The blown glass technique is attributed to the Phoenicians or Babylonians in the 1st century BC, with the invention of the blowing cane. It requires physical strength for the glassmaker to hold the heavy mallet with one hand and print a rolling movement to the cane with the other. These two movements, essential for the shaping of the glass bubble, are acquired by the craftsmen after a long apprenticeship. Lalique crystal factory is known for hiring the best glassworkers to maintain its excellence standards.
