By Mary McCarthy, Education Chair, NASGA
Recently at the Santa Cruz Sea Glass and Ocean Art Festival, NASGA Education Chair Mary McCarthy was on hand doing sea glass identification. A woman brought her necklace that included a UV piece with a unique curve. The size of the interior curve provided a clue: it was once a hole!
The source for the piece is a depression era vaseline glass flower frog. Flower frogs, nicknamed because they “sit in water,” feature holes that were used to hold flower stems. Often a two-piece item with a removable lid though sometimes made as one piece, water is placed inside to nourish the flowers. The identified vaseline glass, probably from the 1920s-40s was made with uranium and therefore glows under blacklight.
