Large jugs are most commonly found grave goods. The decoration is a balance between geometric designs of natural elements or designs of animals. Vegetation and human figures were rarely depicted on pottery designs at Sialk. The representation of a bird is considered to be associated with funerary rituals as it is commonly shown on libation vases. Rams are also typically found on Sialk pottery and can be identified by the exaggerated emphasis and curvature of the horns. The skill of the pottery is shown through the delicate shapes and forms as well as the elaborate designs that make Sialk pottery so unique. Most of the artifacts from Sialk are now in the Louvre Museum in Paris and the Tehran Museum in Iran.
