Invented in the 1860s, the glass target ball was a popular aerial gunnery target, being light enough for easy launching and coming apart quite impressively when struck. Though displaced for general use by the invention of the clay pigeon, the glass ball held a niche with exhibition shooters, sometimes being loaded with feathers or similar filler to make the breaks even more eye catching. While produced in quantity, as a consumable asset literally made to be broken, few have made it to the present day in one piece. All ten were constructed using 3-piece molds, with roughly cut open necks and the usual small air bubbles. Six are brown amber colored, with one light blue and three cobalt blue. One amber ball has a pattern of four dots near the neck, one cobalt ball has five dots, and the light blue ball has three dots opposite a small triangle.

Fine overall, with some minor chipping around the necks.
