This recipe of 658 B.C. is still valid after 2,500 years. By mixing quartz sand, potash and lime, glass is obtained, a natural raw material, waterproof, malleable and resistant.
The history of glass then followed its course. In about 100 BC, a glasswork on the Syrian coast was the scene of a technical revolution: a glassmaker whose name is unknown invented the blowpipe. The latter is a tube between 1.20 and 1.60 meters long with a mouthpiece on one end; the other end is used by the glass blower to draw, retain, rotate, marble and give homogeneity to the glowing glass bubble, by blowing air into it. Thanks to the blowpipe, the master glassmakers could now also produce glass objects of reduced thickness and with different shapes. A hundred years later, at the Romans, were already used luxurious glass glasses embellished with complex decorations.
