This is a machine-made brown/amber glass bottle with a matching glas stopper, possibly used for storing medicine. The bottle was probably made in three pieces; there are mold seams running over the entire length of the bottle (body, neck and rim), although they are less visible on the neck, and around the base. The base is embossed with the markings "150" and "9445", which are most likely an indication of the content (150 ml?) and a number related to the mold, the production lot, or internal categorization by the manufacturer.
Using the Society for Historical Archaeology's online bottle dating guide, this one is definitely past 1940's, though I know too little still for a better estimate. (Maybe I'll revisit this as I learn more ^^)
I've worked as a bench chemist prior to acquiring my chemical engineering degree. Make sure you apply stopcock grease on the ground glass so the cap doesn't "freeze" to the ground glass inside the neck of the bottle. Cool bottle...brings back memories :)
Thanks for the love and for the tip! I also collect clear laboratory glass, and in one lot I bought there was a piece that had a broken stopcock stuck in it; I don't use these for anything other than decoration so I didn't mind too much, but I still wondered if there would be a way to get it out xD
