A powder horn, which typically was made of cow or buffalo horn, refers to any personal container that was used for gunpowder. This flask is made of wood, but shaped to resemble a nautilus shell. The floral decoration that makes up the body is inlaid with horn, mother of pearl, and ivory. The two silver hooks would have attached to a strap worn over the shoulder, allowing the user to easily access the gunpowder by lifting the lid off the top.
