Big 9 Holes Glass Bowl

The Big 9 Holes Glass Bowl is a borosilicate glass bowl designed for dry herb consumption. Built with nine evenly distributed air holes for consistent airflow, this piece fits standard 14mm female joints and delivers smooth, even burns for smokers who want reliable function without overthinking their setup.

Key Benefits

• Nine-hole diffusion pattern — airflow stays even across the bowl for consistent burns without hot spots
• Borosilicate glass construction — handles repeated heat cycles without cracking or clouding
• Compact 27mm diameter — fits comfortably in most 14mm joints without wobbling or feeling oversized
• Lightweight at 7 grams — easy to handle when hot, won't strain your joint over time
• Simple maintenance — smooth glass surface rinses clean with isopropyl alcohol

How It Works

This is a replacement bowl for water pipes with 14mm female joints. The nine-hole design creates even airflow distribution — pack your material, light the surface, and the holes pull air through multiple points instead of channeling everything through a single opening. Result: more consistent burns and less material waste from uneven cherry patterns.

The 16mm height puts the bowl at a comfortable distance from the joint without extending too far. Load capacity sits in the single-session range — perfect for personal use or sharing between two people without overpacking.

Best For

Daily smokers who burn through bowls regularly and need affordable backups. People tired of single-hole bowls that clog or burn unevenly. Anyone looking for a straightforward replacement piece that just works without novelty features or fragile decorative elements.

Specifications

Material Quality

Borosilicate glass is lab-grade material — same stuff in beakers and test tubes. It expands and contracts uniformly when exposed to heat, which means it won't crack from thermal shock when you apply flame repeatedly. Clear glass also lets you see when buildup starts forming so you know when it's time to clean.

At 7 grams, this bowl won't add significant weight to your piece. Lighter bowls mean less stress on the joint connection, especially important if you're using older bongs with wear around the female joint.

Maintenance

Let it cool after use, then soak in isopropyl alcohol (90% or higher works best) for 15-30 minutes. The nine holes can trap resin, so use a pipe cleaner or cotton swab to clear each opening. Rinse thoroughly with hot water and let air dry before your next session.

Fit & Compatibility

This bowl works with any water pipe that has a 14mm female joint. Most small-to-medium bongs and bubblers use 14mm — if you're unsure, measure the opening of your joint or check the original product specs. The male end inserts into the female joint on your piece.

The 27mm bowl diameter is considered standard size. It's not a party bowl, but it's not a one-hitter either — expect 3-5 good pulls depending on how you pack it.

FAQ

Will this fit my 18mm bong?

No, this is a 14mm male joint. If your bong has an 18mm female joint, you'll need either an 18mm bowl or a reducer adapter to make this fit.

How does the nine-hole design compare to a single-hole bowl?

Nine holes create more evenly distributed airflow, which means your material burns more uniformly instead of tunneling through one spot. You'll waste less and get more consistent hits throughout the bowl.

Is this dishwasher safe?

Technically borosilicate can handle dishwasher temps, but we don't recommend it. The nine small holes trap resin that dishwashers won't fully clear. Stick with isopropyl alcohol soaks and manual cleaning for best results.

Can I use this for concentrates?

Not directly — this is designed for dry herb. If you want to dab, you'd need a quartz banger instead. Some people use flower bowls with concentrate sandwich methods (herb-concentrate-herb layers), but that's not the intended use.

How often should I replace this?

Depends on usage and care. With regular cleaning, a borosilicate bowl can last months or even years. Replace it when you notice cracks, chips around the rim, or if the holes become permanently clogged despite cleaning efforts.

Does the nine-hole design make it harder to clean?

It takes slightly more effort than a single-hole bowl because you need to clear each opening individually. A good soak in isopropyl followed by a pipe cleaner run-through handles it — just plan for an extra minute or two of maintenance.

Will this bowl get stuck in my bong joint?

Borosilicate doesn't expand as much as soft glass, so it's less likely to get stuck. That said, resin buildup can create a seal over time. Clean both the bowl and your bong joint regularly, and consider using a small amount of coconut oil on the joint if you're worried about sticking.
