Textile designer Amandine Brun Sauvant explores materiality at the intersection of craftsmanship and rigorous research, placing the chemistry of natural dyeing at the core of her practice. By harnessing the reactions of mordants such as alum and iron within fibres, she transforms chemical processes into a contemporary visual language. Instead of merely coating the surface, her colours are structured from within, capturing the memory of artisanal gestures through lines of tension. Deeply rooted in her territory, she uses local resources and botanical by-products to envision colour as a living, sustainable ecosystem.
