MRS. STEWART'S BLUING bottle

Yup, one more from 'guess where' just because it caught my eye... ;-)

This little old (-ish?) bottle includes that particular product name (something people used to use while doing laundry, I think?) twice around the base of its neck with a little pebbled line of pattern below that, then another similar at its base. About 6" tall and 2-1/2" across it actually appears to be made of clear glass (note pic 3 where 'ya can kinda see sideways thru its bottom) that otherwise now appears totally opaque even when held up to a light, presumably because of the substance it once held. (and indeed is likely about 1/4 still full of, there's some kinda bit of liquid still in there?) It no longer has a cap, just a little plastic bit stuck in its top which (thankfully?!!) is also apparently 'stopped up', as none of whatever that fluid in there has managed to leak out of it in the meanwhiles since I brought it home with me. ;-) :-)

Markings on its bottom will probably tell some of y'all at least where the bottle itself was made, the main one is an 'I' in an 'oval' which I'll guess (if I'm actually learning anything like that from all y'all anyways?) might be Indiana Glass...??

[edit#2: due to the courtesy and expertise of bottle-bud and iggy, indeed I got the bottle's maker wrong, it is Owens-Illinois instead, also maybe a good bit older than I would have first guessed...THANKS, FRIENDS for the corrections!!!!!! :-) :-) :-) ]
