As we continue to look for new, low impact ways to dye clothing, we’ve turned to the colouring tools of early man – minerals, rocks, and soils. Minerals don’t just tell the story of life on Earth, they also tell the story of colour. When our solar system settled into its current shape around 4.5 billion years ago, Earth was created by a series of galactic collisions. Tectonic plates began to form. And geological life and biological life fused together to create vast mineral deposits in the Earth’s upper crust. So when prehistoric man first picked up a prehistoric paintbrush, they turned to the ground around them. Today, instead of using those minerals to paint cave walls, we’re using them to dye clothing. Our Mineral T Shirt is garment dyed in a giant bath of hematite. There are only 2 by-products of this process – sediment, and water. Both of which can go straight back into nature.
Black Algae Dyed T Shirt
Made with seaweed from Icelandic fjords, and the world’s first black algae dye.

Technical Details

The first piece of clothing dyed with black algae
Over the last few years we've been working with US biomaterials company Living Ink to accelerate the adoption of black algae as a way to colour clothing. After their founders Scott and Steve discovered that an algae cell is almost identical in size to a carbon black pigment, and can create the same colour, they’ve been on a mission to replace carbon black with black algae waste. Now, after 5 years of R&D and lab testing, this t shirt represents a major breakthrough on the journey – the first piece of clothing ever to be dyed with black algae.



Our intensive R&D process didn't stop with the dye
We carried out 6 months of lab tests to successfully dye our t shirt, trying different fabrics, dyeing temperatures, and pigment concentrations, before finding the perfect combination.
