Calcium oxide is usually made by the thermal decomposition of materials, such as limestone or seashells, that contain calcium carbonate (CaCO 3; mineral calcite) in a lime kiln. This is accomplished by heating the material to above 825 °C (1,517 °F), [ 6 ] [ 7 ] a process called calcination or lime-burning , to liberate a molecule of carbon ...
In the lime industry, limestone is a general term for rocks that contain 80% or more of calcium or magnesium carbonate, including marble, chalk, oolite, and marl.Further classification is done by composition as high calcium, argillaceous (clayey), silicious, conglomerate, magnesian, dolomite, and other limestones.

Lime does reduce the odor of decomposition, but it also reduces the rate of decomposition. As a result, a lime-covered body may be less likely to get sniffed out, but it's more likely to linger.)" (not my emphasis.)
If the decrepitation begins at a temperature less than the temperature required to form the mineral, it is likely that the rate of decrepitation will speed up once the temperature exceeds that of the initial heating. [citation needed] For metamorphic rocks, there are certain principles for measuring the decrepitations. What is known as D1 ...
The amount of moisture in the environment in which a corpse decomposes also has an effect on the rate of decomposition. [11] Humid environments will speed up the rate of decomposition and will influence adipocere formation. [11] In contrast, more arid environments will see corpses dry up faster and decompose more slowly. [11]
Why do people throw lime on dead bodies? In some sources it is explained that lime prevents decay and the spread of infection, elsewhere it's stated that lime assists with decomposition.

The theoretical heat (the standard enthalpy) of reaction required to make high-calcium lime is around 3.15 MJ per kg of lime, so the batch kilns were only around 20% efficient. The key to development in efficiency was the invention of continuous kilns, avoiding the wasteful heat-up and cool-down cycles of the batch kilns.
Decomposition in animals is a process that begins immediately after death and involves the destruction of soft tissue, leaving behind skeletonized remains. The chemical process of decomposition is complex and involves the breakdown of soft tissue, as the body passes through the sequential stages of decomposition . [ 2 ]
