"Paul Cocksedge Studio was founded in 2004 by Paul Cocksedge and Joana Pinho. With a strong and dedicated team of collaborators, the Studio has won national and international acclaim for its original and innovative design, underpinned by research into the limits of technology, materials and manufacturing processes.

The key feature of the Studio’s work, in everything from product design to architectural projects, is a focus on simplicity and imagination in order to create unique people-centred designs. At the core of this focus lies an unrelenting attention to detail, a willingness to question previous assumptions about design, and an eagerness to take on a wide-ranging array of projects."

1st prize winner, ’The Bombay Sapphire Prize 2003’, International Glass Design Award.

"Hand made glass vessels filled with natural gas are charged with current and suspended. In daylight they are translucent with a hint of natural color. In the dark they have a unique and beautiful aesthetic all of their own with strikingly vivid colors. "

Each vessel is 10x10x50cm (4x4x20in.)

It is made with hand-blown glass and filled with neon gas, it glows in red when an electrical current passes through them.

The form is a reminiscent of some alchemist instrumentation.
