Bone in vinegar (Baby blue dragon bone)

Bone in vinegar is an item used during the Rag and Bone Man wish list. It is made by using the baby blue dragon bone 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 baby blue dragon bone after 12 seconds.

Emptying the pot will return an empty pot, but destroy the baby blue dragon bone.
