Vase with Elephant Heads and Cloud Designs China In the eighteenth century, the kilns at Jingdezhen began to make porcelains of a different material. Known as huashi, or "slippery stone," this expensive material, often called soft paste, was used to make thin vessels that frequently were decorated with incised or raised designs under glaze. While the reasons for its introduction remain unclear, it is worth noting that soft paste is easily carvable, and its use would have thus been akin to contemporaneous interests in the manipulation of other materials such as ivory and bamboo. The shape of this vase is loosely based on Bronze Age vessels whose handles were shaped like the heads of animals.. Vase with Elephant Heads and Cloud Designs 51020
