A Rare Ancient Near East Core Formed Glass Amphoriskos, ca. 6th - 5th Century BCE. Core forming is the earliest form of glass making techniques. Glass is shaped around the body of a core and removed, then wound colored trails and handles and rim added last. Cobalt blue with conical body and rounded shoulders. Cylindrical neck with opaque yellow and turquoise threads that spirals around body. On custom stand. Ex: Gershon Bineth collection, Israel. Glass is 3" high x 1 3/4" diameter, on custom stand height is 3 3/4". In very good condition. According to the British Museum, Core-forming involved coating molten glass around a core of dung and clay mixed with a little water and adhered to a rod. Decoration was added by trailing soft glass of a different color around the body of the vessel and combing it into patterns with a pointed instrument. After re-heating, the shoulder, neck and rim were formed and any handles added before placing the finished vessel in an annealing furnace to cool slowly. Finally the rod and core were removed. Beads and the like were formed by a similar process: a rod coated with release material (previously fired clay, pulverized and mixed with a little water) was used instead of a core.
