If anyone could point me to a video or link a video of anyone melting iron oxide in a cast to create iron oxide bars, I would like to see how brittle the product would be. I searched online but could find no one who melted iron oxide. It seems everyone stops at Iron (III) Oxide powder after the initial reaction of oxygen with iron. But what happens after the reaction if you melt Iron (III) Oxide. Will it adhere together? How strong would the material be?
