Definition
Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Pumice and Talc carbonate Properties
Know all about Pumice and Talc carbonate properties here. All properties of rocks are important as they define the type of rock and its application. Pumice belongs to Igneous Rocks while Talc carbonate belongs to Metamorphic Rocks.Texture of Pumice is Vesicular whereas that of Talc carbonate is Very Soft. Pumice appears Vesicular and Talc carbonate appears Soft. The luster of Pumice is earthy while that of Talc carbonate is pearly. Pumice and Talc carbonate are available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey 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 Talc carbonate are manufacturing of baby powder.
