only joking Nev. In fact I like them, but would suggest possibly not wine glasses in view of the short rather chunky stems ………… but nothing Georgian about them - uranium in glasses didn't start commercially until c. 1840.

Use wise, these might be for port possibly or toddy, but they have the appearance of a tavern glass maybe.
Let's see what others think as to use and date.
