[Aztlan] Aztlan Digest, Vol 26, Issue 28 Iron Ore

[Benjamin Carter]

Rod,

I am not well versed in the difference between ochre and hematite, but 
as far as I can tell, hematite is a general term that includes many 
different variations on a rhombohedal form of Iron (III) oxide. The 
variations include the metalic-looking varieties, but can also be 
"ochre", which really (especially coloquially) seems to be a catchall 
term for red iron oxides. Any one else out there that can correct me?

It is the hydrated ores of iron, Limonite, that produces the ocher color.  Hematite can also take a fine polish and was used for mirrors   (as in Tezcatlipocas) and other decorative items.  It can also be an ore of the metal but the temperatures required were probably beyond  Amerindian capabilities.
