Uranium-salt beads were most likely made between 1830 and 1915. The Czech names for the green and yellow varieties are "Anna green" and "Anna yellow." Uranium salts were used as a yellow colorant and, as a side effect, glass beads containing uranium salts fluoresce under ultraviolet light. They are considered safe because vitrification "traps" the uranium inside the glass. Testing suggests that you can wear uranium-salt glass beads for up to 40 years before the radiation exposure equals that of getting a single x-ray at the doctor's office.
We carry a full line of African beads, both old trade beads, and newer beads made or strung in Africa for the world-wide bead trade. Trade beads are old and/or used beads, and will show varying amounts of wear. Newly-made African beads are generally handmade in small communities. Style and availability vary.
Bicone "vaseline" glass beads. Vaseline beads got their name because many of the colors available have a "greasy," translucent appearance resembling petroleum jelly. 22-26" strands of 12-14mm green beads. These strands may or may not contain uranium-salt beads that fluoresce under ultraviolet light.
