Bong Bowls – Male & Female Glass Bowl Pieces for Clean Airflow & Reliable Fit
A bong bowl (also called a slide bowl or bowl piece) is the component that holds your dry herb and connects directly to your bong. The right bowl improves airflow consistency, reduces ash pull-through, and makes daily sessions easier to manage.
At Croia Glass, our bong bowls are crafted from scientific borosilicate glass for heat resistance, durability, and clean flavor—making them ideal as both primary bowls and replacement bowl pieces.
What Is a Bong Bowl?
A bong bowl is the removable glass piece that fits into your bong’s joint and holds ground dry herb. When you light the bowl and inhale, smoke is pulled through the downstem and filtered by water.
Bowl design, joint size, and joint gender all affect how smoothly your bong clears and how easy it is to control heat and airflow.
Joint Size & Joint Gender Explained
When choosing a bong bowl, you must match both the joint size and the joint gender of your bong. Most bowls are male bowl pieces, designed to fit into female bong joints.
| Joint Size | Joint Gender | Common Use | Notes |
|---|---|---|---|
| 10mm | Male | Mini bongs & compact setups | Smaller airflow path; precise packing recommended |
| 14mm | Male (most common) | Standard bongs | Best balance of airflow and compatibility |
| 18mm | Male | Larger bongs | Faster clears and higher airflow |
Material: Scientific Borosilicate Glass
Because bong bowls are exposed directly to open flame, material quality is critical. Croia Glass bowls are made from scientific borosilicate glass, known for its excellent heat resistance and durability.
This material resists thermal stress, reduces cracking from repeated heating, and maintains structural integrity over long-term daily use.
Popular Bowl Styles
1. Standard Handle Bowls (Anti-Roll Design)
Handle bowls feature a built-in grip that serves two purposes: it allows safe removal during clears and provides an anti-roll function when the bowl is placed on a flat surface. This reduces the risk of the bowl rolling off a table and breaking.
2. Screen Bowls (Reduced Pull-Through)
Screen-friendly bowls are designed to work well with glass or mesh screens, helping prevent ash from being pulled into the water chamber. These are popular for users who prefer finer grinds.
3. Funnel & Martini Bowls (Airflow-Focused)
Funnel and martini-style bowls use a flared interior shape to guide airflow toward the center, promoting more even burning and smoother clears compared to straight-wall bowls.
Bowl Style Comparison
| Bowl Type | Key Feature | Best For |
|---|---|---|
| Handle Bowl | Anti-roll grip, easy removal | Daily use & safety |
| Screen Bowl | Reduced ash pull-through | Cleaner water & downstems |
| Funnel Bowl | Centered airflow | Even burning |
| Martini Bowl | Wide opening, fast clears | Larger packs |
How to Choose the Right Bong Bowl
- Confirm joint size: 10mm / 14mm / 18mm
- Check joint gender: Most bongs require male bowl pieces
- Decide on bowl depth: Shallow for small packs, deep for longer sessions
- Handle vs handle-less: Handles add safety and anti-roll protection
- Replacement use: Keep an extra bowl piece on hand
Croia Glass Tip: A 14mm male glass bowl with an anti-roll handle is the most versatile choice for everyday use.
Cleaning & Maintenance
- Tap out ash after each session.
- Soak in isopropyl alcohol for deeper cleaning.
- Rinse thoroughly and allow to dry fully.
- Using a screen can reduce buildup and extend cleaning intervals.
