Light calcium carbonate, also known as precipitated calcium carbonate, is calcined limestone and other raw materials to produce lime (the main component is calcium oxide) and carbon dioxide, and then water is added to digest lime to produce lime milk (the main component is calcium hydroxide), a...

or even minerals precipitated from water. These rocks typically form in layers (strata), often in environments like riverbeds, lakes, and oceans. Sedimentary rocks are characterized by their grain size, composition, and the processes that formed them...
The rocks we used for this crystal-growing experience aremagnesium-rich dolomite.Dolomite is an evaporative sedimentary rock that’s made up of sediments and minerals. This unique variety of dolomite, found in an ancient lagoon that was surrounded by a coral reef millions of years ago, will gro...
More than 10% of the global human population is now afflicted with kidney stones, which are commonly associated with other significant health problems including diabetes, hypertension and obesity. Nearly 70% of these stones are primarily composed of calcium oxalate, a mineral previously assumed to b...
