It is an interesting mix of beads.
The small blue ones look like recycled glass beads from Krobo, Ghana. They are probably not very old.
The other bigger beads look like a mix between Venetian glass trade beads, probably made between 1880 and 1930 and powderglass beads, again from Ghana. The ones with a rough surface are the powder glass beads. I am not very good at dating powder glass beads, but I think these are no older than 20 or thirty years.

Other who can add/correct?

I don't think the blue transparent ones are recycled krobo beads. Maybe Chinese (lampion?) beads from an American store? The other Ghana beads from the 1960-70ties look more Ashanti beads, neighbours of the Krobo.

Here are some recycled glass beads I made, at a workshop by a Krobo beadmaker Florence Asare. To me, the small blue beads on the strand look quite similar. They were made with one piece of glass, heated, and then pierced. So no with powdered glass.
However, they are fairly plain beads, so could be very different in origin too.

Floor, notice the two beads stuck together, and the tail on one of the beads, typical of casually-wound or furnace glass beads. My vote would be India, as they have exported tons of such beads in the past 30 years.

Yep, both of you are right. Not recycled glass, but wound in some way.

if Indian they would have a black hole deposit, i feel they are either chinese (which are often called "jug beads" -found on antique bead curtains, etc ) or german.

The black comes from sticking the mandrel into the flame to get it sooty, the original "quick and definitely dirty" method for bead release?

I made a cropping of the most convincing beads.
The bubbles are also a clue for me.
