Book of Mormon Evidence: Olmec Iron

Abstract
The Book of Mormon describes the Jaredites digging iron ore out of the ground and working it (ca. 1100 BC). Archaeology has shown that during the same general time period, the Olmec civilization was digging iron ore out of the ground, transporting it, and shaping it in specialized workshops.Ether 10:23 describes Jaredite metal working ca. 1100 BC. No blast furnaces or smelting operations are mentioned in the text. It appears that, at this time, the Jaredites simply dug naturally-occurring high-grade ores right “out of the earth” and worked the ores as lumps of material to fashion useful objects. One of the metallic ores they dug up and worked was iron.
High grade meteoric iron (iron from fallen meteors) is rare, but other high-grade iron ores such as hematite, magnetite, and ilmenite are more abundant and are mined commercially today. It is widely-known among archaeologists that the Olmec fashioned polished concave iron mirrors out of naturally-occurring hematite, magnetite, and ilmenite.1
Both of the mirrors displayed above are dated prior to 400 BC, the traditional date of the Olmec collapse. A particularly impressive Olmec piece is now in the Wadsworth Atheneum Museum of Art in Hartford, CT. It is a figurine of a seated dwarf fashioned from a single lump of highly polished hematite iron-ore.
Shops that worked another form of iron ore (ilmenite, a principal source of modern titanium) at an industrial scale have been discovered at three sites in southern Mesoamerica: San Lorenzo in Veracruz, and Mirador Plumajillo and Amatal, both in Chiapas. The ilmenite ore these workshops processed was imported from igneous sources in Oaxaca and Chiapas.
San Lorenzo was the first Olmec capital. Ann Cyphers Guillén found 8 tons of polished, perforated ilmenite iron-ore beads at a workshop in the SE sector of the San Lorenzo plateau. The workshop dated to ca. 1100 BC.2
The perforations were made with a drill, likely using fine sand as an abrasive. Several of the San Lorenzo artifacts were analyzed by physicists and geologists.3 The iron-ore pieces could have been used as jewelry, chain mail armor, or miniature tools when hafted with a small wooden handle. Beads average 3 centimeters in length. They are very similar in form to decorative jade beads found throughout Mesoamerica.
