Featured Odd huge heavy glass beads (soda) - opinions?

I do love beads just don't know very much. In one of my volunteer projects I spent one day a week for several years sorting the tiniest objects from fine screened midden soil. It was fish scales, lead shot, and anything cultural. Favorite things to find were pins and beads. Here are a sample of beads from the project.

Ooh. I bet that was fun.

 

Loved every minute of it with my face against a magnifying glass picking through what often resembled kitty litter. It's all rather fiddly which suits my personality apparently. (Does make one wonder about me though)

I hope someone knows about your beads.
