Blue pigments are absent in Palaeolithic art. The authors identify traces of azurite on an artefact from the Final Palaeolithic site of Mühlheim-Dietesheim, Germany. This represents the earliest use of blue pigment in Europe!

Lac insects are the source of pigments used in dyes, paints, lacquer, and jewelry. The insects have two endosymbionts—the bacteria Wolbachia and a yeast-like symbiont, which produces its coveted bright red pigment, laccaic acid. In PNAS: www.pnas.org/doi/10.1073/...

The old windmills in Zaanse Schans are still in service. Their enormous milling stones are used to grind grains into flour and meal, or minerals into vibrant pigments. Those pigments would be added to binders for paints and dyes. #Vibrant #BlueSkyArtShow #Windmill #Dutch #Netherlands #Amsterdam
A case holding small apothecary style bottles of minerals milled into pigments. These pigments could be added to mediums such as linseed oil to color paints. This method being performed at the Dutch windmills for centuries. Some of the Dutch masterworks likely used paints made from pigments straight from these very windmills.

"The Egyptian Blue"

Egyptian Blue is the oldest known artificial pigment. The Blue color has been throughout the history of humanity, one of the most quoted, identified by it with royalty and divinity, due to the difficulty of its obtaining.

More info in the alt text 👇
Blue pigments were used from very old, but more late than others such as red, Black, brown or ochre, easier to get in nature and used already in the art art. But the most quoted blue pigment came from minerals such as lapis, scarce and rare, and therefore very expensive. The largest lapis deposits are located in the hindukush of Afghanistan, where they are still exploited with procedures very similar to employees more than 3.000 years ago. The Egyptians cared about those mines large amounts of lapis to obtain the azurite, the dust that provided the blue pigment with which they adorned their artistic works. Its price was so high that even in medieval times still cuadriplicaba the gold. That's why towards 3000 BC they sought a way to make their own blue pigment. Little by little they were perfecting the technique, which consisted of grinding silica, lime, copper and an alkaline base, and heat it at 800-900 degrees Celsius. The result obtained is considered the first synthetic pigment in history. The Egyptians used it to paint wood, papyri and canvases, coloring enamels, inlays and vessels. But especially in the funerary field in masks, statues and paintings of the graves, as they believed that the blue color protected the dead from evil in the other life. The oldest known example of the pigment dates from about 5000 years ago and was found in the painting of a tomb of the reign of ka-Sen, the last Pharaoh of the first dynasty. In the new kingdom the Egyptian Blue was used abundantly as a pigment being found in statues, paintings of tombs and sarcophagi.

‘Using period materials like “calcium carbonate that could have been drawn from limestone or seashells; quartz sand; and a copper source” heated to around 1,000 degrees Celsius… “the researchers prepared nearly two dozen powdered pigments in a stunning range of blues.”’
