Siru was born in Venice from Rudy Marinotto's intuition: to combine the art of
Murano glass with metal cages, creating a striking dialogue between the fluidity of blown glass and the geometric structures it fills. This is how Siru's "luminous imperfection" came to life, a formula that makes each creation absolutely unique. Siru is the Venetian tailoring of light.
Siru blown glass lamps: the production process
Sand and minerals are the raw materials: glass is obtained by fusing these essences, while steel is worked to shape the metal structure. Siru products are created from a stainless steel frame into which the glass is blown, using ancient Murano artisanal techniques.
The glass production cycle is divided into four fundamental phases: preparation of the mixture, melting, refining, and cooling to operating temperature. Only then can the actual processing begin. To achieve exclusive finishes, the glass is first placed in a mold that imprints its initial shapes; it is then blown into a steel cage—a distinctive element of the brand's creations—which replaces the traditional mold, allowing the glass to expand and shape until it reaches the desired form.
After the glass blowing process is complete, the product is subjected to a tempering process, which allows for controlled cooling, preventing breakage and giving the glass greater strength. Only once the glass has reached the correct thermal stability can the next steps be carried out: cutting, grinding, and drilling, according to the project specifications.
Siru's strength lies in its ability to preserve the tradition of Venetian artistic craftsmanship while integrating it with cutting-edge production. Today, the Siru production line is equipped with welding robots, three-dimensional bending machines, and technologically advanced polishing baths, ensuring an exclusive, refined, and reliable product.
