Lapis Lazuli - The King of Blues

The Stone of Heaven

 For over 6,000 years, lapis lazuli has captivated the human imagination with its deep,p celestial blue. First mined in Afghanistan's Badakhshan province around 4000 BCE, this semi-precious stone became one of the most prized materials of the ancient world. Its name derives from Latin "lapis" (stone) and Arabic "azul" (blue).

Lapis lazuli contains lazurite (blue), calcite (white veins), and pyrite (gold flecks). The ancient Egyptians used it for eyeshadow and adorned Tutankhamun's funeral mask with it, associating its celestial blue hue with divinity. The stone traveled westward along trade routes, becoming increasingly valuable—often worth more than gold by the Medieval period.


From Stone to Paint: Creating True Ultramarine

The transformation of lapis lazuli into pigment represents one of the most sophisticated processes in art history. As Cennino Cennini wrote in his 14th-century treatise: "Ultramarine blue is a color illustrious, beautiful, and most perfect, beyond all other colors."

Lapis Lazuli, known as PB 29 in modern colour standards, creates this precious pigment. The finest lapis lazuli comes from Afghanistan's Badakhshan province, producing stones with deep purplish-blue color. The mineral contains lazurite (blue), calcite (white veins), sodalite, and pyrite (golden flecks). Quality varies dramatically based on lazurite content—from light blue to deep purplish blue. Only gem-grade stones with solid blue areas and minimal pyrite veins produce the best pigment.

Creating lapis lazuli pigment requires careful processing in several stages. First, gem-grade stones are cut and crushed into coarse sand using a jaw crusher—a challenging process due to the exceptional hardness of the stone. The crushing releases a distinctive sulfur smell like burned matches.

The crushed material is thoroughly washed and wet-milled in a metal-free environment to prevent contamination. The milling process gradually reduces the particle size to under 50 microns, separating the blue crystals from colourless contaminants. Initially gray in appearance, the mixture develops its characteristic purplish-blue tone through careful size reduction and multiple pH-neutralizing washes. The final powder is air-dried before extraction of the pigment.

This labour-intensive process yielded pitifully small amounts of pigment—a pound of lapis might produce just a few grams of the finest ultramarine. Artists reserved it for the most sacred subjects, particularly the robes of the Virgin Mary. Michelangelo reportedly left his "Entombment" unfinished because he couldn't afford the ultramarine needed to complete it.


The Blue Revolution: Synthetic Ultramarine

The exorbitant cost created a strong incentive to find alternatives. In 1828, Jean-Baptiste Guimet claimed a French prize by developing synthetic ultramarine using kaolin, sodium carbonate, silica, sulfur, and carbon heated together at high temperatures. This "French Ultramarine" revolutionised, located south of Windermere at Backbarrow, operated by making luxurious blue accessible to all artists while transforming the textile industry.


Dolly Blue: Ultramarine in the Lake District

The Dolly Blue factory operated south of Windermere at Backbarrow from the 1870s until the mid-20th century. It produced laundry bluing—ultramarine-based powder that countered the yellowish tinge in white fabrics. The slight blue tint created an optical illusion, making whites appear brighter. The factory utilised water power from the River Leven and employed many locals, with distinctive blue bags of Dolly Blue becoming a household staple throughout Britain.


The Colour Maker's House: A Living Tradition in Appleby

In Appleby-in-Westmorland, the Colour Maker's House continues a 300-year-old tradition in a Grade II-listed townhouse dating back to 1677. Master colour maker Thomas Harrison explains: "The alchemists called it 'the stone of heaven.' When medieval monks ground lapis into ultramarine, they considered the act itself a form of meditation."

The workshop transforms raw lapis into ultramarine using traditional methods—mortar and pestle, then a glass muller on a marble slab. Hand-grinding allows the colour maker to feel the material's resistance and achieve perfect fineness. Sulfur remains crucial as a fixative, in creating golden yellows, and in small-batch ultramarine production.

"There's something alive about true ultramarine from lapis lazuli," notes apprentice Alice Harper. "It's not just the colour—it's the way it holds light, the way it seems to have depth. Commercial synthetic versions lack what the alchemists called the 'soul' of the colour."

Genuine ultramarine costs fifty times more than synthetic versions but offers unique qualities—subtle granulation effects, infinite depth in transparent glazes, and luminosity that seems to come from within. The workshop supplies historically accurate pigments worldwide while offering workshops to preserve traditional knowledge.


The Blue Thread Through History

This story reveals how a single colour weaves through history—from sacred stone to religious art, from industrial innovation to household product, from ancient wisdom to living tradition. The blue thread connects Afghanistan's mountains to Windermere's waters, medieval workshops to Victorian laundries, and extends to Appleby's 17th-century townhouse.

"Each jar of pigment we create carries forward knowledge that might otherwise be lost," reflects Harper. "When artists understand where their materials come from, it changes how they work. The painting becomes a conversation between artist, material, and the landscape that birthed the colour."

The Azure Trail continues, ensuring that future generations have access to materials that connect them to art's deepest roots—bridging sacred and practical, ancient and contemporary.

Working with Genuine Ultramarine - Artist's Tips


  • Thin applications: True ultramarine's intensity means a little goes a long way. Build up colour gradually through multiple thin glazes rather than applying it heavily.


  • Mixing companions: Pairs beautifully with earth pigments, particularly raw umber and burnt sienna. The slight warmth of genuine ultramarine prevents the harsh coolness that synthetic versions can introduce.


  • Granulation effects: The natural texture creates beautiful separations in washes. Embrace rather than fight this characteristic for unique atmospheric effects.


  • Permanence: Genuine ultramarine is completely lightfast and chemically stable. Unlike some historical pigments, it can be used with confidence in works intended to last.


  • Value your investment: Store in airtight containers away from light. The pigment itself is permanent, but the binding medium (if pre-mixed) may be affected by environmental factors.
