From concrete to bronze, Spira lamp.

​

From the ancient Greek - spira - the helix is, in geometry, a curve in space in three dimensions wrapped around an imaginary cylinder, at a constant angle concerning a fixed central axis. This geometric shape is present in nature as well as in many man-made objects and structures. The result is an economy of simple and elegant lines but with a touch of structural complexity. My design follows this shape with a double helix where both curves are then connected to the central vertical axis at their ends. The volume created, first filled with concrete - then cast in bronze, forms the central body of my lamp, which rises on a cylindrical base. Despite the materials' robustness, this design aims to create lightness and contrast. The concrete lamps are composed with recycled aggregates inside the mix to have a more sustainable result, also thanks to some kind advises shared by a Finnish company Betoni.

The third version has been produced by sand 3D printing the mould and casting the piece in stainless steel.
