A bong is a water pipe where smoke is filtered and cooled by water before you inhale it. The principle is centuries old, and its effect is still convincing today: cooler, smoother, cleaner draw than a dry pipe or a joint. In the scene, the bong is cult – and if well-made, a piece of craftsmanship that lasts a lifetime.
How does a bong work?
The core is water filtration. When you draw, the smoke is directed through the water chamber, where it cools down and some of the coarse particles and water-soluble substances are trapped. The result is a noticeably smoother draw that doesn't scratch your throat and lungs as much. Anyone who has ever drawn from a well-made glass bong understands why many people want nothing else.
The construction of a bong
As different as bongs may look – the components are almost always the same:
- Water chamber – the bulbous part where the water sits and filters.
- Tube with bowl – this is where the smoking material goes. The bowl is detachable and can be replaced.
- Downstem – directs the smoke into the water. As a diffuser with slits, it ensures finer bubbles and better filtration.
- Joint – the standardized connection, usually NS 14 (14.5 mm) or NS 18 (18.8 mm). A clean precision joint determines airtightness and draw.
- Carb hole – an optional side hole (Carb Hole) that you use to control the draw.
- Mouthpiece – the upper rim from which you draw.
What materials are available?
The most important factor for quality and taste is the material:
- Borosilicate glass – the gold standard. Heat-resistant, taste-neutral, durable. Practically all high-quality bongs are made from it.
- Acrylic – cheap and robust against falls, but the taste suffers and scratches accumulate.
- Silicone – unbreakable and travel-friendly, functional but a compromise.
At EHLE., we work with thick-walled borosilicate glass out of conviction – because there is simply no better choice for smoking behavior and durability.
The most important types of bongs
- Cylinder bong – straight tube, clear draw, easy to clean.
- Beaker bong – bulbous stand shape, more volume, tip-resistant.
- Percolator bong – with an additional percolator for even finer filtration.
- Ice bong – with notches for ice cubes that cool the smoke extra.
Why craftsmanship makes the difference
There's a world of difference between an off-the-shelf bong and a handcrafted glass bong. Wall thickness, cleanly worked joints, a well-designed diffuser – these decide whether a bong just works or feels really good. At EHLE., most of our products are made directly in our workshop in Germany, and many pieces pass through Thomas' hands. Not an anonymous mass-produced look, but glass with character – right down to the genuine unique piece.
How do I clean a bong?
Regular cleaning keeps the taste pure and the glass clear. Empty old water after each session, and thoroughly rinse with suitable cleaning accessories once or twice a week.
Frequently asked questions
What joint size do I need?
The most common are NS 14 and NS 18. It's important that the bowl, downstem, and bong have the same size. Sizes can be combined using adapters.
How much water should be in the bong?
Enough so that the downstem stands one to two centimeters in the water. Too little filters poorly, too much splashes into the mouthpiece.
Glass or acrylic – which is better?
For taste, durability, and feel, clearly glass.
