Ronan & Erwan Bouroullec worked on the precariousness of the equilibrium between hand-blown glass and an industrial supporting structure. There is only one un-fixed, sharp point of contact between the glass and a delicate aluminium stick that is supporting it. Ronan & Erwan Bouroullec wanted to work with the vulnerability of this voluminous glass object. What was also interesting to them was the mix of techniques used to make the three elements of the lamp: The base and the stick are industrially made in opposition to the hand blown glass which uses traditional methods of manufacture. The colour of the glass shade varies between dark grey to amber. The base of Lighthouse is marble.
