So I was interested to find that a Roman glass jug has just been sold on e-bay for just $9.90.
Incidentally, the ARLT has collections of such objects for loan. They are best picked up at Summer School or Refresher Day, to avoid the postage to you on the bulky protective housing, though you do have to send them back. See Resources for Classics.
Incidentally, today brought news of a Dudley Museum's award for presenting an exhibition in the Romans on a small budget (Dudley News):
At the Renaissance West Midlands Awards on Thursday April 3, The Red House Glass Cone in Wordsley won best exhibition for a small budget' for its Romans exhibition.It can be done.
