Take a look at the interactive glass timeline on the CMoG website: http://www.cmog.org/visit/schools-groups-and-scouts/school-tours/resources/timeline-glass-history
It includes a timeline of world events for comparison.
Some others found online (I haven't "fact checked" them):
About Glass (UK)
Metropolitan Museum of Art:
- ancient glass: http://www.metmuseum.org/toah/hd/rgls/hd_rgls.htm
- art nouveau: http://www.metmuseum.org/toah/hd/artn/hd_artn.htm
(explore other categories for glass too)
Let me know if you need additional information.
