This is an early 20th century antique kerosene glass jug with thick wavy glass. This jar originally fit onto a stove and held kerosene fuel. When the bottle was turned upside down on the stove oil entry spot it would dispense the Kerosene fuel. The top has a small pressure spigot and unscrews. There is a metal band and bail handle for transporting. The clear glass top and small opening make it ideal for a small scale terrarium. It would make a great primitive display piece. It is vintage and shows wear but looks great. It measures about 7 1/4″ wide and about 9″ tall.
