Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation
From French schiste, Greek skhistos i.e. split

Used in aquariums, Writing Slates
Mica Schists, Calc-Silicate Schists, Graphite Schists, Blueschists, Whiteschists, Greenschists, Hornblende Schist, Talc Schist, Chlorite Schist, Garnet Schist, Glaucophane schist.
Easily splits into thin plates, Smooth to touch
Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

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
Medium Grained Rock, Opaque Rock

As Building Stone, As Facing Stone, Garden Decoration
Building houses or walls, Cement Manufacture, Construction Aggregate, for Road Aggregate, Landscaping, Making natural cement, Raw material for the manufacture of mortar
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.
