Formation
Benmoreite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
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 Benmoreite and Pumice Properties
Know all about Benmoreite and Pumice properties here. All properties of rocks are important as they define the type of rock and its application. Benmoreite and Pumice belong to Igneous Rocks.Texture of Benmoreite is Glassy, Massive, Porphyritic, Scoriaceous, Trachytic, Vesicular whereas that of Pumice is Vesicular. Benmoreite appears Rough and Dull and Pumice appears Vesicular. The luster of Benmoreite and Pumice is earthy. Benmoreite is available in black, brown, light to dark grey colors whereas Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. The commercial uses of Benmoreite are commemorative tablets, creating artwork, curling 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.
