Scientists have recognized the origins of the blue colour in one in all Jackson Pollock’s work with a bit of assist from chemistry, confirming for the primary time that the summary expressionist used a vibrant, artificial pigment often known as manganese blue.
“Quantity 1A, 1948,” showcases Pollock’s basic fashion: paint has been dripped and splattered throughout the canvas, making a vivid, multicolored work. Pollock even gave the piece a private contact, including his handprints close to the highest.
The portray, presently on show on the Museum of Trendy Artwork in New York, is nearly 9 toes vast. Scientists had beforehand characterised the reds and yellows splattered throughout the canvas, however the supply of the wealthy turquoise blue proved elusive.

In a brand new examine, researchers took scrapings of the blue paint and used lasers to scatter mild and measure how the paint’s molecules vibrated. That gave them a singular chemical fingerprint for the colour, which they pinpointed as manganese blue.
The evaluation, printed Monday within the journal Proceedings of the Nationwide Academy of Sciences, is the primary confirmed proof of Pollock utilizing this particular blue.
“It is actually fascinating to know the place some putting colour comes from on a molecular degree,” mentioned examine co-author Edward Solomon with Stanford College.
The pigment manganese blue was as soon as utilized by artists, in addition to to paint the cement for swimming swimming pools. It was phased out by the Nineteen Nineties due to environmental issues.
Earlier analysis had urged that the turquoise from the portray might certainly be this colour, however the brand new examine confirms it utilizing samples from the canvas, mentioned Rutgers College’s Gene Corridor, who has studied Pollock’s work and was not concerned with the invention.
“I am fairly satisfied that it might be manganese blue,” Corridor mentioned.
The researchers additionally went one step additional, inspecting the pigment’s chemical construction to know the way it produces such a vibrant shade.
Scientists examine the chemical make-up of artwork provides to preserve previous work and catch counterfeits. They will take extra particular samples from Pollock’s work since he usually poured immediately onto the canvas as an alternative of blending paints on a palette beforehand.
To resolve this creative thriller, researchers explored the paint utilizing numerous scientific instruments – equally to how Pollock would alternate his personal strategies, dripping paint utilizing a stick or utilizing it straight from the can.

Within the examine, researchers name the art work “a quintessential instance of his motion portray method the place ropes of colour, drips of black, and swimming pools of white coalesce into the layered dynamism that defines his fashion.” Whereas the artist’s work could seem chaotic, Pollock rejected that interpretation. He noticed his work as methodical, mentioned examine co-author Abed Haddad, an assistant conservation scientist on the Museum of Trendy Artwork.
“I really see loads of similarities between the best way that we labored and the best way that Jackson Pollock labored on the portray,” Haddad mentioned.
Art work by Pollock, who grew to become a sensation on the New York artwork scene within the Forties, has popped up in uncommon locations over time.
In 2023, authorities in Bulgaria mentioned a portray seized by police throughout a raid was seemingly a little-known work by the artist.
In 2017, a portray present in a storage in Arizona was believed to be a Pollock art work value $15 million.
