hello Patricia......... regret no idea as to age - substantial wear might indicate if it was genuinely old, bearing in mind its utility design. I would suggest this is either a carafe or decanter of some sort - does the inside of the neck indicate wear from a stopper? Genuinely old glass is often (though not always) thicker and heavier than modern pieces, and the fact that yours is lightweight tends to support the idea that this one is not old.
Would also suggest that your glass is copying an C18 stopperless decanter...........it has what I believe to be an 'applied string-ring' (used to anchor the string which held the cork in place), although this ring seems a little low on the neck.
The substantial 'kick' was also typical of that period..........helping to both hide the snapped pontil scar, and (I think) providing extra strength during annealing. Seems also to assist with pushing the sediment into smaller area.
Sorry this is of little help with regard to identification, but suspect you aren't going to find a maker. Age might be determined by wear, seeds, and type of glass. Perhaps someone else will know of a factory that is known for copying these older pieces, and in this pale blue colour.
But it looks attractive
