A Roman glass unguentarium displaying a yellow core laced with white, brown and blue marbling. It features a long cylindrical neck leading to a piriform shaped body. The neck tapers outwards to an everted rim, folded over and slightly flattened. The base is flattened and slightly concave in the centre. Rough surface with some air bubbles and silvered iridescence. The piece was formed from a combination of casting and blowing and were produced in the period before the popularity of blowing began. Canes and rods of pre-formed coloured glass were arranged and fused together through re-heating. The glass was then manipulated to create unique ribbon-mosaic glass. The surface of such glasses tends to be rougher due to the nature of its creation. Measurements: H 9.3cm Provenance: Ex major S.M., London, Collection 1970-2010.
