Pair of Antique Needle Etch glass cordial or apperitif stems

This is a nice pair of needle-etched thin-walled blown glass stem cordials. The pattern features abstract sunflowers and ribbons. They are a bit over 3.5 inches tall and probably date to the 1920s when the needle etch technique was most widely used. Needle etched glass was an acid etching technique applied to thin glass. In the needle etching process, a glass blank was coated with wax. A skilled setter used a complex machine to carve a repeating pattern in the glass. The glass was set in place and slowly rotated while the machines needle traced the pattern into the wax. Once the pattern was complete, a second worker repaired any spots where the wax coating had been damaged by handling. Then the piece was placed in an acid dip to create the pattern.

This pair is in good shape with no chips, cracks, or repairs. One stem has a few bits of debris inside the glass of the foot, but overall they look nice and have good workmanship.
