All about Scoria and Evaporite Properties

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