Roman small glass cup or bowl

This bright green glass vessel is ambiguously listed at the museum (no tag), but it's either a small free-blown bowl or cup, possibly to hold sauces for dipping during a meal. It shows some iridescence due to age.

 

Roman, 1st century CE, from Pompeii or the general Vesuvian area.
