This is a fabulous and very hard to find collection of WWII (1940’s) vintage USA glass unsilvered glass Christmas ornaments, in red, clear and blue glass with silver tinsel. This is a great addition to any collection! Metallic mercury glass ornaments get their shine from being coated on their interior with a silver nitrate solution. In 1940, WWII wartime shortages restricted this material, and ornaments during this time frame were produced without silvering. Since unsilvered ornaments were less popular than the shiny mercury glass, they are harder to find and thus more collectible. This collection has been in our family since new and stored annually in this vintage Purina egg carton.
