GRAV Quartz Hourglass Banger Set – 10mm 90°

This set includes the GRAV Quartz Hourglass Banger with a 10mm 90-degree male joint, one 20mm quartz marble, and two 6mm terp pearls. The marble is used as a directional carb cap to seal the banger and guide airflow, while the terp pearls sit inside the bucket and spin during inhalation to distribute heat evenly and increase concentrate surface area contact.

The hourglass shape features an inward curvature at the midpoint of the bucket that creates a narrowing between the upper and lower chambers. This geometry, combined with two laser-cut directional air intakes, generates a spinning vortex effect that keeps terp pearls in constant motion. The design is particularly well suited for cold start dabs and works to maximize concentrate coverage across the heated quartz surface for more efficient vaporization.

This banger features a 10mm male joint at a 90-degree angle, designed to fit any dab rig or water pipe with a 10mm female 90-degree joint. Always verify the joint size and angle on your rig before purchasing. The 10mm joint size is commonly found on compact and mini dab rigs, making this set a natural pairing for smaller setups where a lightweight, efficient banger is preferred.

Place the two included 6mm terp pearls inside the banger bucket before or after heating, depending on whether you prefer a cold start or traditional torch-and-wait method. Once your concentrate is loaded and the 20mm marble is placed over the opening, inhale steadily to create airflow that spins the pearls. The laser-cut directional air intakes in the hourglass banger are specifically designed to amplify this spinning motion for more efficient vaporization.

For most concentrates, heating the GRAV Hourglass Banger to between 450 and 600 degrees Fahrenheit and then allowing a 30 to 60 second cool-down period before dabbing delivers flavorful, low-temperature results. The thick gathered flat base and fully fused quartz construction retain heat well, so shorter heat times and longer cool-down periods generally produce the cleanest flavor. Using a digital thermometer or infrared temperature gun helps dial in the ideal temperature for your preferred concentrate type.

After each use, swab out the bucket with a cotton swab moistened with isopropyl alcohol while the banger is still slightly warm. The hourglass geometry can trap residue at the inward curvature, so take care to clean that area thoroughly with a thin-tipped swab. For heavier buildup, soak the banger and pearls in isopropyl alcohol for 30 to 60 minutes, rinse well with warm water, and allow to fully air dry before the next session.
