The Ghanian sculptor El Anatsui (CRF 2001) worked with cheap, commonly found objects for decades until he arrived at just the right one: bottle caps. El talks about the transition of working with different materials with his art, and how he “didn’t quite find the freedom of form until [he] started working with bottle caps, which were far lighter, and with which I could create bigger and more versatile sheets. [He] kept discovering new things about the material, and 20 years on it’s still yielding new ideas.” Read more about El’s relationship with the form and the history of it in the Guardian, here.
