Presented is a very round, skillfully made onion flask, in a pleasing green glass, with a kick up bottom, open iron pontil, and interior folded lip. The glass is very thin and remarkably proportional for a free blown bottle. As expected, there are bubbles and ash in this very early bottle, dating to before 1850, and possibly as old as the late 18th century (Lindsey, Bill. 2010. Bottle Dating. In Historic Glass Bottle Identification & Information Website). Also see other early American examples from major auction houses, constructed in the same manner. The bottle measures 8" tall and the onion bulb measures 4 1/2" in diameter. It is in excellent antique condition with no damage, and glass is nice and clear. This is an excellent, museum grade example for the collector!
