This Vintage Fire King Vitrock Tulip Uranium Milk Glass SALT Shaker from the 1940s is a rare and collectible piece made in the United States by Anchor Hocking. The shaker features a beautiful tulip pattern in white milk glass with a glossy finish, and it glows slightly under black light due to its uranium content - while it glows as compared to regular milk glass (see last picture), its uranium content must be a bit less than others we've seen that glow more brightly. With a retro style and a lid included, this original piece is a unique addition to any vintage collection of decorative cookware and serveware. Very nice collectible!
