A technique invented in Syria
0
0
The technique of glassblowing is attributed to the Syrians around 100 BC, thanks to the invention of the blowing rod. At Lalique, the glassblower, equipped with a long hollow metal cane, takes the molten crystal from inside the furnace. In order for the viscous material to adhere to the rod, it must reach a temperature of approximately 2,190°F (1,200°C). Depending on the volume of the piece to be made, the blower has to collect up to 44 lb (20 kg) of molten mass at the end of his rod. Blowing glass or crystal requires a great deal of lung capacity, as the blow must be regular and continuous until the desired shape is obtained.
