Slate in Interior and exterior Design
It is a beautiful stone with many applications. Increasingly it is being used in areas where more often other stones were used. Bathrooms using slate as a bath capping, vanity top and tiled walls and floors adds a sleek modern feel. Fire hearths and slips are made using slate traditionally and are the finishing touch to your fireplace. Slate has a matt look that comes in smooth and riven finishes.
Origin of Slate
Slate is a fine-grained, foliated metamorphic rock that is created by the alteration of shale or mudstone by low-grade regional metamorphism. Slate is composed mainly of clay minerals or micas depending upon the degree of metamorphism to which it has been subjected. The original clay minerals in shale alter to micas with increasing levels of heat and pressure. Slate can also contain abundant quartz and small amounts of feldspar, calcite, pyrite, hematite and other minerals.
Use of Slate
It is popular for a wide variety of uses such as landscaping, flooring, fireplaces and hearths because of its durability and attractive appearance.
Because it is a good electrical insulator and fireproof, it was used to construct early-20th-century electric switchboards and relay controls for large electric motors. Fine slate can also be used as a whetstone to hone knives.
