Si Satchanalai / Sawankhalok :
The Si Satchanalai kilns on the river Yom in north-central Thailand are to the north of the town of Sawankhalok. When I started studying oriental ceramics Sawankhalok was the name used to describe the high-fired stoneware that is now known to have come from Si Satchanalai. This kiln site is north of the other large Thai ceramics production center of Sukhothai. Both centers of production were under the cultural direction of the Sukhothai kingdom. Archaeological evidence supports a production period starting as early as the 14th century and coming to an end in the 16th century. Export ware as well as domestic wares and architectural ceramics were made of high-fired stoneware with decoration in iron-oxide, monochrome brown or celadon glazes.
