Usually when a glass bead is heavier than expected, it is because the glass composition includes leadówhich can be used to make the material more substantial, reflective, or to alter color(s).
(In antiquity, in China, barium was added to glass compositions of the Warring States Periodóresulting in glasses that were heavier than others. Again, if I don't say this, I will probably hear about it.)
Your yellow beads are very curious. But I cannot say I recognize them.
