A large Ancient Roman blown glass flask displaying a natural pale-green colour. The vessel stands on a slightly concave base, from which its broad globular body raises and tapers into a long cylindrical neck. A large mouth opens at the top, marked by a slightly outsplayed vertical rim with a folded, hollow horizontal flange below. Bright iridescence partly covers the flask, travelling from the mouth down to the neck and side of the body.
Date: Circa 4th century AD
