Dutch Design Week, it’s a wrap! 🤍

A big thank you to BioArt Laboratories for hosting Liquid Relic, and to everyone who stopped by and sparked interesting conversations.

It was lovely to share the latest developments of Liquid Relic, my ongoing exploration of transforming wastewater residues into glass.

Thank you for all the interest and encouraging responses. I’m excited to see where this will lead next!

✨ The Liquid Relic glass jewellery is available for purchase. Feel free to send me a DM if you’re interested in a piece.

Printing with the remnants of wastewater.

Exploring screen printing with fly ash and bed ash sand from sewage sludge incineration, fused between layers of glass.

Part of Liquid Relic, my ongoing research into the material possibilities of wastewater residues.

Developed during experiments at Make Eindhoven

On view at Dutch Design Week, 17–25 October, at BioArt Laboratories

What remains after an experiment?

A collection of crucibles, each holding the traces of a different glass experiment with residues from wastewater treatment.

What remains after we clean our water? 💧🔥

Fly ash and bed ash sand. Two residues from the incineration of sewage sludge, and the starting point of Liquid Relic.

Through glass, these overlooked materials reveal new possibilities, carrying traces of the hidden systems behind our everyday water use.

Today I said goodbye to AMFI after six and a half wonderful years of teaching.

Grateful for all the students and colleagues along the way. I've learned just as much as I've taught.

Looking forward to what comes next. 🤍

What if clothing had a voice?

Over the past year, together with Dagan Cohen, I have been developing (The Clothing Party): a speculative political party that uses the language of politics to look at clothing as a participant in the systems that shape our daily lives.

During State of Fashion, we brought The Clothing Party to the council chamber of Arnhem. In a staged council meeting, designers, makers, entrepreneurs, researchers, students, policymakers and city councillors gathered to debate the future of clothing and policy. Together we explored how municipalities can support a more caring, local and circular clothing system.

The Clothing Party is ongoing. If this resonates with you, I would love to hear your thoughts.
