Pulsar Quartz Fat Bottom Banger – 90 D

A fat bottom banger refers to a banger with an extra-thick bottom disc, in this case 5mm, compared to a standard 2mm or 3mm bottom. The additional quartz mass at the base absorbs and stores more heat when torched, allowing the banger to remain at vaporization temperature for a longer period. This is especially beneficial for low-temperature dabbing and cold-start techniques.

This banger comes in a wide range of sizes including 10mm, 14mm, and 19mm joint sizes, with both male and female configurations available, all at a 90-degree joint angle. This makes it compatible with the vast majority of dab rigs on the market. Always check the joint size and gender of your rig before purchasing to ensure the correct fit.

Yes, the 5mm thick bottom on this banger is well-suited for cold-start or reverse dabbing. In a cold-start session, concentrate is placed in the unheated bucket and the torch is applied after loading. The thick bottom heats evenly from a cold state and reaches vaporization temperature without overheating the concentrate, which helps preserve terpene flavor.

A groundless joint means the joint stem does not have a frosted ground glass surface. This design provides a direct airflow path with no textured surface to create resistance, and it is slightly easier to clean than a ground joint. Groundless joints still form a secure connection with matching female joints on a rig.

The flat top opening on this banger is compatible with a wide variety of carb cap styles including flat caps, bubble caps, ball caps, and directional caps. Any carb cap with a diameter of 25mm or larger will cover the opening and create effective airflow restriction for low-temperature dabbing.

Ideally, the inside of the bucket should be swabbed after every dab session while still warm to prevent concentrate from carbonizing on the quartz. Carbonized residue that is left to harden requires longer alcohol soaks to dissolve and can permanently stain the quartz if left for extended periods. Consistent warm swabbing preserves both flavor and the clarity of the quartz.
