Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
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.

All about Evaporite and Comendite Properties
Know all about Evaporite and Comendite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Comendite belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Comendite is Porphyritic. Evaporite appears Glassy, Vesicular and Foilated and Comendite appears Foliated. The luster of Evaporite is subvitreous to dull while that of Comendite is dull. Evaporite is available in colourless, green, grey, silver, white colors whereas Comendite is available in blue, bluish - grey colors. The commercial uses of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite and that of Comendite are cemetery markers.
