Original Message:   If they have turned more reddish with age
If it's not an artifact of the photography, and the beads have turned more red with time, then that is one confirmation of phenolic resin.

If you have some household ammonia, wet a cotton swab with a tiny bit and rub a place that doesn't show. If the swab turns mustard yellow, that is also a good sign for phenolic resin.

I have been using "Bakelite" interchangeably with "phenolic resin" since many more people know this trade name and associate it with old plastic.
