How do you identify cranberry glass?

To identify cranberry glass, first examine it under natural light. Most pieces will be a lighter pink color at the top and a darker burgundy hue at the bottom. Next, flip the item over and look for a raised area in the middle. Called a pontil mark, this feature indicates that a piece was mouth-blown, which all cranberry glass was. Hallmarks may also provide clues. Pilgrim was a major manufacturer of cranberry glass and marked some pieces with a capital “P” logo. Another maker, Fenton, used both its name and a script “F” initial as markings. If you're still uncertain whether your piece is cranberry glass, a certified appraiser or knowledgeable antique dealer can give you their expert opinion.
