VTG Fenton Glass Colonial Orange Double Crimped Footed Pedestal Bowl cadmium

vintage Amberina glass pedestal bowl, also known as a compote or candy dish. This type of glassware is known for its distinctive color gradient, shading from red at the top to amber or yellow at the base. This specific piece appears to be in a "fine cut & block" or "thumbprint" pattern, often associated with manufacturers like Fenton or L.E. Smith. Amberina glass was originally patented in 1883 by the New England Glass Company and was popular during the mid-century period, with production continuing by various companies over the years. The ruffled or scalloped edge is a common design feature for this style of bowl. authentic amberina glass glows under a blacklight. The glow is caused by cadmium, which is a component in the glass that fluoresces with a yellow or orange color under UV light. The yellow parts of the glass contain cadmium, while the red is created by heating the glass to "strike" the red color with selenium, which can cause the fluorescence to vanish in the red areas What causes the glow: The yellow to orange glow is a result of cadmium in the glass. Why the red doesn't always glow: The red color is created by reheating the glass after it's formed. This reheating process can make the fluorescence from the cadmium disappear in the red areas. Modern reproductions: Some modern reproductions of amberina may not contain cadmium and therefore will not glow.
