I share your concern, Maggiemaybe. In fact my first thought was for Mark Antony's words:-
........."Dost thou lie so low?
Are all thy conquests, glories, triumphs, spoils,
Shrunk to this little measure?"
Without any relevant experience or, I hasten to add, research. a beaker does seem inadequate. A glass receptacle would of course be too risky; something heavy and solid in silver or pewter perhaps? The cow creamer that features so prominently in one of the Bertie Wooster stories, some kind of a sporting trophy?
