Minerals are inorganic compounds abundantly given by Mother Earth and are rich sources of metallic ions, mineral salts and metal oxides and sometimes used for extraction of certain pigments to dye a yarn. Minerals are drawn out by mining and exploration techniques and once extracted the pigment is suspended in a medium and the medium bonds with the cloth. These mineral pigments works best with natural fabrics like cotton, linen, hemp, wool, and silk. Earth pigments are known for their light-fastness (how resistant to fading it is when exposed to light) and fast drying. Explore more about the minerals used for extracting pigments.
