The jar is one of the oldest artifacts in the Museum, dating back to the Majiayao - Banshan Culture of the 3rd millennium BC. (Neolithic). It was used as a vessel for the collection of grains. It comes from excavations carried out by the Swedish archaeologist Dr. J. Andersson in 1923 near the Gansu area, in northwestern China. Characterized by a spherical shape with a flat circular base with two handles around the belly, typical of jars, it was made through the use of very fine light-colored clay, enriched by a black mantle decoration, in the upper part of the belly. It has upside-down spiral elements, with respect to the order of the hours on the clock, and framed in the upper part by two important lines, and in the lower part by a horizontal line and a festooned line.
