Why glass is not always glass

In our postThe three biggest misconceptions about glass drinking straws the term borosilicate glass was already mentioned. Now we would like to explain exactly what this is all about and why HALM is made from another glass.


Borosilicate glass takes its name from the chemical element boron it contains. This has various properties. On the one hand, it is very resistant to various chemicals. On the other hand, it can withstand high temperatures. For glass that is exposed to extreme conditions, for example laboratory glass, boron consequently contributes to greater robustness and durability. So at first glance, borosilicate glass seems like a reliable choice. But watch out, there is also a downside. Of ther high degree of melting of the glass also leads to Problems . Like that high temperatures will be at Not achieved melting of waste glass .

Borosilicate glass disrupts the recycling process. Conversely, this means that the glass cannot be disposed of in the waste glass container. Ultimately, it ends up in the garbage dump and is therefore sustainable and even environmentally harmful..


But we don't want to do this with a product that creates a new garbage problem elsewhere. That is why we made a conscious decision against borosilicate glass and instead chose a glass that would 100 recyclableg and at the same time extremely stable is. And as long as you don't plan to turn your living room into a chemistry lab and come with it HALM performing chemical experiments, you are on the safe side!

Just in case, you can HALM Glass simply im Dispose of the glass container . This protects the climate and saves raw materials because glass can be infinitely often again melt down and new to process . Glass that has been used before even needs lower temperatures than those required for glass production. This means that energy requirements decrease when broken glass is reprocessed. The manufacturing process thus reduces the environmental impact.


Of course, you can assume that you have the glass container for your HALM drinking straws you won't need it so quickly. Because we have ensured that, from the choice of materials to the production process and design HALM extremely stable l is! Our Special glass already has one in itself high strength . This is increased even further by the fact that the glass is baked in an oven at a high temperature using a special process, we also operate this ovenit solar power ! Through this process the loses HALM its tension and becomes more stable. Your HALM also from the ratio between wall thickness and inner diameter. Here not only the optics are right, but also the statics! We'll spare you the mathematical details at this point - but you can remember that your HALM the "golden ratio" Has. The Greeks already used this to build their temples. And if your HALM lasts about as long as the Greek temples, we can be satisfied!


All of these things prevent your HALM shatters into a hundred tiny pieces as soon as it hits the ground. Usually it bounces like a rubber ball on the floor and stays as it is. Sure - one too HALM can break under extreme conditions, because glass remains glass. But in this case you can dispose of this good conscience in the waste glass container and give it a second life. In this sense: #happyslurping .
