old bottles, new collector

[AmIBlue]

I have a number of bottles that I have collected just because i love the colors. However I am interested in dating them I have both old bell jars and other bottles. The one i am interested in at the moment has IG Co L on the bottom and has either a flask lip or a brandy lip, not sure which one as im still learning how to id them.

Dating bottles that have no company becomes difficult. The lip is a blob top.
This web site has lots of information especially for bottle makers marks.

Welcome to the forum! Looks like Illinois Glass Company, I'm guessing 1880s based on the applied lip and the look of the base. I've never heard of flask lips and brandy lips before, I don't think that's typical bottle collecting terminology.

I was searching how to date bottles and thats what came up on a website for trying to date by narrowing the date by the lips. I did think it was an Illinois Glass company so thank you for confirming that for me.
