What is slate
Slate stone (in other words, limestone) is a sedimentary rock of volcanic origin, consisting of clay minerals, which is characterized by a wide variety of colors and reliefs. It is formed during the compaction and crystallization of clays at great depths.
The color of the stone depends on the presence of minerals and impurities of various chemicals in it. The most commonly found limestone in nature is golden, yellow, brown, purple, gray, green and black.
Slate differs from other stones in its layered structure, which allows it to split easilyinto thin layers and plates. Often large blocks and slabs are used in their natural form.

• Siliceous limestone. This granular rock is formed in the form of thin slabs or sheets of crystalline quartz formations. Minerals, depending on the environment of origin and the amount of impurities, can be gray, green, red, purple and black. Sometimes this type of slate stone is used instead of flint.
• Mica flagstone. It is composed of mica quartz and is found in white, brown and black colors.
