Sprinkler flask, glass, maker unknown, Roman, c. 3rd century CE
The flask has a bulbous body and a cylindrical neck. The neck is broken at the rim. It is crudely levelled off with a centrally pierced diaphragm across its base. It is pale green-yellow with some iridescence and ivory encrustations. The body is decorated with four vertical ribs pinched at the top and bottom, alternating with four fin-like projections. There is a ring of similar projections emerging from the base and acting as feet. It has no pontil mark.
