We usually associate purity, hygiene, recycling and timelessness with glass as a material. All these qualities make glass ideal when looking for drinking straws without plastic.
But not every glass is the same. Depending on the intended use, various substances are melted together during its production. So, there are a variety of glasses, for instance, one which has properties such as temperature resistance for the future end product, or another used especially for the production of optical lenses.
Many types of glass, especially with special properties, cannot be recycled. Borosilicate glass is used in laboratories because of its high resistance to heat. This is a type of special glasses and it cannot be simply recycled in an old glass recycling plant.
Glass straws also contain different types of glasses used. GlasWerkTrinkhalme be made of soda-lime glass, which is also known as normal glass. It can be recycled endlessly and it is therefore used for preserving jars, bottles and drinking vessels.
We use a special procedure to relax the stems in the production of GlasWerk drinking straws made of glass. This way, the drinking straws are particularly resistant to breakage.
