11" Double Matrix Perc Bong with 80mm Wide Body | Croia Glass

Built around a wide 80mm cylindrical body, the Croia Glass 11" Double Matrix Perc Bong features two stacked water chambers, each fitted with a large matrix percolator. The clear glass construction puts both filtration stages on display, while the bent neck and black glass accents give the piece a clean scientific look.

At 11 inches tall, this double chamber water pipe combines a substantial body with a relatively compact overall height. Its two-stage diffusion system is designed to break up smoke through successive water chambers, making it a distinctive option for anyone who prefers detailed percolator construction.

Key Features

• 80mm Wide Body: Large cylindrical chamber with a substantial glass profile.
• Double Matrix Percolators: Two oversized grid-style percs arranged in separate chambers.
• Dual Chamber Construction: Stacked upper and lower water filtration sections.
• 11-Inch Height: Compact vertical profile relative to its wide body.
• Bent Neck Mouthpiece: Angled design with a black glass rim.
• Clear Borosilicate Glass: Transparent construction with black accent details.
• Side-Mounted Joint: External glass inlet with an included bowl.

80mm Wide-Body Scientific Design

The defining feature of this bong is its 80mm-wide cylindrical body. The broad chamber provides space for two large matrix percolators without requiring an unusually tall glass tube.

Compared with a narrow straight tube, the wider body gives the internal filtration system more room and creates a substantial appearance. The transparent walls also make the two percolators easy to inspect.

The result is a scientific water pipe that emphasizes chamber size and internal glasswork rather than exterior decoration.

Double Matrix Perc Filtration

Two large matrix percolators sit inside the stacked chambers. Each features a cylindrical grid-style structure with multiple openings for smoke diffusion.

The lower matrix perc provides the first stage of water filtration. Smoke then moves into the upper chamber, where the second matrix perc provides another stage of diffusion before the smoke travels toward the mouthpiece.

This double matrix perc arrangement creates a more involved filtration path than a single-perc bong. The actual draw resistance and bubble formation depend on the internal openings and water levels.

Two Separate Water Chambers

A horizontal glass partition divides the body into upper and lower filtration chambers. Each section houses its own matrix percolator.

The stacked layout allows the two percs to operate in sequence rather than placing both diffusion structures in one shared reservoir.

The clear exterior makes it easy to see the water levels in both sections. Correct filling is important for maintaining airflow and limiting splashback.

Side-Mounted Inlet and Glass Bowl

The external glass inlet connects to the lower chamber through a curved side tube. This arrangement keeps the bowl separate from the main cylindrical body while directing smoke toward the first filtration stage.

A removable glass bowl is included with the water pipe. The side-mounted connection also gives the piece its recognizable scientific glass silhouette.

Bent Neck with Black Glass Accents

Above the upper chamber, the glass transitions into a bent neck with a rounded mouthpiece. The angled shape allows a more natural approach when using the bong on a table.

Black glass details appear at the mouthpiece and on the internal percolator tops. These accents contrast with the clear body without obscuring the filtration system.

The Croia Glass logo is positioned on the upper neck.

Clear Borosilicate Glass Construction

This water pipe is made from borosilicate glass, a material commonly used for scientific-style smoking accessories because of its thermal resistance.

The wide cylindrical chambers, stacked matrix percs, and curved inlet tube give the design a detailed appearance without unnecessary exterior ornamentation.

Its clear finish also makes residue and water levels easier to see during routine maintenance.

How to Fill and Clean

Add water gradually to the lower chamber, then fill the upper chamber to cover the working openings of its matrix perc. Test the airflow before use and adjust each water level as needed.

Avoid overfilling. Excess water can increase draw resistance and cause splashback.

To clean, remove the bowl and empty both chambers. Use isopropyl alcohol and a suitable glass cleaning method to loosen residue. Rinse thoroughly and allow the piece to dry before use.

The matrix grids contain many small openings, so regular cleaning helps prevent buildup inside the percs.
