Hematite. An important ore of iron, the sesquioxide, so called because of its red color when in the form of powder. It occurs in splendent rhombohedral crystals, and in massive and earthy forms, the last being called red ochre.
“Since the fall, God will not trust us with our own salvation, but it is both purchased and kept by Christ for us, and we for it through faith, wrought by the power of God.”
