Hmm I might've been overambitious. Searching "glass water bottle with measurements" gets a few Amazon results but so many of them have "motivational" time labels but no ml markings...
There are quite a few listings for chemistry reagent type containers, too, which could maybe work?
The best thing I've found is this from Dunelm might be what you're after?
It has "1.4L" embossed into the glass :)! it's just hard to see in the photos
