Blackboards are typically made of a type of rock called slate. Slate is a fine-grained metamorphic rock that is easily split into thin, smooth sheets, making it ideal for writing on with chalk.
Slate is fine sedimentary mud that has been subjected to immense pressure over a very long time.
There are three main types of slate rock based on their color and composition: black slate, red slate, and green slate. Black slate is the most common type, formed from shale, while red slate gets its color from iron oxide. Green slate is typically formed from chlorite or other minerals containing green pigments.
Shale can metamorphose into slate, which can metamorphose into phyllite, which can metamorphose into schist, which can metamorphose into gneiss.
Slate typically fractures along flat, thin planes due to its foliated structure, creating smooth surfaces. This type of fracture is known as "conchoidal fracture," which results in thin, sharp fragments when the slate is broken.

Slate is a natural product found in the ground. A type of rock.
The most usual protolith of slate is the sedimentary rock shale.

Slate rock has a fine-grained texture, with individual mineral grains that are too small to be seen with the naked eye. This gives slate a smooth and dense appearance.
A metamorphic rock.

No, but slate and gneiss are both a type of metamorphic rock. Slate will also turn into Gneiss, eventually, if metamorphosing continues. The series is Shale (sedimentary) >> Slate (metamorphic) >> Phyllite >> Schist >> Gneiss
The average weight of slate is approximately 175 pounds per cubic foot. However, this can vary depending on the specific type and density of the slate.
