Glycerin-filled pipes and bongs use a freezable coil to cool your smoke before it reaches you. Below we cover how they work, how to use them, and answers to the questions we get most.
What Is a Glycerin Pipe?
Aglycerin pipehas a chamber filled with glycerin instead of water. Glycerin freezes without expanding, so you can put the chamber in the freezer without cracking the glass. Once frozen, that chamber cools your hits as the smoke passes through it.
About Glycerin
Glycerin is a non-toxic gel used in everything from soaps to food. In smoking accessories, its value is simple: it freezes solid without expanding, which makes it a safe way to build a cooling chamber into glass. Aglycerin bonguses the same principle at a larger scale.
A glycerin bong has a glycerin-filled section built into the neck or body. It gives you consistent cooling on demand, without the melting and water-level issues that come with an ice catch. Most designs use a removable glycerin neck, so you can freeze it separately and swap it back in when you're ready to smoke.
How Do You Use a Freezable Pipe or Bong
Using a freezable piece takes three steps:
If your piece has a removable glycerin section, separate it from the rest.
Place the glycerin-filled piece in the freezer for 30 minutes to an hour.
Reassemble and smoke as usual — the frozen glycerin cools the smoke as it passes through.
