A terp pearl, also known as a dab pearl or terp ball, is a small spherical or bead-like object used in conjunction with a dab rig or dabbing setup. It is typically made of a heat-retaining material like quartz, ceramic, or ruby.
Terp pearls are placed inside a heated quartz banger or dab nail, alongside the concentrate (such as wax or shatter), before the dabbing process. When the concentrate is heated, the terp pearl helps distribute the heat more evenly, allowing for better vaporization and enhanced flavor.
