Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

All about Evaporite and Claystone Properties
Know all about Evaporite and Claystone properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite and Claystone belong to Sedimentary Rocks.Texture of Evaporite is Earthy whereas that of Claystone is Clastic. Evaporite appears Glassy, Vesicular and Foilated and Claystone appears Rough and Dull. The luster of Evaporite is subvitreous to dull while that of Claystone is dull. Evaporite is available in colourless, green, grey, silver, white colors whereas Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow 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 Claystone are pottery.
