A terp pearl (short for terpene pearl) is a small heat-retaining ball used when dabbing concentrates (like wax, shatter, or rosin) with a dab rig.
Here’s what it does and why people use it:
- Evenly distributes heat: Terp pearls spin around inside the banger (the glass bowl part of a dab rig) as you inhale, helping to spread the concentrate evenly across the hot surface so it vaporizes more completely.
- Improves vaporization: Because the concentrate is heated evenly, it prevents hot spots and burning — giving smoother, more flavorful hits and better preservation of terpenes (the aromatic compounds that give weed its smell and taste).
- Increases efficiency: You waste less concentrate because the pearls help vaporize every bit instead of leaving puddles behind.
