Most recently, the duo has been experimenting with Chamba pottery, made from a type of black clay uniquely found in the small town of La Chamba, some three-and-a-half-hours southwest of Bogotá. The clay is fired at high temperatures to turn black or red, and then polished with an agate stone. The Chamba vases above are a modern take on the poporo—traditional vessels used to hold lime, used when chewing coca leaves—and are modular, able to grow with a simple change of hardware.
