OK, so, when I said I couldn't DEFINITIVELY identify these I referring to the question who made and when.... the answer that was given I could have given off cuff but I didn't want to be generic I still don't have definitive info but ... I'd accept that yes first one is probably a game mib, second one is certainly translucent so it sort of qualifies as a "cleary" and Cleary was a marble made first by Akro Agate and it needs to be examined closely for certain traits. But clear single color and no color were so mass produced and they were made for so many toys and even sling shots. Also they were made for industrys like canned spray paint cans or Codd stopper bottles, kids would open both for the marbles inside. The clear / colorless marbles were used in stop signs and R/R crossing signs to give the sign a bright flash in the night when light hit them. Colored clear(translucent or transparent) marbles were also used in decorating and aquariums. They cannot be precisely identified to an age nor manufacturer.I can't definitively identify these. Maybe with more individual close ups it could help.
I'm familiar with fluorescent glass, it's caused by uranium oxide being present in the glass batch which dates it prior to 1940's I believe. That is the value....it helps date the glass and suggests that the glass item is old not foreign made recent....But! It's not fail safe bc some foreign and even US glass artisans are getting old cullet from old factories and dump sites..... so either dig it yourself or purchase from reputable knowledgeable ppl. Phosphorescence... is another dealie... and I'm not so familiar ..but, I'm of the understanding that that is new 1999 and later.Does fluorescent and phosphorescent qualities add value to a marble?
