A freeze pipe is a pipe or bong with a built-in cooling ring that you place in the freezer beforehand. The ring is filled with glycerin – a liquid that retains cold for a long time. The result is a particularly cold, smooth hit, without the need for ice cubes.
How does the cooling work?
A sealed ring or spiral filled with glycerin is integrated into the glass. After one to two hours in the freezer, the ring is thoroughly chilled and transfers the cold to the smoke during use. Unlike an ice bong, nothing melts here – the water is not diluted.
Why glycerin?
Glycerin doesn't freeze as hard as water and retains cold significantly longer. This keeps the freeze pipe cool throughout the entire session. The cooling ring is sealed, so the glycerin never comes into contact with the smoke.
Freeze Pipe or Ice Bong?
Both aim for cold smoke. The ice bong uses ice cubes, which melt and dilute the water. The freeze pipe uses a reusable glycerin ring – no meltwater, always reusable.
Frequently Asked Questions
How long does the freeze pipe need to be in the freezer?
Usually one to two hours, until the glycerin ring is completely chilled.
Is the glycerin dangerous?
No, it is sealed in a closed ring and does not come into contact with the smoke.
How cold does the smoke actually get?
Noticeably colder than with water alone – many describe it as particularly smooth and mild.
