THE SLATE
Slate is a fine-grained metamorphic rock of great structural integrity and beauty. Its nearly perfect natural cleavage allows it to be split into smooth sheets. Slate’s strength, insolubility and imperviousness makes it one of the most durable and versatile materials in the stone industry.

ADVANTAGES AND PRODUCTION
Slate has many advantages.....
Long life and durability.
Resistance to acid and pollutants.
A fireproof building material.
An impermeable barrier to water.
A highly slip resistant material.
The warmth and elegance of a
natural stone.

THE SLATE HISTORY
About 300 to 500 million years ago, slates were layers of black mud on the bottom of shallow seas. As epochs passed, the mud hardened by the process of compaction and cementation. At the same time the sea basins sank, allowing vast amount of new sediments to settle upon the hardening mud.
