Tighter airflow - Having a tighter airflow means more restriction and less room temp air cooling down your quartz banger. Room temp air enters the quartz banger as you use your cap which causes your banger to cool down. A larger airflow means your banger will cool down quicker. Bubble caps made with tighter airflow allows for a longer, milkier hit.
Linework Glass - The colors represented in this carb cap were created by preparing various sticks of color rods evenly inside of a large glass tube which was orientated to have a hollow section the middle. This large chunk of glass was then sealed and attached to a vacuum pump. The artist must carefully heat the glass sticks together, fusing them while the vacuum pump removes excess air. This process is tricky to complete without trapping air bubbles in between the glass rods as well as expensive due to the large amount of solid color that is used to create the final linework tubing section.
Easy Handle - Easily spin this bubble cap on your banger without covering the airflow hole. The airflow hole is created on the side of the bubble cap so it won't accidentally be covered while spinning this cap.
