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 volcanic soil. There are only 2 by-products of this process – volcanic soil sediment, and water. Both of which can go straight back into nature.

Made with volcanic soil created 3.8 billion years ago

If you think of volcanic soil, you might think of the debris caused by lava spewing out of a volcano, the aftermath of Pompei, or the dystopian sets of sci-fi movies. But volcanic soils were also generated by geological transformations that took place on Earth up to 3.8 billion years ago, when thermal changes to the planet’s crust created carbonaceous rocks and sediments. A mixture of carbon and amorphous carbon crystals, volcanic soil is formed when heat and pressure is applied to carbonised matter.

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.
