This bonbon dish is made of uranium glass and glows beautifully under uv light. It is in excellent condition with no chips or cracks. There are a few air bubbles on the bottom of the dish as shown in pictures. Pre stamp so an early piece. Hand blown into mold a between the years of 1941-1943 or 1959-1972. A wonderful collection piece for the uranium glass collection, or as a stand alone decor piece.
