What a fabulous French find. The patination is gloriously heavy and the pot is in amazing condition, with a few chips around the base.
Lovely shape with a deep rim that would have been used for twine to secure the waxed paper cover.
These antique confiture pots are becoming very hard to find as the glass ones replaced them many years ago.
It measures 9cm 3.5" diameter and 7cm, just over 3" tall
