SSQ Riverstone Slate - Keith Builders Merchants Scotland

Riverstone is technically a phyllite. And if you like slate, then you will LOVE phyllite.

“Phyllite” slate marks a culmination:  It is what happens when the geological forces that form slate are permitted to continue.  With each step — from sediment to shale, from shale to slate and from slate to phyllite slate — the stone becomes harder, denser and stronger.

Phyllites have what is known as a “phyllitic sheen”.  This is a satin-like luster that helps to distinguish phyllite from slate in the field.

It is medium grey in colour, with the slightest hint of green, and has a slightly coarser grain than slate.

Commercially accessible phyllite roofing slate is rare — there are only a handful of sourced known worldwide, and even fewer that are able to split at the thickness required, to be suitable for use as a roof covering material.
