Antique Ripley & Co. bowl from 1911, measures 10 3/4" in diameter and 4 5/8" in width. The original use was a punch bowl, but the size is more like a salad/ serving / fruit bowl. It glows green under UV light, likely from manganese. Made by Ripley & Co of Connellsville, PA.  One small airhole(???) as shown in picture, otherwise no flaws.
