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.

Made with a 3.5 billion year old mineral called hematite

Hematite is a mineral with an amazing history. It was first used by prehistoric humans to paint cave walls 164,000 years ago. Ancient Egyptians turned to it to heal wounds. And Leonardo da Vinci painted his masterpieces with it. But its origins go back even further. 3.5 billion years ago, gram-negative bacteria called cyanobacteria released free oxygen into the ocean. This combined with iron to make hematite, which sank to the seabed to form rocks that are still around today.

Minerals create a different kind of colour

Nearly all the colour you see in clothing today will have been created with petroleum-based dyes. But colour in clothing existed long before the chemical dyeing industry was invented. So we’ve gone back to the colour palette of early man. Because each t shirt is made using minerals made by nature, you might find small differences in colour across it. And because it’s garment dyed, every t shirt has a pre-worn look.
