Liquid Plastic – Coffee Table + Chair

Back to Bespoke Services

The Liquid Plastic Coffee Table and Chair continue to explore plastic as a sculptural medium. By using a composite of rigid expanding foam and marble dust, the pieces allow the material to largely dictate their form.


The pieces are made from a very dense polyurethane foam mixed with marble dust. Polyurethane foam is a thermosetting polymer in two parts. When the parts are mixed together a reaction occurs and the resulting liquid sets very rapidly. Marble dust (calcium carbonate CaCO²) is made from pure marble rock and is no larger than 150 microns in particle size. The dust is a byproduct of the marble industry.

The composite created for these pieces has a very short working life – it must be poured within minutes and changes it’s structural properties every second. This meant there was a very specific window in which it could be poured. Initially, this appeared to be a constraint, but it soon became an integral part of the designs and led to the creation of each unique piece.
