Mineraalivärit

Mineraalivärit, known in English as mineral pigments, are coloring agents derived from naturally occurring minerals. These pigments have been used for millennia in various applications, including art, cosmetics, and construction. Their popularity stems from their durability, lightfastness, and often vibrant hues.

The process of obtaining mineral pigments typically involves mining the raw mineral, followed by purification and grinding to achieve the desired particle size and color intensity. Some common examples include ochres (iron oxides), which produce shades of yellow, red, and brown, and lapis lazuli (lazurite), historically used to create a brilliant blue known as ultramarine. Other notable mineral pigments include malachite for green, cinnabar for red, and azurite for blue.

Historically, mineral pigments were the primary source of color for artists and artisans. Their natural origin meant that their availability and cost varied geographically. While synthetic pigments have largely replaced many mineral pigments in mass production due to cost-effectiveness and consistency, mineral pigments continue to be valued in specialized fields. Artists often prefer them for their unique character, historical authenticity, and perceived environmental benefits. In cosmetics, certain mineral pigments are still widely used for their safety and opacity. The construction industry also utilizes mineral-based pigments for coloring concrete, plaster, and tiles, benefiting from their weather resistance.
