Slate is a very dense, but soft and easily scratched material with a low porosity, meaning it will absorb liquids. Slate can be used effectively outdoors as well as indoors although some higher absorbency varieties are unsuitable for exterior areas in freezing climates. Slate is a foliated metamorphic rock derived from shale, consisting mainly of grains of mica and quartz. Most slate is grey to black, but the rock may also feature red or purple depending on its mineral content. The surface of slate is generally uneven with cleft planes that can spall due to the cleaving of the stone along its layers. Slate has a low to medium absorption rate of oils and other liquids. Slate should be sealed with an oil-repellent penetrating sealer to prevent staining and reduce damage. Because of its cleft planes and strong possibility of spalling, slate should not be cleaned at extreme pressures and then only when the grout is in very good condition.
