Formation
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.
Sovites are formed due to low degrees of partial melting of rocks.

All about Pumice and Sovite Properties
Know all about Pumice and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Pumice and Sovite belong to Igneous Rocks.Texture of Pumice is Vesicular whereas that of Sovite is Granular, Poikiloblastic. Pumice appears Vesicular and Sovite appears Dull, Banded and Foilated. The luster of Pumice is earthy while that of Sovite is subvitreous to dull. Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors whereas Sovite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Pumice are as a traction material on snow-covered roads, as an abrasive in pencil erasers, fine abrasive used for polishing, manufacture of soap, solvents, dyes, plastics and fibres, used in aquariums and that of Sovite are an oil and gas reservoir, as a feed additive for livestock, creating artwork, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
