Glass bottles are a common packaging material used in various industries. The process of making a glass bottle begins with raw materials, such as sand, soda ash, limestone, and cullet. These materials are blended together and melted at high temperatures to form molten glass.The molten glass is then fed into a machine called an IS machine, which shapes the glass into a bottle. The IS machine consists of sections that perform different functions such as forming the neck, body, and base of the bottle. The machine also has molds that shape the glass into the desired size and shape.
