Oddbean new post about login | logout Iron oxide is just rust. It's not very reactive so I have my doubts but I'm not very knowledgeable on the topic.
True, but there are some other basic oxides that react to form metal glass like lead glass, and there is some research on iron oxide bonding to the surface of silica. Swinging in the dark here but interesting little exploration nonetheless https://www.sciencedirect.com/science/article/abs/pii/S0927775709006591
