What is slate?
Slate stone (in other words, flagstone) 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 in the process of 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. Most often found in nature is the flagstone of golden, yellow, brown, purple, gray, green and black.
Slate differs from other stones in a layered structure, which allows it to easily split into thin layers and plates. Often large blocks and slabs are used in their natural form.

• Siliceous flagstone. This granular rock is formed in the form of thin plates 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 stone slate of this type is used instead of flint.
• Mica flagstone. It consists of quartz mica and is found in white, brown and black colors.
