St Uze water butter dish

Antique St. Uze butter dish with a cobalt blue floral design. This water-cooled butter dish is an ingenious system that allows butter to be kept at room temperature without going rancid. The upper, bell-shaped container holds the packed butter, and cold water is placed in the lower part. The water forms a natural airtight barrier. In perfect condition. Use as a butter dish or as a decorative piece.
