“Cocoon” silk light sculpture by Julian Melchiorri made from silk protein nano optics #ArtTuesday

Via My Amp Goes to 11.

Cocoon is a light sculpture that explores the relationship between materials, light and our sensorial perception of them.

Cocoon is made by silk protein nano optics fabricated by Julian while he was working in lab exploring silk protein properties.

Julian firstly synthesized the protein solution directly from worm silk and crafted 2700 nano-prisms per millimetre on its surface thanks to Electron Beam technology.

Light is an electromagnetic radiation having a wavelength in a range of 400 nanometres. Each section of this wavelength is perceived by us in colours from blue to green and red.
When we look at a light emission we usually perceive a white source due to the smallness of its wavelength that unify all the colours.
When a ray of light passing through the material get diffracted by the nano-prisms, the light wavelength is sparse till its real composition get revealed.

Cocoon is lighted up by a single 1Watt Led. The light is scattered and diffracted by multiple layers of bio-optics meticulously placed in space to create the desired effect inspired by natural structures and fractal patterns.

The 3D printed structural shape derive from a digital transformation of a series of physical shapes previously 3D scanned.

Cocoon illustrate the metamorphosis of light, material and shape through multiple technological interventions, questioning the reliability of our sensorial perception of reality.
