This pair of shakers were manufactured before 1900. Their coloration is an opaque light blue/green . I would say blue milk glass but my wife says they have a green hue . We tried to find the pattern with no success ! They stand 3 & ¼” tall and are about 2” square at the base. We got them without the screw on tops. The tops of the shakers are rough finished ( the way they are supposed to be ). They stand up on the four corners of the square base so I imagine they would be considered footed.
