Black Clay, La Chamba Cookware, is well-known and used throughout Colombia in restaurants and homes for preparing and serving traditional dishes. Its origins can be traced back at least 700 years to vases and pitchers found in pre-Columbian archaeological sites. It is still made in the traditional manner, by families in a small village on the banks of the Magdalena River in Central Colombia. Each piece is hand-made using local area clays, then hand burnished with a stone. The pieces are then fired in the village, giving them the distinctive black color and elegant look.
