Cobalt Blue Watercolor Ink

Description

Cobalt Blue Watercolor Ink is our exquisitely hand crafted watercolor ink made with an extremely concentrated, high quality single source pigment. Every bottle is meticulously hand mixed, poured, and sealed, using water, pure local honey, natural gum arabic, a small amount of food grade sodium benzoate preservative, and less than 1% bentonite to slow settling and aid reincorporation. Every ink is single pigment with maximum concentration and no fillers or extenders.

Cobalt Blue has exceptional lightfastness, making it highly durable for both classical and contemporary artwork. It blends seamlessly with other pigments, offering rich, natural blues in painting. Its semi-opaque quality allows for excellent layering, depth, and shading in oil, watercolor, and tempera applications. Compared to other blues such as Phthalo Blue or Prussian Blue, it provides a more clear chroma, making it ideal for landscapes, skies, portraits, and abstract works.
