The first ceramic vestiges of the Diaguitas were found at Las Animas creek in the Elqui Valley (IV Region), and correspond to the archaic period. The dishes from this stage are quite deep with thick walls and shaped like a half of an orange (semi-globular). The utensils were decorated with thick lines forming concentric circles, both in its interior and exterior.
Towards the end of the transition period, the Diaguitas began to innovate in the decoration of their pottery, new forms were incorporated: hooks, triangles and escalating traces, characteristic pre-Columbian decoration.
During the classical period, the so-called duck vessels and some ornamental chalice appeared. Most of these ceramics had vertical walls, inclined outwards, inwards or perpendicular. Drawings decorate the external part of the vessel, while the interior was red tinted. Geometric decorations became more common.
The so-called duck vessels along with caskets and anthropomorphous ceramic are the most outstanding work of the Diaguita culture.
