The first pieces of Steuben's Bubbly were made using spiked molds. "When molten glass was rolled over the slab, the spikes left marks in the hot glass. A second applied layer of glass locked in the air, so that the controlled designs could be achieved," according to The Collector’s Encyclopedia of American Art Glass by John A. Shuman III (now out of print but available through online booksellers.) The result was a fairly consistent pattern of bubbles throughout the glass.
Random air bubbles in some Bubbly pieces were created by introducing a willow branch into the glass while hot and removing it immediately. Gasses released from the green wood would enable the glass artisans to work the bubbles. This method also eliminated green and pink tinges that might occur in colorless glass, according to Shuman.
All the objects commonly made by Steuben were fashioned of this type of glass, including vases, bowls, perfume bottles, and candlesticks. Colors used were clear, Antique Green, Bristol Yellow, Wisteria, Topaz, French Blue, and Pomona Green. Some pieces also had a threading design added for interest. The threading could be in the same color as the base piece, or in a contrasting color like the green threading on clear glass shown above (click on the photo for a larger view).
Not all Bubbly pieces are found marked. Some have etched markings on the bottoms, while others have paper labels still attached. Some of those have the pattern name written in the center of the sticker.
