'My Picture Is A Sum Of Destructions', Pablo Picasso (1881-1973)
During the 20th Century, an extremely complex change took place in the art of painting. Creative adventure was redefined and visual experience developed in new ways. The manufacture of synthetic materials provided artists with an enormous range from which to choose and allowed them to explore new territories technically. Different resins were tried. Three of these became the most important classes of synthetic resins that developed during the 20th century for use as binding media in paint and varnish formulations; alkyds, acrylics and polyvinyl acetates (PVAs). Along with the range of numerous types of synthetic media, a full line of modern synthetic pigments (both inorganic and, increasingly, organic) also became available to paint manufacturers.'I can hardly understand the importance given
to the word
research in connection with modern painting.
In my opinion to search means nothing in painting.
To find is the thing.
Nobody is interested in following a man who, with his eyes fixed on the ground, spends his life looking for the pocketbook that fortune should put in his path. The one who finds something no matter what it might be even if his intention were not to search for it, at least arouses our curiosity, if not our admiration.'Statement by Pablo Picasso, 19231
A project to study the influence that synthetic painting materials had on the technique of Pablo Picasso is underway at the Tate Gallery. This is the subject of my MPhil research. My research strategy is to subject fourteen Picasso paintings from the Tate's Collection to a strict programme of examination and detailed analysis (Figure 1). In addition, a number of paintings from other museums and private collections are to be sampled.
As early as 1912, Picasso used materials that were commonly used for other well-defined purposes besides fine art practice, such as household or architectural use and even industrial coatings, which he used along with artists' paints. During his cubist period he solved his problem of achieving bright colour by introducing Ripolin (shiny house paint) instead of artist's oil paint. In talking about the Ripolin paints, he named them, 'le santé des couleurs, (that is why) they are the basis of good health for paints'2 .
The use of Ripolin was an assault on the integrity of the painter's traditional medium. Picasso also influenced many other painters in the use of modern materials. Picasso's techniques and working methods, his justification for his choice of materials and the results of his choices on the appearance of the paintings are the primary subjects discussed. I hope, through the technical analysis of a number of paintings, to be able to indicate the periods that mark transitions for Picasso in which he adopted new materials in his creative expression.During the 1940s, Picasso's photographer and friend Brassaï, gathered a rich source of information from his notes of visits to Picasso. This is how he described Picasso's order for colours:
In an attempt to identify the materials that Picasso used in making these paintings, samples have been taken for analysis. The analysis of synthetic painting materials is not widely established, in contrast to the traditional ones. However, the Tate has recently developed analytical techniques that are capable of identifying such materials. Analysis of pigments and extenders is underway in the Tate's Science Section, by making cross-sections and dispersions for ultraviolet fluorescence microscopy, microchemical colour reactions, energy dispersive x-ray analysis (EDX), and X-ray diffraction (XRD) analysis.'Then the man in the blue suit reaches into his pocket and takes out a large sheet of paper, which he carefully unfolds and hands to me. It is covered with Picasso's handwriting-less spasmodic, more studied than usual. At first sight, it resembles a poem. Twenty or so verses are assembled in a column, surrounded by broad white margins. Each verse is prolonged with a dash, occasionally a very long one. But it is not a poem: it is Picasso's most recent order for colours:
White, permanent------------------------
argent --------------------------
Blue, cerulean---------------------------
cobalt-------------------------
Prussian----------------------
Yellow, cadmium lemon (clear)------------
strontium----------------
Lake, madder ---------------------------
blue and brown-----------
blue violet-----------------
Black, ivory--------------------------------
Ochre, yellow and red--------------------
Ultramarine, clear and deep--------------
Umber, natural and burnt------------------
Red, Persian-----------------------------
Green, cadmium, clear and deep------------
Sienna, natural and burnt-------------------
Green, emerald-------------------
Japan, clear and deep----------------
Veronese---------------------------
Violet, cobalt, clear and deep-----------------It made one think of Rimbaud's "Les Voyelles". For once, all the anonymous heroes of Picasso palette trooped forth from the shadows, with Permanent White at their head. Each had distinguished himself in some great battle - the blue period, the rose period, cubism, "Guernica"… Each could say: "I too, I was there…" And Picasso, reviewing his old comrades-in-arms, gives to each of them a sweep of his pen, a long dash that seems a fraternal salute: "Welcome Persian red! Welcome emerald green! Cerulean blue, ivory black, cobalt violet, clear and deep, welcome! Welcome!"'
Brassaï's notes, Thursday, November 18, 19433
Binding media in Picasso's paintings are characterised by pyrolysis-gas chromatography-mass spectrometry (PyGCMS) and Fourier transform infrared spectroscopy (FTIR). The problem in identifying early 20th Century housepaints lies in distinguishing them from oil paint, as both were based on linseed oil. Later alkyds also derived from oil and, moreover, sometimes they were mixed with oil on the artist's palette before the application to the canvas4 (see Francesca Cappitelli's article in this issue of the V&A Conservation Journal).
Besides the identification of the components of a great number of samples, the information that I find most helpful comes from their origin. Picasso was a master of painting techniques; if he was using traditional materials but found an area that required a paint of extra brilliance, he would simply add medium or change the type of paint that he was using (Figure 2). Sometimes he would simply squeeze from the tube the first colour he found on his table. Consequently, the analysis of the media in several colours from the same painting, shows that several types of colour were used in each.
Observing the painted surface under the microscope in order to devise the sampling strategy, I came to respect how his choice of materials is inseparable from the visual authenticity achieved in each painting. An understanding of the complexity of the surfaces is crucial, as Picasso didn't follow a systematic application of successive paint layers to the stretched canvas.The comparative study of photographs taken of each work, within the visible, infra-red (IR) and ultraviolet (UV) section of the spectrum as well as the X-ray, properly confirm Picasso's comment:
'The old days' pictures went forward toward completion by stages. Every day brought something new. A picture used to be a sum of additions. In my case a picture is a sum of destructions. I do a picture - then I destroy it. In the end, though, nothing is lost: the red I took away from one place turns up somewhere else.'
Statement by Pablo Picasso, 19355
What began as a preliminary investigation of materials and techniques led to a thorough appreciation of Picasso's technical skill.
Picasso had no desire to hide the process of painting6. In most cases he left visual clues on the surface of the final painting. Often the alterations that were made in a painting could be first detected by using simple visual methods like raking and transmitted light or by a more detailed observation using a simple microscope. The result of an alteration on the painting may be observed as a certain crackle pattern, a different colour showing through a crack or an unusual anomaly on the surface.
To confirm observations that are the result of his active brushwork, infrared light and X-rays are used to penetrate the visible image. Comparison of the x-radiograph mosaics and the infrared photographs with the visible image of the paintings often surprises by revealing not only paint changes but also a hidden image (Figures 3-5).
Are we entitled to uncover an image that the artist reworked for some reason? Knowledge of an earlier painting or a previous version, enables researchers to follow in their imagination the steps that the artist took in realising his inspiration. Picasso expressed his thought about this, giving us the green light!
'It would be very interesting to preserve photographically, not the stages, but the metamorphoses of a picture. Possibly one might then discover the path followed by the brain in materialising a dream.'
