While in Tanzania, I had the priviledge to visit Shanga, which employs handicapped people, mostly deaf to create glass beads and jewelry. http://www.shanga.org/
Needless to say, I was on cloud 9 when I found out that was going to be our first stop on day one of our trip! Being deaf--I had cochlear implant surgery 5 years ago--which was nothing short of a miracle--and making glass beads myself the visit to Shanga was a big highlight for me. They make their glass beads out of wine bottles and their process is somewhat different from what I am used to. They melt the glass in a kiln, dip in a mandrel--no bead release--, pull out a blob of glass, shape it into a bead, then remove it immediately from the mandrel and cool it in a fiber blanket. I don't think I got a good picture, but I'll look. I thought that I was going to get to try to make a bead while there, but, do to the language barrier, I missed my chance!
