Information about Pumice

Rocks are naturally occurring solids which are composed of minerals & have been used by humans since ages. From Stone Age, rocks are used for various purposes. Also, the metals and minerals found in rock play an important role in our life. Get to know all the Pumice Uses. We have provided you with all information about Pumice rock here. Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pumice is white, greenish white or grey. Get to know more about Pumice rock and characteristics of Pumice rock in the next sections.

Characteristics of Pumice

Many rocks have distinct characteristics. Some of the Properties of Pumice are hardness, structure, streak, fracture etc. Pumice is significant as it is composed of minerals and has variety of uses in our day to day life. The characteristics of Pumice plays an important role in its identification. The hardness of Pumice is 6 on Mohโ€™s hardness scale. Rocks according to their hardness are divided into:Types of Hard Rocks, Types of Soft Rocks and Rocks with Medium Hardness. Fracture of Pumice rock is planar. Its specific heat capacity is 0.87 kJ/Kg K. Pumice is impact resistant, pressure resistant. Some of its uses are:

  • Interior Uses: Decorative aggregates, Flooring, Homes and Interior decoration.
  • Construction Industry: As dimension stone, Cement manufacture, For road aggregate, In landscaping and horticulture, Making natural cement, Production of lightweight concrete blocks.

More About Pumice

Pumice is a type of Igneous Rocks. The color of rock is one of its important property. Pumice rock is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. It is Vesicular in appearance. The Pumice mineral content includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica. Its compound content includes Al, Aluminium Oxide, CaO, Carbon Dioxide, MgO, Silicon Dioxide. Letโ€™s move on to the types of Pumice. The types of Pumice include Scoria. Fossils are the remains of prehistoric plants or animals which are embedded in rock and preserved in petrified form. Fossils are found only in sedimentary rocks. As Pumice belongs to Igneous Rocks, fossils are not found in it.
