Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.

All about Evaporite and Hawaiite Properties
Know all about Evaporite and Hawaiite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Hawaiite belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Hawaiite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Evaporite appears Glassy, Vesicular and Foilated and Hawaiite appears Dull and Soft. The luster of Evaporite is subvitreous to dull while that of Hawaiite is not available. Evaporite is available in colourless, green, grey, silver, white colors whereas Hawaiite is available in black, brown, light to dark 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 Hawaiite are creating artwork, sea defence.
