Absolute Zero Glass Pipes

Absolute Zero pipes have a sealed glycerin chamber you chill in the freezer before use, so smoke cools as it passes. Read how Absolute Zero works.

How a Freezer Pipe Works

The glass wraps around a sealed glycerin chamber. Put the pipe in the freezer for a couple of hours and the glycerin chills; smoke then passes through a cold airway on the way to you. Glycerin stays colder longer than water ice and won't crack the glass as it freezes.

How long should I freeze an Absolute Zero pipe?

A couple of hours is enough. Many people simply keep it in the freezer between sessions.

Can I clean a freezer pipe like a normal pipe?

Yes, but let it come to room temperature first. Hot water or a fast soak on frozen glass can stress it.
