Here is an example of what I was seeing in the 1990s, not so much since about 2005 or so, when things got a lot more colorful and sophisticated.

They look consistent with a batch that we bought about 15 years ago that had been in Duke University's collection. They all had been accessioned in 1983, tagged, so I'm guessing at least as old as 1970s for those.

I think I got a better pic and also included a penny for scale. I do think mine are a bit larger than the other strand shown. The strand is quite hefty.

...does the fact that cotton was used to string them up as opposed to raffia have any implications in regard to age or anything else? Was it a matter of just what is handy at the time? Sorry if this has been covered before.

My experience is that Krobo powder glass beads come in many sizes. I have some that are tiny rice sizes. I have some that are 10-12mm. I've had some that were huge, as big as golf balls.

...which is why I said I believed mine were a bit larger, larger not better or more definitively Krobo. Not a contest, was just making a comparison.

I am still interested in an answer to my question about how beads in strands are strung, that some are on raffia and some on cotton string and is that any indication of anything at all, or simply a random choice.

Ooooops, Proceed to my next Post. Sorry.

A heated, and repaired seven layer green.

...that this pendant is a Krobo pendant?

Chevron strand from left: Very cool square Seven layer, Yellow black and brick faux, pitiful green seven, extraordinary black seven, white black and brick faux, and Krobo heated, reconstituted green seven.

I really like the big black beads with the squiggle lines and the reworked piece of green chevron.
