Something that comes to mind when looking for quartz bangers, go hard or go home! Thermal bangers are becoming popular because they allow you to do big dabs at low temperatures which keeps the flavor on point. This is because of the way the two layers of glass insulate the 'oven' once the globe style carb cap is dropped into place. The diameter of the XXL thermal bangers is 50mm which means you can drop globs of concentrate and get the most amazing flavor ever without running out of heat and being left with a disappointing puddle at the bottom of the banger.
