Terp pearls plus a spinner cap turn your banger into a tiny heat and airflow machine, they spread your concentrate into a thinner film, even out hot spots, and usually make your dabs taste better with less waste. This dabbing guide will save you a bunch of trial-and-error, because pearls are awesome right up until you buy the wrong size and they either don’t spin or they try to escape your banger like a prison break.
I’ve been using pearls on and off for about 6 years, and testing them hard the last 2, across standard buckets, auto-spinners, and terp slurpers. I’ve broken a few, launched a few, and yes, I’ve found one on the floor with my sock. Classic.
quartz banger with two ruby terp pearls and a spinner cap in place" style="max-width: 100%; height: auto; border-radius: 12px;" loading="lazy"> Terp pearls (little spheres, usually ruby or sapphire) sit inside your quartz banger. When you use a spinner cap, the airflow makes the pearls rotate, and that rotation pushes your puddle of rosin or live resin around the bucket.
The real win is surface area. A big blob sitting still tends to cook unevenly, which is where you get that half-tasty, half-burnt vibe.
With pearls spinning, your concentrate spreads into a thinner layer. You get more consistent vaporization at lower temps, which usually means better terps and fewer throat-punch hits.
And yeah, heat distribution is part of it too. Pearls act like tiny heat reservoirs. Not magic, but noticeable.
If you want a setup that works on a normal weeknight sesh, not just for Instagram clips, this is it.
I keep all of it on a simple dab station: rig, torch, q-tips, ISO, tool, and my cap. If you’re using a nice glass dab rig, protecting your counter is the boring upgrade that saves you money.
A silicone dab mat or concentrate pad is basically mandatory if you’re running pearls. I like one with a slight lip, because pearls don’t just roll, they migrate.
1. Drop pearl(s) into a clean, room-temp banger.
2. Heat the banger evenly, aim the flame at the sides more than the bottom.
3. Let it cool to your target range (more on temps below).
4. Drop your dab.
5. Cap immediately with the spinner.
6. Sip the hit, don’t rip it like a bong snap.
7. After the hit, swab while it’s still warm, then a second swab with a tiny bit of ISO if needed.
Truth is, the biggest upgrade here isn’t “more pearls.” It’s swabbing every time. Your banger stays clear, your pearls don’t get crusty, and your flavor stays sharp.
Size matters more than material at first. Wrong size equals no spin, splashy oil, or a pearl that wedges itself like it pays rent.
Here’s the cheat sheet I wish I had earlier.
Small pearls (3mm to 4mm)
Medium pearls (5mm to 6mm)
Large pearls (8mm and up)
Most people overdo it. Two pearls looks cool, but it’s not always better.
If you’re dabbing rosin, I lean 1 pearl most days. If you’re dabbing wetter live resin, 2 pearls can help keep it moving without puddling.
Material is where the internet gets weird. People talk like you’re choosing a space shuttle heat shield. You’re buying tiny spheres to spin in hot quartz. Keep it simple.
Ruby (synthetic corundum)
Sapphire (synthetic corundum)
Quartz pearls
Silicon carbide (SiC) pearls
Between you and me, ruby and sapphire are both solid choices because corundum is tough. If you want to nerd out on what “corundum” is and why it’s hard as hell, the Gemological Institute of America has a clean explainer:

And if you’re using ISO regularly, basic safety matters. Good ventilation, no open flames near fumes. NIOSH has straight-to-the-point info:

Spinner caps aren’t all the same. Some are true spinners, some are just carb caps with angled holes that barely do anything.
If your cap wobbles or you see air gaps, your pearls will “jitter” instead of spinning. Annoying.
Standard bucket banger + spinner cap
Auto-spinner banger (built-in spin channels)
Terp slurper / blender
If you’re the kind of person who keeps a pipe clean and organized, slurpers are fun. If you’re not, stay with a bucket and spinner. No shame.
Also, if you’re coming from a vaporizer and you like controlled, repeatable sessions, an auto-spinner banger plus a simple timer feels closer to that “dialed” experience.
This is where pearls really pay off. But they can also help you wreck a banger faster if you run too hot, because they keep the oil moving across the hottest parts of the quartz.
I’m not going to pretend every dab is lab-grade consistent, but here are the ranges that keep me happy:
If you don’t have a temp reader, do a longer cool-down than you think. Most people go in too early.
And pull slower. A hard inhale can pull oil up the walls and into your cap, which tastes like reclaim sadness.
Here’s my routine:
1. After the dab, while warm, dry swab the banger.
2. Let it cool a bit more. Warm, not scorching.
3. Use a second swab with a tiny bit of ISO to polish.
4. If pearls are dirty, drop them in ISO for 10 to 20 minutes.
5. Rinse with water and let them fully dry before the next heat.
I do the pearl soak every few sessions. If you’re dabbing sticky live resin daily, you’ll probably do it more.
And please don’t torch your pearls red hot to “clean” them. You can thermally shock stuff, and it just feels like a good way to turn a $20 accessory into a tiny crack grenade.
Pearls rolling off the table is the origin story of most “I hate terp pearls” takes.
A tidy setup fixes it. Not fancy, just functional.
This is where a good oil slick pad (the actual brand, not generic) earns its keep. Your rig stays planted, your tools stop skating around, and pearls don’t roll into the shadow realm.
If you like using a big bong sometimes and a small dab rig other times, set up your pad so either one fits. A slightly larger mat than you think you need is the move.
If you take one thing from this dabbing guide, let it be this: match pearl size to your banger, use a cap that actually seals, and keep your temps lower than your ego wants. Pearls and banger spinners can seriously improve heat distribution and flavor, but they’re not a cheat code for bad technique.
I still love a simple bucket setup on a clean concentrate pad, with one 6mm ruby pearl and a spinner cap that fits right. Easy. Tasty. No drama.
