Hi everyone, I would like to ask the forum a few questions about how to know what time period a particular wedding cake bead is from.

For example I understand that older beads were made with gold foil applied to the outside of the bead where as mid century to modern beads adventurine glass is used instead. When did the adventurine glass take over from the gold leaf?

Are there any other tell tale signs to look out fo?r irregular bead shapes? Colour ways? Designs?

I’ve tried searching the forums but I couldn’t find any real specifics. If someone could point me in the right direction of an article perhaps I would be very grateful.
