I had worked this out back in 98, using real glass vials. Saying a glass vial weighs 1/10 of a pound is ludicrous, modern glass blowing makes them heavier than that and the D&D pseudo medieval world wouldn't have been better than modern times. Ok, enough rant.
In real life, a 1 oz (8 dram) vial is 3.5" by 1.25" diam. and weighs 4 oz or 1/4 lb, with roughly a 3 oz. dry weight. Cost was 1 gold as of a 1984 Dragon article (Living in a Material World) and in 3.5 players guide.
Now, further Canon is from the first DMG and is about the price of Holy water vials, which have to be special or the holy water will loose its power ...within specially blessed/cursed vials of crystal - either rock or special leaded glass. Each empty vial is worth 2-5 gold pieces. I kept this as a separate price, and the rules therein on the manufacture of holy/unholy water, to eliminate the mass production of these substances. I also had 4 oz vials which were 4.5 inches tall and 1.75 in dia 8in circumference, and weigh 6 oz empty.
Ooopps, left out the one discrepancy, they made up a size and lowered the volume capacity of what I had come across, but adds info as well. The Vial has a AC 13 (+8 size, -5 dex, 1 hp, hardness 1, and a break DC of 12-DMG pg 229). This is for Ceramic or glass, Metal would also be AC 13, but have 18 hp and hardness would be 9 (-1 less than iron or steel for brass or bronze, -3 for any softer metal like electrum, -4 for gold or silver, -5 for platinum, +2 for Titanium) Vials are listed as holding ½ oz or .16 lb
Getting this technical was due to having Physicists, Chemists and IT geeks as players. Don't get me started on flasks, or the fact that pot makers lost money turning iron into kettles based on book prices.
