The glassblowing technique

none

It is believed that this ancient method of making glass pieces was invented in the 1st century BC and, basically, it has not changed until since then: it involves melting glass paste at more than a thousand degrees, using a hollow reed to blow the interior and give shape to the handmade object. And, above all, it entails speed and skill in the hands of the masters. In 2023, it has been added to UNESCO's Representative List of Intangible Cultural Heritage.

This type of creative production, which requires many years to master, is strongly linked to Spanish culture: it has been used for three centuries, for example, in the Royal Crystal Factory of La Granja (Segovia), where it is also taught to apprentices. More individually, nearly a hundred and a half craftsmen help to keep the technique alive.In simple terms, the work method involves: the raw material (molten glass) is melted in a furnace at a temperature of more than a thousand degrees. When it reaches the soft consistency of incandescent paste, the master inserts the long metal blowpipe (empty in its centre), takes a piece of the paste, takes it out of the furnace and blows for the first time to create a bubble in the material, i.e. the hollow part of the glass, vase or piece you plan to make. The craftsman shapes his creation while keeping the bubble alive and uniform, inflating the glass and constantly moving the pipe on its own axis. New pieces of hot glass are added to the work to add handles, cup feet...

To finish, the object goes through a slow cooling called annealing, which happens in the lehr (special furnace). The final step is to add the final decoration to the piece. And that's how this ancient tradition remains alive today.
