I was asked a similar question at a recent Rings & Things bead show.
A customer saw the tag "MUD BONE" on a strand of what I would call batik bone beads from East Africa. She wanted to know what "mud bone" means. I guessed it meant the bone was dyed with mud having certain minerals in it, like how iron can stain things orangish.
I just found a web page that discusses the name "mud-cloth beads", for the same sort of beads. They say it's a comparison to the look of (but not the process used in making) certain styles of fabric in Mali.
Anyone know more about these beads and names?
