Studio Glass/Cast Glass. Vessel. Cobalt Blue Agate Geode. Jarman, Angela (British, b. 1971). Cobalt blue lead crystal vessel, produced by lost wax casting, with mixed blue murrini cover. The vessel has a near-spherical shape with a wide mouth. The outside is polished; the interior is multifaceted with a rough surface; the walls are thick with an indented rim around the mouth to hold the insert; the underside is flat, circular and polished. The insert is a smooth, flat disc, with an off-centre circular hole, coloured with irregular, roughly concentric bands of fused opaque grey, blue, turquoise, pink and red glass. Between the bands and in the centre are wider areas of translucent cobalt blue glass, in which cell-like forms can be seen. Lead crystal, cast and polished, with mixed blue murrini insert. Height, whole, 12.5 cm, diameter, 20 cm, 2017. Production Note: Murrini, glass mosaic that resembles agate stone, is characterised by fusing together differently coloured glass into concentric streaks, typically of purple and white. The process was known in Roman times and rediscovered by Venetian glass-makers in the 16th and 19th centuries. Acquisition Credit: Given by Nicholas and Judith Goodison through The Art Fund.
