About Slate
As a Commodity:
i. A fine-grained rock displaying strong slaty cleavage and hence can be split into slabs and thin plates. Most slate was formed from shale, or fine grained tuffaceous rocks during low grade regional metamorphism. Usually gray to black, sometimes green, yellow, brown, or red. Slates are composed mostly of quartz, micas and chlorite, with minor hematite, clays, and other minerals.

ii. A coal miner's term for any shale accompanying coal; also, sometimes the equivalent of bone coal.
