A bright orange, 39 cm diameter, platter that shows a significant degree of radioactivity due to uranium salts used in the glaze. These salts produced brilliant colours in the glazes. This particular platter does not have a symbol indicating the manufacturer but similar platters known as “Fiesta-ware” appeared on the market especially before 1944. At that point uranium became treated as a strategic material and disappeared from the consumer market, although some glazes were manufactured in the 1960s with depleted uranium. An article about activity measurements from a similar platter was published in AECL’s Chalk Talk in July 1981 (Volume 3 No 7).
