2″ 18mm Fume w/ Color Glass Flower Bowl

The 2″ 18mm Fume Glass Flower Bowl is a compact replacement bowl built for 18mm female joints on water pipes and bubblers. Short, functional, and available in multiple color accent options, this bowl keeps your setup running when you need a spare or want to swap styles without much commitment. The fumed glass finish develops character over time, shifting in tone as you use it.

Key benefits

• Fits standard 18mm joints — Works with most mid-to-large water pipes and bubblers using 18mm female connections, no adapter needed
• Frosted joint for a secure seal — The ground glass joint grips snugly to reduce wobble and air leaks during your session
• Fume glass finish with color accents — Subtle color linework adds character without being flashy, and the fume base changes tone over time with use
• Compact 2-inch size — Short enough to keep a low profile on smaller rigs or tabletop pieces without getting in the way
• Solid backup option — Keep a spare on hand or rotate colors depending on your mood

Best for

This bowl works for anyone running an 18mm water pipe or bubbler who wants a simple, functional replacement that gets the job done. If you break bowls semi-regularly, like to have backups around, or just want to switch up the look with different color accents, this fits the bill. The compact size suits smaller rigs where a longer bowl would look out of proportion, but it seats just fine on larger 18mm pieces too.

How it works

Slide the frosted 18mm male joint into your water pipe's female joint until it sits snug. The ground glass creates a natural seal, so you won't need an adapter or grommet on a properly sized piece. Pack your flower into the bowl without overpacking — leave some room for airflow or you'll end up pulling hard and getting nowhere.

The fume glass is where this bowl gets interesting. Fumed glass is made by vaporizing precious metals (usually silver or gold) onto the glass surface during production. This creates that iridescent, color-shifting effect you see when light hits it. As you use the bowl and resin builds up behind the glass, the colors become more pronounced and the fume takes on a richer, darker tone. Some people call it "breaking in" the piece — the more sessions, the more character it develops.

When you're ready to clear your hit, lift the bowl out by the stem to let air flow through. The short 2-inch length makes it easy to grip without fumbling, even when things get a little hazy.

Specifications

Fit and compatibility

This bowl is designed for 18mm female joints, which is the most common size on medium to large water pipes, bubblers, and beaker-style bongs. It won't fit 14mm or 10mm joints without an adapter. The 2-inch length keeps things compact, so it works well on smaller rigs where a longer bowl would look awkward or get in the way of your face when you're taking a hit.

The frosted joint is standard ground glass, so it should seat cleanly on any properly made 18mm female connection. If your piece has a worn or loose joint from years of use, you might need to wrap it with some tape for a snug fit, but that's a piece issue, not a bowl issue. Most setups will work right out of the box.

Care and cleaning

Let the bowl cool completely after use, then soak it in isopropyl alcohol and rinse with warm water. The frosted joint can get sticky with resin buildup over time, so wipe it down regularly to maintain a good seal. Dry thoroughly before your next session.

FAQ

Will this fit my 18mm bong?

Yes, as long as your bong has an 18mm female joint. The frosted male joint on this bowl is made to fit standard 18mm connections. If your piece uses a 14mm or 10mm joint, you'll need a reducer adapter to make it work.

What colors are available?

The bowl comes with color linework accents in multiple options, but availability changes based on current stock. Check the product page or reach out to confirm what's available when you're ready to order.

How deep is the bowl?

At 2 inches total length, expect a shallow to medium pack size. This isn't a party bowl meant for passing around a group — it's more of a personal or small session setup. You'll get a few good hits per pack.

Does the fume glass actually change color?

Yes, and that's part of the appeal. Fume glass shifts in tone as resin builds up behind the glass surface over time. The color accents from the linework stay consistent, but the fumed base develops a richer, deeper hue with regular use. Some people specifically seek out fumed pieces because they like watching them evolve.

Is the frosted joint better than a clear joint?

Frosted (ground glass) joints create a tighter seal and grip better than smooth clear glass. They're standard on quality bowls and downstems because they reduce wobble and prevent air leaks during your hit. The tradeoff is that resin can build up in the textured surface, so clean it regularly to keep things sealing properly.

Can I use this on a bubbler?

Yes, if your bubbler has an 18mm female joint. Fair warning though — many bubblers use 14mm joints, especially smaller ones. Double-check your joint size before ordering to avoid the disappointment of a bowl that won't fit.

How do I clean resin buildup from the fume glass?

Soak in isopropyl alcohol (90% or higher works fastest) for 15-30 minutes, then rinse with warm water. For stubborn spots, use a pipe cleaner or cotton swab to scrub out the residue. Always let the bowl cool completely before cleaning — dropping a hot glass piece into liquid is a quick way to crack it from thermal shock.
