Blue salt shaker: Portieux. Transparent blue glass salt shaker with 2 compartments for salt and pepper. The salt shakers are round decorated with a grid and mounted on a pedestal. In the center, an acorn-shaped handle. Without signature, but it is a Portieux production. Good condition. Dimensions: 12.5 cm by 5.5 cm. Height: 7 cm. Very nice piece to collect or to offer.
