GRAV Quartz Hourglass Banger Set – 10mm 45°

This set includes the GRAV Quartz Hourglass Banger with a 10mm 45-degree male joint, one 20mm quartz marble, and two 6mm quartz terp pearls. The marble serves as a directional cap to seal the banger and direct airflow through the laser-cut intakes, while the two terp pearls sit inside the hourglass bucket and spin during inhalation to distribute heat and concentrate evenly across the quartz surface.

This banger is designed for compact and mini dab rigs with a 10mm female 45-degree joint. Rigs with angled downstems commonly use the 45-degree configuration, and the 10mm size is standard on smaller rigs where a lightweight banger is preferred. Confirm the joint size and downstem angle on your rig before purchasing, as a mismatch in angle will result in the bucket sitting at an incorrect tilt that interferes with concentrate loading and vapor efficiency.

The inward curvature of the hourglass narrows the center of the bucket, creating a constriction that accelerates airflow from the upper chamber into the lower bucket area during inhalation. Combined with two laser-cut directional air intakes angled to promote rotation, this geometry generates a spinning vortex that keeps the terp pearls orbiting continuously. The moving pearls redistribute concentrate and heat across the entire lower bucket surface, preventing pooling and ensuring more complete vaporization compared to a stationary flat-top banger setup.

Yes, the GRAV Hourglass Banger is designed with cold start dabbing in mind. Load concentrate into the cold bucket with the terp pearls already inside, place the 20mm marble over the top, and apply torch heat from below the bucket. As the quartz heats up, the concentrate will begin vaporizing from the inside outward, preserving lower-temperature terpenes for a more flavorful result. The thick gathered flat base stores heat evenly during the cold start process, providing a consistent temperature rise.

The included 20mm quartz marble fits the top opening of the GRAV Hourglass Banger and is the recommended cap for this set. A directional bubble cap in the 20mm to 25mm range that seats comfortably over the banger opening can also be used. A proper seal between the cap and the banger top is essential to create the airflow restriction that drives the spinning motion of the terp pearls through the directional intakes.

Clean the hourglass banger after each session by swabbing the interior with isopropyl alcohol while slightly warm. The narrowing at the hourglass mid-section can collect residue, so use a thin-tipped swab to reach all internal surfaces. Clean the terp pearls and marble by soaking them in isopropyl alcohol for 15 to 30 minutes, then rinsing with warm water. Regular cleaning after each session prevents chazzing, which is heat-induced discoloration that degrades quartz performance over time.
