Glycerin & FAQs
What is glycerin?
A non-toxic, food-grade gel used in foods and personal care. Frozen, it holds cold longer than ice and doesn't expand like water, so there's no stress on the glass.
How does the glycerin cooling work?
Smoke travels through a coil surrounded by frozen glycerin. The cold pulls heat out before it reaches you, for hits up to 300° cooler with way less cough.
How long do I freeze it?
One hour is all it takes, and it stays cold for about a session. The glycerin piece can live in your freezer indefinitely.
Will the glass crack from heat or cold?
No. It's thick, lab-grade borosilicate glass made to handle extreme temperature swings.
How do I clean it?
Add 99% isopropyl alcohol and coarse salt (or any glass cleaner), plug the openings and shake. Let it soak 10–15 minutes for a deeper clean, rinse with room-temp water, and let it dry fully before refreezing.
How does shipping work?
Free US shipping on orders $60+, $3.95 under $60, or Expedited for $9.95. Every order ships in a plain, unbranded box.
What if it arrives broken?
Email us photos within 7 days of delivery and we'll replace it. No need to send the broken glass back.
