These are cute little medium dark green powder glass beads from Ghana, Africa. The title "powder glass" is due to the process by which they are made.
They start as
recycled glass which is pulverized into a fine powder. This powder is
sifted into little molds then put into an earthen kiln to fuse the
powder into spheres. Each is carefully removed and a hole is pierced
with a pick by hand. This process gives them their distinctive matte
variations in size and shape. They add a sophisticated, ethnic, chunky
quality to your beadwork. They have holes large enough to permit
thicker cord and hemp. These measure about 9mm in diameter, but there is some variation from bead to bead as they are hand made. They are 20 cents per bead.
