Topic: am I getting warm on this research?

friends:
OK, i bought a book entitled ANTIQUE DRINKING GLASSES: A PICTORIAL HISTORY OF GLASS DRINKING VESSELS, by Albert Hartshorne, copyright 1967, former (original) title was OLD ENGLISH GLASSES.  It is a massive book, 490 pages long.  All illustrations are drawings and the book covers drinking vessels from from Roman Times to circa 1800 or a bit more, primarily English drinking vessels. (I bought the book specifically hoping that there might be something in there about his glass.)  I looked all through the book, and there was only a couple pieces in the entire book with a square foot and they were referred to as GROG GLASSES. 
according to text: "Grog was a rum-based drink, described as a solitary, sullen and dismal drink, as distinguished from gregarious punch in the social bowl, but almost the same thing, only with fewer ingredients.  the text referring to figure 325: Many very pretty square-footed, cut and engraved grog glasses, some quite small, were produced from the early years of the last quarter of the century (referring to 1775-1800), delicately treated with festoons, beadings, flutes, and flowers (fig. 325) and often bearing the owner's initials on a rectangular or oval panel, as in the example in Mr. J. Hawkin's collection (fig. 326).  These somewhat gave way before the end of the century to moulded and fluted goblets, large and small, of some merit, engraved with ribbons and festoons after the Adams fashion, and often oil-gilded........all of these passed into the nineteenth century where we take leave of them."   That was the extent of all reference to a square-footed glass in the book.
 
so, my question: am I on the right track with the original purpose of this glass?  illustration from the book, followed by a picture of my glass.  If grog is a rum-based drink, this amber color would serve the purpose of masking the color of this 'solitary, sullen and dismal drink'.  As this piece is uranium glass, it is a bit late time frame (with uranium glass not being used until about 1835-1840).  The glass is cut, with a very high bell tone.  It is small (square base 2 1/8", height 3 3/8", and top diameter: 2 3/4").  center photo is indoor room light, right photo is outdoors with sun's UV, left photo is Blacklight.
the only damage is one badly chipped corner of the foot (shown in all photos as back right corner).  polished pontil, shows plenty of wear on the underside of the square foot.

Hi Dave, i dont know about the original purpose of your glass, but Grog was a naval drink, a mixture of Rum and Water, and could up to 1/2 a pint.

If you read down, the term grog appears to have come from the West Indies and is probably of African derivation. It first appears in English in 1718 by Daniel Defoe in reference to what appears to be rum itself. Maybe this is a rum glass based on a much older design
