What is slate?
A slate originates as a sediment usually a fine grained mudstone. Through the action of burial, compression and heat a mudstone will develop progressively from a shale, to a slate; to a phyllite; and then with sufficient heat, to a schist and finally a gneiss. The definitive physical characteristic of slate is it's slatey cleavage which enables the material to be split into parallel sheets (i.e. roof slates). A riven slate is the result of having two sets of cleavage intersecting at an angle and creating a wavy cleavage plane. "Riven" in the stone industry refers to a finish of a stone that has been split along a natural weakness. Certain English green slates originated as volcanic ash deposits that were deposited in water. The stone itself does not have a well developed cleavage and is generally massivev.

Slate characteristics vary with source. Domestic is typically black, green or mottled (Pennsylvania) and is relatively dense. Many imported slates are available today with wide ranging physical characteristics and overall suitability.
