Helen Frankenthaler
Helen Frankenthaler was a painter whose soak-stain technique let thinned paint enter raw canvas, changing postwar artists’ approach to the support.
Painter
Jackson Pollock was an American Abstract Expressionist known for pouring, dripping, and flinging fluid paint across canvases laid on the floor.
Before developing his drip paintings, Pollock explored Surrealism, especially its ideas about the unconscious and automatic methods of making art.

Pollock used commercial enamel and oil in his poured canvases, added aluminum paint to some works, and made watercolor and gouache pieces on paper.
MoMA identifies both oil and enamel in Number 1A, 1948. Working with a canvas spread on the studio floor, Pollock poured or dripped the more fluid commercial paint with sticks and other tools; handprints also appear near the upper edge. The enamels were industrial coatings, not a special paint made only for artists.
Oil appears alongside enamel in Number 1A, 1948 and Number 1, 1950 (Lavender Mist). LACMA also records No. 15, 1950 as oil on Masonite, showing that Pollock's poured and flung marks were not confined to large stretched canvases or to one type of paint.
The National Gallery of Art records aluminum paint alongside oil and enamel in Pollock’s Number 1, 1950 (Lavender Mist). The reflective metallic material contributes silvery threads among the poured and dripped lines. It is a documented component of this particular painting, not evidence that Pollock used metal leaf or metallic paint throughout his career.
The Met catalogs Pollock’s early Untitled (about 1938–41) as watercolor and gouache on cardboard. The transparent watercolor shares the sheet with opaque passages, documenting a works-on-paper practice before the large poured canvases of his mature period. It should not be conflated with the commercial enamel and oil in his later paintings.
Gouache appears with watercolor in the Met's cardboard Untitled (c. 1938–41). The museum also holds a separate Untitled from the same period made in gouache on paper. These opaque studies should not be confused with the oil-and-enamel mixtures of his mature canvases.

Collection entries identify canvas and paper among Jackson Pollock’s supports, with the examples below grounding each material in documented works.
Pollock made his best-known poured paintings on canvas, including MoMA’s Number 1A, 1948 and the National Gallery’s Number 1, 1950 (Lavender Mist). He placed large canvases on the studio floor and worked across them from multiple sides, allowing the support’s broad horizontal plane to receive poured, dripped, and flung paint.
Pollock made painted studies on paper alongside his large canvases. The Met records his Untitled (1938–41) as gouache on paper and holds several other works on paper, including studies combining gouache, watercolor, ink, and drawing media. These sheets document a compact, exploratory format distinct from the floor-worked canvases of his mature drip paintings.
The Met catalogs Pollock’s early Untitled as watercolor and gouache on cardboard. This rigid sheet carries a small-scale experiment in transparent and opaque paint, separate from the unstretched canvases associated with his mature poured work. The museum record documents the material directly.
LACMA catalogs Pollock’s No. 15, 1950 as oil on Masonite, a manufactured wood-fiber board. This painting shows that his poured and flung marks were not confined to stretched canvas. The rigid panel offers a distinct support within the same period as his large-scale works.
