Terp pearls are typically made of heat-resistant materials like quartz, glass, or ceramic. They are placed inside a heated dab nail or banger, which is part of a dab rig or a similar device. The purpose of terp pearls is to enhance the vaporization and flavor experience of the concentrate.
When the dab nail is heated to the desired temperature, the concentrate is applied to the nail surface. The terp pearl is then dropped into the nail, where it heats up alongside the concentrate. As the user inhales through the rig, the terp pearl creates turbulence and helps distribute the concentrate more evenly across the heated surface. This process can lead to more efficient vaporization and improved flavor.
