The flywheels and tensioners of home textile production.
A spindle whorl is a small centrally-pierced flywheel — stone, ceramic, bone, or lead — typically 2–5 cm across, dished, domed, or biconical, sometimes decorated with ring-and-dot or incised lines. Every household spun thread, so whorls span prehistory to the post-medieval era in quantity.
Loom weights are their bigger cousins: fired clay or chalk rings, triangles (an Iron Age favourite), and pyramids that tensioned warp threads on upright looms. Distinguish whorls from beads (whorl holes are proportionally larger and wear differently) and from pierced net sinkers (context and material help).
Weigh them — whorl weight determined thread fineness, and archaeologists reconstruct textiles from whorl statistics. Record diameter, height, hole diameter, material, and decoration; a decorated lead whorl may also be datable by its ornament style.
