Designed by Studio ThusThat
In the early stages of aluminium production, factories cast molten aluminium into massive blocks weighing in at over 25 tonnes. These blocks are clad with undulating, organic textures that are a result of the casting process. In the preparation of the blocks to be sent to other factories, the sides are cut off, leaving behind thin plates with organic, undulating surfaces–known as “crusts”.
ThusThat, in a continuation of their exploration of industrial narratives, use these crusts to create the first of an ongoing series of interior objects that reflect the unexpectedly raw backstory to an everyday material. The edges are jagged and roughly cut, resulting in rugged forms that seem to have been themselves byproducts of some industrial mechanisms, contrasted by a polished finish. The backside of the plates still show traces of the giant saws of the factories from which they were cut.
The pieces are designed to be easily disassembled, and recycled.

Slight variations may apply due to a handmade production process.
The body of each piece is made using slag in the ‘geopolymerisation’ technique–an entirely new breed of cementitious materials that have substantially lower CO2 footprints. The slag is the active binder (the ‘cement’) and filler; no cement, no resin, and no other binders are used. The pieces are formed manually by hand around an inner form-work, and finished with another slag mineral sealant.
The copper is hammered in a tradition manner to coppersmiths, albeit with a twist that allows for a frame-like form and pronounced textures. The natural patina of tempering is left on the underside of the copper, and the pieces are secured to the body with brass fittings.

This Is Copper Collection
Copper is ubiquitous to our modern world, yet it is largely invisible. It is the first metal used by humankind, and it is crucial for a renewable future: a wind turbine alone can contain up to five tonnes of copper, and ten tonnes of the metal are needed per kilometre of high-speed railway.
But what exactly is copper? The metal we know is only part of a much wider material story. Mining overburden, tailings, metal concentrates, rare metals like gold and silver, sulfuric acid, sulphate solution, slag, and more.
All of this is copper, or in other words is a direct result of processing, using, and recycling copper. This project exposes and proposes potential uses for some of these overlooked byproducts as the search for evermore copper continues.
About the designer
Led by KevinRouff and Paco Böckelmann, ThusThat bridges collectible design with material science to create pieces that are strong, simple, and direct in form, keeping the complexity packed within the materiality itself. Their work with wastes of the mining and metallurgy industries have received widespread recognition, exhibition, and international awards, with pieces in the permanent collection of the London DesignMuseum and Design Museum Gent.
