Up for consideration is this Mosser Aqua Uranium or Manganese (not sure see the photo) Glow Glass Salt & Pepper Shaker Set features a unique Eye Winker Pattern in a colonial style design. Made of opalescent glass with a glossy finish, these shakers are a set of 2 square-shaped containers in a beautiful blue color. Produced in the United States by Mosser, these 4-inch tall shakers add a decorative touch to any dining table with their original design and eye-catching glow. Please see all the photos as this was tested under the black light and it does glow like uranium glass. Feel free to message with any questions and thank you for taking the time to look.
