Bought a weird ceramic jar at a spring estate sale. It has a lid with a finger sized hole in the center and hand painted flowers. No smells, completely empty inside. Anyone know what this thing is?

It was completely empty, with no discernible scent or residue inside. This piqued my curiosity and led me on a journey to uncover the origins and purpose of this mysterious vessel. Could this be a forgotten relic of a bygone era, or perhaps a simple household item with an unexpected history?

The ceramic jar stands approximately 5 inches tall and 4 inches in diameter. Its smooth, glossy surface is decorated with delicate hand-painted florals that suggest it was crafted with care
