Introduction to Ultramarine Blue
Ultramarine blue is derived from the semi-precious stone lapis lazuli, which is primarily found in Afghanistan. The name “ultramarine” itself reflects the pigment’s origins from beyond the seas (ultra marine), highlighting the extensive trade routes that were established to bring this precious material to European artists. The pigment has been highly valued for its lightfastness and durability, making it a staple in the palettes of many famous artists throughout history, including Michelangelo and Vermeer.
Historical Production of Ultramarine Blue
Traditionally, the production of ultramarine blue involved grinding lapis lazuli into a fine powder. However, not all of the stone is usable for pigment; only the portions with the highest concentration of the mineral lazurite, which is responsible for the blue color, are suitable. The process of extracting the pigment from the stone is labor-intensive and expensive, which historically made ultramarine blue one of the most costly pigments available, often more valuable than gold.
The traditional method of producing ultramarine blue pigment from lapis lazuli involves several steps:
– Grinding the lapis lazuli into a powder to release the lazurite.
– Mixing the powder with a binding agent, such as egg, to create a paint.
– The mixture is then applied to the desired surface, where it dries to form a durable, long-lasting pigment.
Chemical Composition and Lightfastness
The chemical composition of ultramarine blue, primarily consisting of sodium aluminum silicate with sulfur, gives it its characteristic color and outstanding lightfastness. Lightfastness refers to the pigment’s ability to resist fading or changing color when exposed to light, a critical property for artworks intended to endure for centuries. The unique structure of the lazurite molecules absorbs light in a way that produces the deep blue color, while also being remarkably stable over time.
Modern Production of Ultramarine Blue
In the early 19th century, a synthetic version of ultramarine blue was developed, significantly reducing the cost and increasing the availability of the pigment. This synthetic ultramarine blue is produced through a process involving the heating of kaolin, silica, and sodium carbonate, along with sulfur, in a high-temperature furnace. The resulting product has properties very similar to those of the natural pigment, including its color and lightfastness, but at a fraction of the cost.
The modern production process has made ultramarine blue accessible to a wider range of artists and applications, from fine arts to industrial coatings. However, the synthetic version, while very close in appearance and performance, lacks the historical and emotional value associated with pigment derived directly from lapis lazuli.
