From the series 'Subtraction as Addition'

Hefti, Raphael
Hefti’s sculptural pieces reveal his interest in the aesthetic potential of chemical processes and technical procedures. The series 'Subtraction as Addition' features double glazed and colourful units of glass intended to be displayed propped against a wall, across a corner or in front of a window. To create them, Hefti exploits accidents in the process used to make the non-reflective glass which almost imperceptibly covers paintings in museums around the world. By pushing the production process to their extremes, Hefti makes the glass anything but invisible, creating abstract compositions on the surface and maximising the use of light. The result is a beguiling play of filtered light, morphing colour and shifting relection.
