Formation
Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.
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 Mugearite and Pumice Properties
Know all about Mugearite and Pumice properties here. All properties of rocks are important as they define the type of rock and its application. Mugearite and Pumice belong to Igneous Rocks.Texture of Mugearite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Pumice is Vesicular. Mugearite appears Dull and Soft and Pumice appears Vesicular. The luster of Mugearite is not available while that of Pumice is earthy. Mugearite 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 Mugearite are 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.
