Borosilicate Glass Bong Downstem | Basic Slit | Choose Size

A downstem is a crucial component of a bong, functioning as a conduit between the bowl and the base. The bowl is where the herb or tobacco is placed and ignited, and the base is typically a water-filled chamber that cools and filters the smoke.

A borosilicate glass downstem, specifically, is a downstem made from a type of glass that is highly resistant to heat and thermal shock. Borosilicate glass is a popular material for downstems because it's durable, non-toxic, and can withstand the heat of burning material without deforming or releasing harmful substances.

In the typical bong setup, the downstem's top end extends into the bowl, while its bottom end is submerged in the water in the base of the bong. When a user inhales through the bong's mouthpiece, the suction draws the smoke from the burning material in the bowl, down through the downstem, and into the water. The water cools the smoke and also filters out some of the heavier particles and toxins, making the smoke smoother and less harsh when inhaled.
