Privy digging is directly linked to antique bottle collecting. Glass or clay bottles are the most likely items to be found in an average 19th century privy.

When an aluminum or plastic bottle cap has an integral band, it is usually connected by thin bridges. They can be molded along with the cap or slit afterwards.
