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

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