Bone in vinegar (Dagannoth ribs)

Bone in vinegar is an item used during the Rag and Bone Man wish list. It is made by using the dagannoth ribs with a pot of vinegar. The bone in vinegar should be brought along with logs to the pot boiler near the Odd Old Man. The pot boiler should be lit with the logs, which will result in a polished dagannoth ribs after 12 seconds.

Emptying the pot will return an empty pot, but destroy the dagannoth ribs.
