Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

All about Evaporite and Scoria Properties
Know all about Evaporite and Scoria properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Scoria belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Scoria is Vesicular. Evaporite appears Glassy, Vesicular and Foilated and Scoria appears Glassy and Vesicular. The luster of Evaporite and Scoria is subvitreous to dull. Evaporite is available in colourless, green, grey, silver, white colors whereas Scoria is available in black, brown, dark grey to black, red 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 Scoria are as a traction material on snow-covered roads, creating artwork, high-temperature insulation, in gas barbecue grills.
