Vermeer's Palette: Natural Ultramarine


Origin, History and Characteristics

(oltremare, lapis lazuli)

Vermeer, as many painters of his time, employed a very limited palette. The only substantial difference in his palette in respects to those of his contemporaries was the extensive use of natural ultramarine (pure lapis lazuli) rather than the much cheaper azurite.

Natural ultramarine is made of the powder of the crushed semi-precious stone lapis lazuli which, after being thoroughly purified by repeated washings, is bonded to a drying oil through hand mulling. The exact proportions between pigment (powdered lapis lazuli) and vehicle (natural drying oil) and correct amount of hand mulling necessary to produce the highest quality paint can be only acquired by experience. Even when the process is mastered the resulting paint has a very fastidious stringy quality which makes it difficult to brush out evenly. However, mixed with white this defect is less noticeable. The final product is a very deep transparent blue. Set aside other pigments on the artist's palette, it is one of the darkest, only black is darker. Mixed with lead white, it maintains its radiant purity and brilliance even in the palest shades. The superior cost, complicated preparation and poor brushing qualities of natural ultramarine are offset by the exceptional brilliance and purity of the final product. Genuine ultramarine made of lapis lazuli is no longer produced and has been replaced by synthetically produced ultramarine blue.

Most painters used natural ultramarine economically in thin glazes over an opaque underpainting rather than in body color.

Looking Over Vermeer's Shoulder is a comprehensive study of the materials and painting techniques that made Vermeer one of the greatest masters of European art.

Bolstered by the author's qualifications as a professional painter and a Vermeer connoisseur, every facet of 17th-century and Vermeer's painting practices—including canvas preparation, underdrawing, underpainting, glazing, palette, brushes, pigments and composition—is laid out in clear, comprehensible language. Also investigated are a number of key issues related specifically to Vermeer's studio methods, such as the camera obscura, studio organization as well as how he depicted wall-maps, floor tiles, pictures-within-pictures, carpets and other of his most defining motifs. Each of the book's 24 topics is accompanied by abundant color illustrations and diagrams.

By observing at close quarters the studio practices of Vermeer and his preeminent contemporaries, the reader will acquire a concrete understanding of 17th-century painting methods and materials and gain a fresh view of Vermeer's 35 works of art, which reveal a seamless unity of craft and poetry.

While not written as a "how-to" manual, realist painters will find a true treasure trove of technical information that can be adapted to almost any style of figurative painting.

Natural Ultramarine in Vermeer's Painting

The use of natural ultramarine in Vermeer's painting could easily constitute a study in itself. Although genuine ultramarine can be found in almost every painting by Vermeer, it is truly surprising to what extent Vermeer actually employed the pigment. Not only is it found in blue colored objects themselves but upon close inspection traces can be found in the shaded portions of white drapery, ceramic jugs (fig. 1), black marble tiles, green foliage, white washed walls and even in the shadows of the brilliant orange gown in The Glass of Wine. A fine example of genuine ultramarine can be seen in the satin gown of Woman in Blue Reading a Letter (fig. 2), although it is now less brilliant today due to aging of the varnish. The gem-like depth of the wrap (fig. 3) in The Milkmaid is another. In this case, the excellent state of conservation of the painting allows us to appreciate in full the chromatic brilliance of pure lapis lazuli.

"In The Music Lesson, ultramarine was used for the shadow in the flesh tones of the male figure. It is also found combined in mixtures to produce a range of other colors: for example ultramarine has been mixed with red lake to form an array of purples such as the leaded lights, tablecloth pattern, man's sash and for shading the wall on the left. Most extraordinary, however is that the costly mineral blue pigment was used to produce the mixed brown of the ceiling beams, with the likely aim of achieving an integrated coloristic harmony."1

The ultramarine-containing paint used by Vermeer has sometimes blanched with time resulting in a generally paler color than it would have been originally in a number of areas, for example in the design of the tiles in The Lady Seated at a Virginal (fig. 4). The darkening of the binding medium and additional components present in the paint layers of the curtain and tablecloth in The Guitar Player make it difficult to be sure whether a dark purple-blue or blue-green color was originally intended for these fields of color.2

Vermeer's copious use of natural ultramarine seems to have reached an almost obsessive degree unless we understand just how perceptive was the artist's eye. Vermeer realized early in his career that the admixture of genuine ultramarine with tones of gray, usually composed of lead white, bone black and raw umber in varying proportions, lends them a characteristic luminosity produced by intense daylight which cannot be produced otherwise. This technique is to found only in Vermeer's paintings. Mixtures of blue in the shadows was to be employed many years later by the French impressionists to suggest the effect of full daylight.

Another example of Vermeer's extensive use of natural ultramarine can be found in Young Woman with a Water Pitcher. Obviously, it was used to paint the folded blue drapery on the table, in a more or less conventional way. It was also used in the window to render the incoming daylight which passes through the glass pains. Vermeer applied delicate opaque and semi-transparent layers of natural ultramarine mixed with white lead in varying proportions over the warm tone of the canvas preparation which in places can still be observed in order to register the varying degrees of intensity of light as it plays on and through the surface of the uneven glass. Observed with care, we can see that even the lead molding has been painted with lapis lazuli, this time Vermeer brushed genuine ultramarine mixed with only a very small quantity of white over the darker underpainting. The contrast between the bluish overtone of the glass and the warm toned sunlight portion of the window frame is absolutely natural. The head dress worn by the young woman was first modeled in shades of white and neutral gray. Once dry, Vermeer superimposed the pale shades of genuine ultramarine to render the candid transparency of the starched cloth inundated by sunlight. Natural ultramarine is even found in the light gray paint of the background wall.

Shadows of white objects are particularly difficult to integrate into the overall tonality of a painting. Dutch painters invariably used mixtures of black or raw umber to render the shadows of white objects and to deepen tones of local color as well. While this technique maintains a chromatic unity within the painting, it fails to suggest the freshness of natural daylight that Vermeer strove to capture.

Recent examination of the Lady Seated at a Virginal 3 has revealed that Vermeer combined precious ultramarine with the rather mundane green earth, a flat green pigment, to form a range of blue-greens for the lady's dress (fig. 5). Mixtures of ultramarine and green earth were also applied over an underpaint of green earth combined with black for the patterned curtain in this painting.
