<P> During the Late Bronze Age in Egypt ( e.g. , the Ahhotep `` Treasure '' ) and Western Asia ( e.g. Megiddo ) there was a rapid growth in glass - making technology . Archaeological finds from this period include colored glass ingots , vessels ( often colored and shaped in imitation of highly prized hardstone carvings in semi-precious stones ) and the ubiquitous beads . The alkali of Syrian and Egyptian glass was soda ash , sodium carbonate , which can be extracted from the ashes of many plants , notably halophile seashore plants : ( see saltwort ) . The earliest vessels were ' core - formed ' , produced by winding a ductile rope of glass round a shaped core of sand and clay over a metal rod , then fusing it with repeated reheatings . </P>
