How Is Limestone Made? - Reference
Limestone can be formed as a result of evaporation, as is the case for stalactites and stalagmites in caves, or through the accumulation of calcium carbonate in marine environments. Limestone is either a biological or a chemical sedimentary rock, depending on its method of formation.

Limestone is formed from the cementing and compacting of sediments. It is a sedimentary rock. Limestone is a type of sedimentary rocks which is composed of calcite and CaCO 3. It may be formed inorganically or by the biochemical processes. There are different types of limestone because of variety of conditions under which it is produced.

Sandstone is formed from layers of sandy sediment that is compacted and lithified. Chemical sedimentary rocks can be found in many places, from the ocean to deserts to caves. For instance, most limestone forms at the bottom of the ocean from the precipitation of calcium carbonate and the remains of marine animals with shells. If limestone is ...

How Is Gneiss Formed? - Reference
Gneiss is formed from the high-temperature metamorphism of existing igneous rocks, generally granite or diorite. The rocks that form gneiss are exposed to extreme pressures and temperatures of between 600 and 700 degrees Celsius. These temperatures cause the individual minerals to migrate, forming distinct bands through the rock.

Limestone also helps to improve the handling and formability of the molten glass. In a pure silica melt, viscosity is high and this (alongside with high temperature) makes the glass difficult to shape, especially when it needs to hold a form, for example, in the production of glass containers. Limestone reduces the viscosity, making the liquid ...

Limestone's chemical name is calcium carbonate, and its formula is CaCO3. What is the source of most calcium carbonate in limestone deposits? Most limestone, CaCO3, comes from the shells of dead marine organisms like corals. As the organisms die their shells build up layer by layer to form the limestone deposit.
