Clay minerals

RAW CLAY a stiff, sticky fine-grained earth, typically yellow, red, or bluish-gray in color and often forming an impermeable layer in the soil. It can be molded when wet, and is dried and baked to make bricks, pottery, and ceramics

Sedimentary, Igneous and Metamorphic rocks Sedimentary rocks Sedimentary rocks are those which are formed by the deposition and lithification of sediments. These are divided into three basic types. 1) clastic sedimentary rocks are those derived from mechanical weathering such as shale, sandstone, breccia and conglomerate. 2) sedimentary rocks derived from precipitation of a solution such as salts and limestone dissolved in water. 3) rocks derived from plants and animals such as coal and some…

What is Marble? Marble is a metamorphic rock which is non foliated and is formed when limestone is subjected to heat and pressure where calcite recrystallises to form a rock that is a mass of interlocking calcite crystals. In marble not all of the rock is formed of calcite other minerals can also be present such as clay minerals, micas, quartz, pyrite, iron oxides and graphite. Same as of the limestone marble, dolostone when metamorphose produces dolomitic marble. How does marble forms?…

With an atomic number of three, Lithium is the third lightest element on the periodic table and the lightest solid at room temperature and pressure. For almost two centuries after its discovery, Lithium didn’t have much in the way of practical uses. However, in the last few decades, its status changed, and it went from one of the least useful elements to one of the most important to the world’s economy. Lithium is also the source of one of the biggest unexplained problems in physics.

White Howlite is the great Gemstone that looks like white and known for being artificially Gemstones. It can be spotted in distinct hues to view like semi-valuable gems such as Turquoisae and Coral, Lapis Lazuli. These are very popular across the world. White Howlite is very beneficial to the wearers and it affects people in many good manners. - Bulk Gemstones

Limestone is a sedimentary rock primarily composed of calcium carbonate (CaCO3) in the form of the mineral calcite. It often forms in clear, warm, shallow marine waters through two main processes: the accumulation of carbonate
