The pink satin glass beads are drawn and faceted tubes of glass with what look like silky fibres but may be actually drawn/stretched bubbles within the glass and the pink may be the result of a later process of soaking in a coloured dye that penetrates the tiny apertures by capillary attraction.... probably Czech? Others may have a different idea...iíve seen them in a pale blue and pale green as well-
The coloured ones dont appear Krobo to me but some glass and some perhaps plastic?
I agree with Stefany regarding the Atlas glass beads.
The multi-colored glass beads cannot be Krobo, since the beads are largely molded (Czech/Central European), and possibly wound. Krobos do not make molded beads, apart from their powder glass beads. And they do not make wound beads. So these would be imported into Africa (if they come from an African context).
if you search online for images of "atlas glass beads" there are any number of beads that are not correctly identified, including others drawn, faceted or lustred -so its good to be clear about this type and possible misidentification.
there is also a similar in appearance satin effect glass which is worked in a molten form with swirls, not tinted by dye, which i have heard described to me as "Atlas" by someone who had worked glass in the 1970s in Czechoslovakia when he was a prisoner of conscience, doing forced labour.
i found some yellowy ones with a similar faceted shape to yours at the link below:
Excellent! I had never heard of atlas glass before, every day is a school day! As for the multicoloured strand I had a quick look at them with my black light torch and 8 of them glow, which I guess would put these in Bohemia right?
Bohemia became the western Provence of Czechoslovakia in 1918. Your beads might be from this time or a bit earlieróbut they are probably mostly from the 1920s and later. I would call them "Czech glass." JDA.
