There is a recurring blind spot in contemporary design culture and “Mold”, the new exhibition he is editing Proof of Concept at the Aram Gallery in London, puts it in focus. Running until April 18, 2026, the show brings together twelve designers and studios, spanning ceramics, glass, furniture and more, and asks them to make their processes visible.
Less concerned with the usual refined effects, Mold shows the true nature of construction: the messy, precise, iterative, often unresolved reality of being something in the real world.

Proof of Concept was founded in 2024 by David Irwin, Smith Mathiasand Atelier Thirty Four especially to address this kind of gap. The platform wants to highlight and celebrate the realities of innovation, believing that design culture produces too many images and not nearly enough exploration of the thinking behind objects, and that the processes, failures and iterations that shape them deserve to be seen. For their third show, each participating designer was asked to work with the theme of molding and present their finished work along with details of how it came about.
The participants are a well-chosen mix, offering a wide range of mold making. Alt Studios contributes micro-concrete castings, showing how the material can be used on an architectural scale. Martina Claesson’s blown glass containers converse with extruded ceramics by Elliott Denny, Emma Louise Payne and Phoebe Stubbs, while David Irwin presents a PET press chair.
Gemma Matthias, co-founder of Proof of Concept, says: “Our aim is to highlight the depth of experimentation and iteration in product creation, particularly in an age of glossy, fleeting images. The mold is fundamental to how so many objects are created, ranging from improvised to highly technical processes, but all require craftsmanship and understanding. Prohibitively expensive, making it a real challenge to reproduce or test pre-production molds. This exhibition highlights how different disciplines address these limitations, revealing the different ways designers approach the complexities of mold making.
The economic reality is one that does not shy away from the exhibition and the overall curatorial work. Many projects never reach production, not because they failed as designs, but because tooling costs make scaling impossible, allowing emerging designers to work with a limited range of materials and processes.
The report also shows the importance for a designer to fully understand them proceduresto be able to use them properly or even innovate them. The shift to digital design tools has made it easier than ever to propose objects that look resolved on screen but present serious problems in manufacturing. The limitations of physical matter cannot be overcome with better software, and the lack of knowledge of them causes work to be compromised, unable to realize its full potential.
What Aram and the Proof of Concept it ultimately reveals is that good design comes from people who understand how things are made, who spend time in labs and factories, and that this understanding needs to be visible, teachable and valued. While AI-generated images make it almost too easy to visualize objects, and global supply chains have separated many designers from their factories, this argument is more relevant than ever to keep creating good design.
