It's broken but I'm thinking dose cup? I've never seen one before. Found in the same ole 1800's trash pit I've been digging in for months. Thank you in advance!!
These pulled out of a dumpster at a remodel of an old pharmacy. There also were a half dozen big heavy old porcelain mortar and pestles, absolutely beautiful and fairly rare pieces, all broken except the smasher things some of which survived I dont know if the smasher thing is the mortar or the pestle. I felt like smashing the dumbazz worker dudes in the head with the mortar or pestle thing they did not have a clue if they only knew what treasures those were they just threw them in the dumpster smashing them. In retrospect I cant believe how lucky I was to find these beakers unharmed. My big glass beaker is pontiled and well-used with patterned cross-hatched scratches from the glass stirrer. I also found a small clear glass graduated beaker like the op's, the size of the porcelain one, not pontiled but copper wheel engraved also. My buddy somehow got me to give it to him he was begging.
Thanks surf but I still cant remember which is the pestle nor the mortar I just dont get it there is no hope. I could google it but in a week I'd forget. I am certain that this malady has something to do with a horrible repressed memory of an incident I experienced in high school chemistry class. I hate chemistry.
