This is a whiteware jar with height of 30 cm. It has a chalk like white body and is covered in a degraded straw glaze. Looking at the glaze the jar is to be dated between 581-906 AD, Sui to early Tang dynasty.
The body is chalk white and absorbs water quickly. Some Tang white clays fire to a pinkish tone. It looks like there was another piece stacked upon this jar during firing. There are three dentation marks on the rim, sometimes referred to as ‘rolled rim’.
