Iron oxide is a quest item used in One Small Favour and One of a Kind. It is obtained by talking to Tindel Marchant in Port Khazard. Marchant requires his stodgy mattress stuffed in exchange for the iron oxide. The oxide must then be taken to Wizard Cromperty in Ardougne in order to complete the next step in the quest. If lost, Marchant will charge 200 coins for a new one.
During One of a Kind, iron oxide is obtained by examining the weapon rack in Robert the Strong's library. After completion of the quest, it can be reobtained from the same spot.
