Definition
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.
Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals

Archaeological Significance
Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

All about Serpentinite and Pumice Properties
Know all about Serpentinite and Pumice properties here. All properties of rocks are important as they define the type of rock and its application. Serpentinite belongs to Metamorphic Rocks while Pumice belongs to Igneous Rocks.Texture of Serpentinite is Earthy whereas that of Pumice is Vesicular. Serpentinite appears Rough and Dull and Pumice appears Vesicular. The luster of Serpentinite is waxy and dull while that of Pumice is earthy. Serpentinite is available in black, brown, green, grey, white colors whereas Pumice is available in beige, grey, light green, light grey, pink, white, yellow- grey colors. The commercial uses of Serpentinite are commemorative tablets, creating artwork and that 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.
