Fenton Glass Markings

Q: What marking should be on the bottom to identify something as Fenton glass? I have seen a few different markings on items on eBay.

A: Fenton was founded in 1905 in Martins Ferry, Ohio. The company is known for its carnival glass made between 1907 and 1920. Most Fenton glass is marked “Fenton,” but some other marks were also used. Pieces marked with “F” in an oval were made from molds bought from other glass companies. Pieces marked with the three letters “O,” “V,” and “G” are part of Fenton’s Olde Virginia Glass line, made from 1960 to 1979. Fenton stopped making art glass in 2011. Copies of Fenton items are currently being made by an unrelated company, Fenton’s Collectibles, using original Fenton molds. The copies are marked with both the Fenton mark and Fenton’s Collectibles mark.
