 Why Was Ultramarine Paint So Precious?

One of the most famous colours used by Renaissance painters is Ultramarine. It is a magnificent deep blue colour made from ground Lapis Lazuli; a semiprecious stone mined in Afghanistan. 
Artists prized the intense blue shade of Ultramarine paint throughout history. It was used by some of the most famous painters in the world, including Vermeer, Michelangelo and Leonardo da Vinci. The early use of Lapis Lazuli as a pigment comes from 6th and 7th-century cave paintings in Afghanistani Zoroastrian and Buddhist temples. This beautiful shade symbolised holiness and humility during the middle ages and renaissance, and artists used it to paint the robes of the Christ Child and the Virgin Mary in religious paintings, such as Sassoferrato's painting, The Virgin in Prayer, below
Ultramarine paint was highly prized as it was more expensive than gold. Dutch artist, Johannes Vermeer was noted for his use of Ultramarine, and we have included an image of his work, Girl with a Pearl Earring above. Ultramarine paint was used on her headscarf as a blue, and mixed to create the shadows on her jacket. Read more about this painting here. In 1826, a synthetic version of the shade was invented and made accessible to the masses; this colour is known as French Ultramarine and is slightly more vibrant than the original colour. 

What Is Vermillion Paint?

 Vermilion is a rich, orange-red colour made from cinnabar, a form of mercury sulfide. Cinnabar is a naturally occurring mineral in several parts of the world, including China and Spain. Mining this material is very dangerous and challenging, as mercury is poisonous, and it's dangers were known as far back as ancient Rome, where mining cinnabar was known to be a lethal occupation. Wealthy Romans used the resulting paint to paint luxurious buildings. Archaeologist and ethnologist Anne Varichon's book, Colours, includes a report from Pliny stating that the painters of Villa Dei Misteri stole lots of the expensive pigment by frequently washing their brushes and saving the wash water. Due to its toxic nature, alternatives to Vermillion have been used since fourth century China.

Today we can enjoy the safe option of cadmium red, a synthetic shade invented in 1919. An interesting property of Vermilion is that it changes colour over time; you can see this in the painting, Niccolò Mauruzi da Tolentino at the Battle of San Romano by Paolo Uccello. The horse's bridle was painted with Vermillion and is now dark brown, where it was originally red.

 How Is White Lead Paint Made?

White lead paint was a popular choice for artists, but due to restrictions surrounding its sale because of its toxic content (poisonous lead), titanium white is now the preferred shade.
How was white lead paint made? It's a chemical process that begins with thin strips or buckles of metallic lead placed in earthen pots over vinager. These pots are stacked and covered with fermenting manure or tanner's bark to produce heat and CO2. After twelve to fourteen weeks, a chemical reaction has taken place, transforming the grey lead into white, which is then scraped, dried, and ground into a paste.

Did The Colour Of Napoleon's Walls Play A Role In His Death?

Scheele's Green and Paris Green are two vibrant green colours popular in the Victorian era. You can find examples of Paris Green in works by famous artists including J.M.W Turner, Monet, Renoir, Gaugin, Cézanne and Van Gough. Manufacturers used these shades in wallpaper, toys, candles, bed linen and even foods. Unfortunately, they were made of arsenic, which is toxic and has carcinogenic effects. Arsenic exposure can lead to seizures, coma, and death, and even low exposure levels can cause skin and lung irritation.
Why was exposure to Scheele's Green and Paris Green wallpaper so dangerous? Experts theorise two causes - dust particles caused by pigment and paper flaking and toxic gas production. Over time, minuscule fragments of pigment can flake off the walls into the air in the room to be inhaled. Toxic arsine gas can be released from the dye if the room is damp or mouldy. Napoleon was exiled to St Helena island, a tropical island with a humid climate. The house he lived in had rooms decorated in green - reportedly his favourite colour. He is thought to have died from stomach cancer; exposure to arsenic increases the risk of stomach cancer, and his hair's analysis also revealed high arsenic levels. 

Malachite: Admired Since Ancient Egypt 

Malachite is a captivating green copper carbonate that can be ground and purified to make paint. The resulting powder is comparatively coarse, as the colour fades the finer it is ground. Malachite pigments decorated Ancient Egyptian tombs, and it is thought to be one of the oldest known green paints.

The colour of solid malachite ranges from deep green to light green, with bands of lighter and darker shades. In its purest form, malachite has an intense deep green colour, but most specimens contain spots or circles of lighter or darker greens. Malachite is also known as Bremen green, olympian green or iris green.

Orpiment: A Deadly Shade of Yellow

Orpiment is a lemon or canary yellow shade, also known as King's yellow. It was a bright yellow paint used in the eighteenth century. Volcanic orpiment has been a valued commodity since the Roman Empire and is gathered from sulphurous fumaroles (natural gas vents around active volcanoes). Magnificent example below, Orpiment Crystals from Twin Creeks Mine, Potosi District, Humboldt County, Nevada, USA. 

Preparing this pigment is a highly complicated process that requires manual labour at every stage, from selecting crystals and removing impurities to grinding them into a powder, breaking them by hand if needed, and finally chemically separating the sulfur before being heated for use in paint.

Unfortunately, orpiment is highly toxic due to its high arsenic content, making it extremely dangerous. Its beautiful golden colour also appealed to alchemists searching for a way to make gold from base materials. You can see an example of its use in the painting Happy Union by Paolo Veronese. 

Madder Lake: A Red Colour Made From A Plant

Madder Lake is a vivid red pigment that originates from the root of the madder plant (Rubia tinctorum). Artisans have used it throughout history to lend beautiful shades of reds and pinks to their work as a paint or fabric dye. An early example of this practice was used in India, where researchers discovered cotton dyed with madder dating to the 3rd millennium BCE. 

The production process begins with drying out the Madder root. It is then crushed and separated from the bark. The substance is then ground with stones and made into a powder. Before using it as a paint or dye, Madder lake must be mixed with other ingredients like clay or alum. 

Artists could apply Madder lake paint over a coat of vermilion paint (a bright red shade with an orange tint); this layering technique enhances the vermillion colour and prevents colour fade. This process is used to colour in the dress featured in The Girl with a Wine Glass by Vermeer.

Bone Black: Inspiring Artists Through The Ages

Bone black paint has a long and storied history since ancient times and has been noted in Egyptian, Greek and Roman art. It has remained in use throughout the Renaissance to modern times. The paint is made by burning animal bones in an oxygen-free environment, such as a kiln or oven until it is reduced to charcoal or ash. Historically, waste ivory was also used instead of bone, but this is not in practice today due to environmental and cost considerations. 

Bone black can also be combined with other colours to create a wide range of hues, from light greyish-black to deep blue-black tones. You can see an example of bone black in the clothes in the painting below, Portrait of Philips Lucasz by Rembrandt. 

Vandyke Brown: Creating Shades and Shadows

Vandyke brown, also called Cassel earth or Cologne earth—is a dark brown colour named after the 17th-century Flemish painter Anthony van Dyck. This pigment is traditionally made by blending various types of peat and soil from Germany's Cologne and Kassel regions. This pigment has been used in oil and watercolour paintings since the 17th century, with its popularity increasing in the 19th century. Old Masters such as Rubens used it mixed with gold ochre to create a transparent brown hue.  Rembrandt also used it to create dark atmospheric backgrounds, such as his painting of Saskia van Uylenburgh as Flora, below.
