flaschenglas

Flaschenglas is the German word for bottle glass. It is a type of glass specifically manufactured for use in the production of bottles and jars. This type of glass is primarily composed of silica (sand), soda ash (sodium carbonate), and limestone (calcium carbonate). These raw materials are melted together at high temperatures in a furnace.

The resulting molten glass is then shaped into bottles and jars through processes like blow molding or press-and-blow molding. Flaschenglas is known for its durability, chemical inertness, and transparency, making it an ideal material for containing food, beverages, and pharmaceuticals. It is also highly recyclable.

Common colors for flaschenglas include clear (flint glass), green, and brown. These colors are achieved by adding specific metal oxides during the manufacturing process. Green and brown glass offer UV protection, which can help preserve the contents of the container. Flaschenglas is a widely used and sustainable packaging material.
