A major figure in the abstract expressionist movement, Pollock was widely noticed for his "drip technique" of pouring or splashing liquid household paint onto a horizontal surface, enabling him to view and paint his canvases from all angles. The work of Thomas Hart Benton, Pablo Picasso and Joan Miró influenced Pollock. Pollock started using synthetic resin-based paints called alkyd enamels, which at that time was a novel medium. Pollock described this use of household paints, instead of artist's paints, as "a natural growth out of a need".He used hardened brushes, sticks, and even basting syringes as paint applicators. Pollock's technique of pouring and dripping paint is thought to be one of the origins of the term action painting. With this technique, Pollock was able to achieve his own signature style palimpsest paintings, with paints flowing from his chosen tool onto the canvas. By defying the convention of painting on an upright surface, he added a new dimension by being able to view and apply paint to his canvases from all directions.In 1936, Pollock participated in an experimental workshop run by the Mexican muralist David Alfaro Siqueiros. It was there that he first used liquid enamel paints, which he continued to incorporate in his paintings in the early to mid 1940s, long before he encountered the work of the Ukrainian American artist Janet Sobel (1894–1968) (born Jennie Lechovsky). Peggy Guggenheim included Sobel's work in her The Art of This Century Gallery in 1945.Jackson Pollock and art critic Clement Greenberg saw Sobel's work there in 1946 and later Greenberg noted that Sobel was "a direct influence on Jackson Pollock's drip painting technique". In his essay "American-Type Painting", Greenberg noted those works were the first of all-over painting he had seen, and said, "Pollock admitted that these pictures had made an impression on him"
