubbles is taken out of the batch and recycled.
