These are faience beads.
They are from Dendara. The faience makers of ancient Egypt produced innumerable beads. They were cheaper and easier to produce than stone beads. Many faience tube beads, like these, were used for the dead. Bead networks decorated mummies, for example. The small double beads in this pile made the threading of a bead network easier. There is a bead network in the case on mummification. These are faience beads. They are made from faience. They are between 2,000 and 2,350 years old, dating to the Ptolemaic Period (332-30 BCE).
