Borosilicate glass is a particularly heat-resistant quality glass – the same as that used in laboratories. For bongs, pipes, and glass art, it is the gold standard because it withstands heat, temperature changes, and everyday use without weakening.
What makes borosilicate glass special?
The crucial component is boron trioxide. It ensures that the glass hardly expands when heated – and that is precisely what makes it so resistant to temperature fluctuations. Where normal glass cracks with a rapid change from hot to cold, borosilicate glass remains stable.
The advantages at a glance
- Heat-resistant – withstands high temperatures and rapid changes.
- Taste-neutral – releases no substances, does not falsify the aroma.
- Durable – processed with thick walls, it lasts for many years.
- Malleable – can be formed into precise functions and true art.
Why EHLE. relies on borosilicate glass
For us, there is no compromise when it comes to material. Thick-walled borosilicate glass is the basis for clean smoking behavior, precise grinds, and pieces that last a lifetime. Most of our glass art is made from it – directly in our workshop in Germany.
Frequently Asked Questions
Is every glass bong made of borosilicate glass?
No. Cheaper models use simpler glass that cracks more easily. Look for thick-walled borosilicate.
Can borosilicate glass still break?
Yes, with strong impacts – it is more break-resistant, but not unbreakable. However, it is very robust against temperature.
How can I recognize good borosilicate glass?
By the wall thickness and the clean workmanship – see wall thickness.
