Congrats to James Walsh Studio for winning the 2020 Australian Furniture Design Award with his entry Anthropic Bench.
The Anthropic Bench – Made from locally sourced soil and recycled glass, combined in a process that dates back to 5000 BC.
The objective of this project was to explore the rammed earth process and to see how recycled materials could be added without the loss of its structural properties.
Over the course of a month, various combinations of glass particle sizes, soil mixtures and stabilisers were explored to develop a material that could compete with the current standard of rammed earth.
This is typically a 90% mixture of soil and a 10% addition of stabiliser.
Through my research I found that today the stabiliser is typically cement, however traditionally animals blood was used (so interesting!). Throughout my experiments I came across a stable combination of materials which includes a 10% addition of glass particles, 10% stabiliser and 80% of soil.
Having produced custom formwork for this design using a CNC cut mould, the Anthropic Bench relies entirely on gravity and the designed taper, which allows the solid bench top to sit in place without the need for fasteners or adhesive.
