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.

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Pumice and Limestone Properties

Know all about Pumice and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Pumice belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Pumice is Vesicular whereas that of Limestone is Clastic or Non-Clastic. Pumice appears Vesicular and Limestone appears Rough and Banded. The luster of Pumice is earthy while that of Limestone is dull to pearly. Pumice is available in beige, grey, light green, light grey, pink, white, yellow- grey colors whereas Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow 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 Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper.
