Thank you for the idea. The markings go from 1-7, which is below the neck. I filled the bottle to where the neck meets the curve and poured it out and it measured about 3/4 cup.
Thank you for verifying that it is old.
Thanks. I don't know glass color names but the photos are pretty accurate. The color is more saturated at the bottom. I wanted to at least confirm that it is old and not a recent decorative piece of glass. The graduations had me thinking it was older. I'll keep searching online with the new...
I am in the US and bought a bottle at a second hand shop and would like to find any information about it. I searched online and could not find one similar. It is blue / aqua, about 7 inches tall and the only marks I see are faint graduation marks on one side. Attached is a photo.
Thanks
