Formation
Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high temperature and pressure hence forming Wackestone.
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 Wackestone and Pumice Properties
Know all about Wackestone and Pumice properties here. All properties of rocks are important as they define the type of rock and its application. Wackestone belongs to Sedimentary Rocks while Pumice belongs to Igneous Rocks.Texture of Wackestone is Clastic whereas that of Pumice is Vesicular. Wackestone appears Rough and Dull and Pumice appears Vesicular. The luster of Wackestone is dull while that of Pumice is earthy. Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Pumice is available in beige, grey, light green, light grey, pink, white, yellow- grey colors. The commercial uses of Wackestone are cemetery markers, pottery 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.
