Glass production evolved during the Roman Empire with the introduction of glassblowing, which allowed for a great variety of different shapes and styles to be constructed. The technique allowed for easier manipulation of the glass into more intricate designs allowing the vessels to have an assortment of functions. Glassblowing also allowed for a quicker paced production, the hot glass would be blown into a mould and then removed whilst still hot so that the glass maker could still work on it. Roman glass is formed from sand (quartz) which naturally contained alumina and lime. The lime acted as a stabiliser, so that the glass was not porous. Sodium Carbonate, in the form of natron, was also added to lower the melting point. The only surplus components then found are additional elements used to colour the glass. Different minerals were added to create a variety of colours; the green colouring seen in this piece would have been intensified by the addition of copper.
Ancient Roman Dimpled Green Glass Bowl
An exceptional ancient Roman bowl blown from translucent green glass. The vessel features a small hemispherical container, with straight walls which raise from a short tubular foot to render an elegantly slanted profile. A thin rim is folded outwards at the top, finishing this fine piece. Small and evenly spaced knobs feature on the surface, adding to the vessel’s overall texture and design. A vestigial knob pushes up from the bottom of the bowl to form a central internal knob.
Please note that the measurements provided below are inclusive of the stand. The bowl itself measures: W 14.9cm x H 7.4cm
Condition: Very fine condition. Sharp edges on the bottom of the bowl where the glass rod was cut in antiquity. Some weathering on the surface.
