The choice of the appropriate ink is a critical factor for artists, as it affects the aesthetics, longevity, and texture of the artwork. Inks originate from various sources, such as plants, minerals, and animal organisms, each with unique properties.

Plant-based inks are derived from plant extracts and have been used in art for centuries. Ink from walnut shells produces deep brown tones, while ink from French tea offers softer and more transparent results. These inks are biodegradable and environmentally friendly, though they are more sensitive to moisture and fading over time.

Mineral inks are made from ground minerals and provide vivid and stable colors. Lapis lazuli, also known as lazurite, gives a deep blue color, while azurite offers brighter blue shades. Dioptase is used to create vibrant green inks. These inks are lightfast and do not fade easily, although their preparation requires specialized processing and is quite costly.

Animal-based inks come from natural organic substances. Sepia ink is famous for its rich brown shades and has been used in art since antiquity. Black ink made from burned fish bones yields an exceptionally deep and stable tone.

The selection of ink depends on the artist’s needs and the desired outcome. Understanding the origin and properties of each type of ink aids in its optimal use, offering a variety of textures, colors, and durability over time. Both the raw materials and the knowledge of their characteristics are of great importance—not only for those who have the time and expertise to produce their own inks, but also for those who typically use commercially available inks. Having the relevant experience and knowledge allows them to make informed choices about their materials and use them effectively to achieve exactly the results they seek, ensuring their works endure unchanged for centuries.
