A terp pearl, also known as a dab pearl or dab terpene ball, is a small spherical or bead-like accessory used in conjunction with a dab rig or dabbing setup. Dabbing is a method of consuming concentrates, such as wax, shatter, or oil, by vaporizing them at high temperatures.
Terp pearls are typically made from heat-resistant materials such as quartz, ceramic, or ruby. They are placed inside the banger or nail of a dab rig before heating. When the concentrate is applied to the heated surface, the terp pearl spins and moves around, helping to distribute the concentrate and enhance the vaporization process.
