Formation
Foidolites is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. 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 Foidolite and Pumice Properties
Know all about Foidolite and Pumice properties here. All properties of rocks are important as they define the type of rock and its application. Foidolite and Pumice belong to Igneous Rocks.Texture of Foidolite is Earthy whereas that of Pumice is Vesicular. Foidolite appears Dull and Pumice appears Vesicular. The luster of Foidolite is subvitreous to dull while that of Pumice is earthy. Foidolite is available in black, brown, colourless, green, grey, pink, white colors whereas Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. The commercial uses of Foidolite are cemetery markers, 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.
