Why did Jackson Pollock attend David Alfaro Siqueiros’s experimental workshop?

Jackson Pollock attended the experimental workshop of the Mexican Social Realist muralist David Alfaro Siqueiros in New York to explore new techniques and materials.1

During his time at the workshop, Pollock began experimenting with enamel paint. This experience was significant to his artistic development, as he later adopted the use of commercial enamel house paint in his own work, noting that it provided him with greater fluidity than traditional artist paints. This period of experimentation contributed to the evolution of his practice, eventually leading to the development of his signature "drip and splash" method.1
