What are terp pearls and how do they work?
Terp pearls (also called dab pearls or banger beads) are small balls — usually quartz, commonly 4–6mm — that you drop into your banger before heating.
What they do When air spins through the bucket (with a spinner cap, or by moving a bubble cap), the pearls spin with it. As they roll they do two jobs:
- Spread heat — the hot pearls store heat and pass it to the concentrate continuously, so the puddle vaporizes evenly instead of burning at one hot spot.
- Spread the concentrate — rolling pearls smear the puddle into a thin, fast-vaporizing film.
The result: fuller vapor at lower temperatures, which means better flavor.
