Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). These iron ores have been mined to produce almost every iron and ...

Absolutely beautiful finish on that copper part! PS - I did a slight amount of machining on copper while a grad student many years ago, mainly drilling small diameter holes. On the advice of our machine shop folks, I used "lard oil." Without it, the drill bits would load up, and usually break. I'm just not sure how/where you'd get lard oil cheaply.

By 500 B.C., men used bronze axes, saws and chisels to mill rough lumber for wood homes and forts. And, in 375 A.D., the Romans built a waterwheel-powered sawmill that revolutionized the construction and furniture making industries. The Romans used a reciprocating blade that cut wood in an inefficient back-and-forth motion, much like hand-sawing.
