This is a nice old slip glaze stoneware preserve jar. It would have had a lid and bail handle at one time. There are two small holes on the sides which would have had a wire handle attached to them.
The overall condition is good. There is a small chip on the outer rim and some staining on the unglazed bottom. There are a few dark marks on the outside that did not come off when the jar was washed.
The jar measures approximately 4 ¼” in diameter and 7” high.
