| | Bead - Wikipedia, the free encyclopedia |
 | | Glass, plastic, and stone are probably the most common materials, but beads are also made from bone, horn, ivory, metal, shell, pearl, coral, gemstones, polymer clay, metal clay, resin, synthetic minerals, wood, ceramic, fiber, paper, and the seeds of the Bead tree and other trees. |
 | | Seed bead machinery uses glass rods softened to a red heat, fed into a steel die stamp that forms the shape of the bead with a reciprocating needle that forms the hole. |
 | | Seed beads used by craftspersons should not be confused with Seed Beads™: laboratory-grown beads made of PTFE used to generate seeds of protein crystals. |
