Glass Jars.

I got these three at the Unique on Sheridan last week:

(That’s not a very good picture, sorry. I have trouble focusing on clear glass.) I am wondering how old they are. My friend Roxana, who is a pro (check out her new blog, by the way) said that the bubbles in the glass and lack of the seam are clues, but don’t really definitively age the glass, that you have to look at the bottom and look for the bubble.

So I see a bubble, but I don’t know if it’s the right bubble. All of the jars have rings on the bottom (I don’t know if you can see them in this photo or not) but this jar is the only one with the bubble in the bottom. The glass stoppers are all chipped to varying degrees:

And those are all the clues I have. Anyone have any ideas? If they’re not old, what the heck are (or were) they for?

Glass jars…yet another thing I can’t help but buy.

Ord-Red They look like lab or apothecary bottles. These guys might actually be molded based on the thin ridges on the stoppers. Though they appear to have the ground away dimple of where the the blow pipe that forms the glass was attached (they’re called pontil marks or scars). It’s hard to tell from the photo, but could be.

If you really love glass (I do) and want to get your nerd on (as I frequently do), you can check out this link. It helped me figure out a lot about identifying and dating glass bottles.

Lara Jo Okay, everyone needs to follow the link Roxana posted. It has EVERYTHING you could ever possibly want to know about glass bottles and then some.
