Earthcasting is a process developed by the American artist Thomas Sayre. Very large shapes are dug from the earth and filled with concrete mixed with iron oxide, along with structural supports. When the concrete cures, it is pulled up from the earth and permanently set in place. Earthcastings are often monumental in scale, as seen below in a recent installation for the town of Kinston in eastern North Carolina. The process requires a team of collaborators who inevitably influence the resulting sculpture with their own hands.
With these sculptural forms, Sayre seeks to capture the intersection between the forces of human creativity and those of nature. Where the artist pushes, gravity pulls. Where manmade concrete is poured, the earth presses back with a texture, pattern, and color of its own.
A series of images below showcase some of the stages in the earthcasting process using the installation in Kinston as an example.
