Glass (ὕαλος (also 'rock crystal'), vitrum). The art of producing a vitreous surface on stone, powdered quartz (faience), or clay was known in pre-dynastic Egypt and passed to Crete during the second millennium bce. Glazed objects are common on Greek sites of the Archaic period, some of them Egyptian imports, others probably made locally. In Hellenistic and Roman times Egypt and Asia Minor were centres of fabrication of glazed wares, which often imitated bronze.Objects composed entirely of glass paste begin to appear in Egypt about 1500 bce, when two allied processes seem to have been in use: modelling molten glass about a core of sand, and pressing it into an open mould. The chief Mycenaean glass is dark blue imitating lapis lazuli, used for beads, inlays, and architectural ornaments. In the 6th cent. small vases made by the sand-core process became known in Greece; they have opaque blue, brown, or white bodies and a marbled effect was produced on their surface by means of a comb or spike. In the Hellenistic period mould-made bowls come into fashion; these were produced mainly in Egypt. Here the tradition of opaque polychrome glass was continued into Roman times with millefiori bowls, in which marbled and other polychrome patterns were formed by fusing glass canes of various colours and pressing them into moulds.Less
