Comendite is a hard, peralkaline igneous rock, a type of light blue grey rhyolite
Comendite derives its name from the area of Le Commende on San Pietro Island in Italy

Very fine grained rock, It is One of the Oldest, Strongest and Hardest Rock
Comendite is a type of Igneous rock which is formed due to cooling and solidification of lava or magma. It may form with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Easily splits into thin plates, It is One of the Oldest, Strongest and Hardest Rock
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
