Cobalt Blue Turquoise Dark, PB 36

Cobalt Chrome Aluminate, frequently recognized as Cobalt Turquoise or Cobalt Blue-Green, is a premium Complex Inorganic Color Pigment prized by professionals for its brilliant, highly opaque teal hue and virtual indestructibility. Formed by calcining cobalt, chromium, and aluminum oxides at temperatures exceeding 1000°C, the heavy metals are safely locked into a rigid "spinel" crystalline lattice, resulting in a safe, inert pigment that will not bleed or migrate like many transparent synthetic alternatives. This exceptional structure provides a critical, solid covering power perfect for mixing vivid sky and water tones, while its intense manufacturing process equips it with unmatched durability across demanding applications, specifically including:

Absolute Lightfastness: It remains perfectly stable without fading, darkening, or shifting under UV exposure, making it ideal for outdoor murals.

Alkaline and Acid Resistance: It will not degrade in highly alkaline environments, making it a reliable choice for frescoes, concrete tinting, and silicate wall paints.

Extreme Heat Resistance: Because it was created in a furnace, it easily withstands the massive temperature spikes required by ceramicists and glass artists.

Painter's Note: This pigment is very easy to work with. Disperses easily into most binders due that the particle size is very fine. 

Lightfastness - thinned: 8 (1 is bad, 8 is best)
Lightfastness - medium: 8 (1 is bad, 8 is best)
Lightfastness - concentrated: 8 (1 is bad, 8 is best)
Suitability: Acrylics, Cement / Tadelakt, Ceramic, Lime / Fresco, Oil, Silicate binder, Waterglass, Tempera, Watercolor / Gouache
