For the PRISM bench and cabinet, Yoshioka bevelled the edges of thick, high-transparency glass, creating striking colour diffractions in the sunlight.
By using the bevelling technique on a glass surface, the furniture gives off transparent glitters like a prism, he says.
The hyper-minimalist, boxy pieces are shorn of all detail, making the changing colour spectrums at its edges all the more beguiling.
PRISM Bench and PRISM Cabinet will be unveiled at Salone del Mobile 2015.
The designer has long had a fascination with transparency and reflection and has produced numerous designs exploring the properties of glass, crystal and plastic. His KOU-AN Glass Tea House is a traditional Japanese house made of clear glass that will be exhibited at Shogunzuka Seiryu-den in Kyoto. The PRISM designs are an evolution of previous collaborations between the Yoshioka and Glas Italia. He debuted PRISM in 2013 with a series of wall-mounted mirrors and mirrored furniture, followed by the launch of the PRISM mirror table and glass chair in 2014.
