Rare Vintage Tiffin Modern Twillight Neodymium Optic Glass Vase

Sale is for one vase. No chips or cracks no etching inside. This is a special glass that is difficult to work with. Blenko attempted it and broke their kiln. Some people call this alexandrite glass like the color changing gem. This glass changes color in light. It goes from purple to pink to blue depending on the light. It is hard to show how beautiful this color is because it's not too thick except the footed part but I have collected glass for around 30 years (starting with depression glass) and this is one of my very favorite glass colors. Production of this glass was from the 50s-60s.
