Madrid-based Mayice Studio, a multidisciplinary product design and architecture practice, was established in 2013 by Imanol Calderón Elósegui and Marta Alonso Yebra. With a sharp focus on materials—respecting both history and functionality—each design by Mayice Studio is presented with its own inherent personality, and aims to reflect the soul of a material. In much of Mayice Studio’s work, we find an intelligent dialogue between craft and technology. The Filamento light is an especially pertinent example: a sculptural piece made of a single length of curving glass, Filamento is a study of how light travels through concave and convex forms. When illuminated, the effect is a laser-like ‘filament of light’, that extends from one end of the lamp to the other. When the light is off, the design has a wonderfully ornamental appearance. Filamento is available in both horizontal and vertical configurations. Mayice Studio has experimented with glass in other lighting designs, including the bijou Blow Lamp and the Rfc+ suspension lamp collection, designed for the Royal Glass Factory of La Granja and made using a number of historic moulds.
