Question : I need a detailed stage by stage, week by week analysis.
Answer : As far as a specific timeline goes, this is just too variable to even begin to answer definitively. Factors like state of the body before burrial, climate, temperature, soil type, organisms, type of casket and/or vault, body composition, quality of embalming all play a role in the rate of decomposition. A properly embalmed body in a casket and vault can actually become mummified in the right conditions (or take decades-centuries to decompose), OR it can take a little as a year when done improperly and in the worst conditions. In most cases of embalmed bodies, the nearest average answer is that it takes decades to decompose to bone. Even though embalmed and sealed, the environment is still not sterile, and any microorganisms can reproduce and begin the process of decay... but this process is significantly slowed with 'proper' burial methods.
Essentially, the decomposition process is the same in the stages it takes, but differs enormously depending on those other factors. If you'd li..
Question : And can I make it any faster?
Answer : the natural decomposition of non-skeletal tissue in the body can take weeks to years. the process can even be delayed exceptionally long by a body held in a substrate of water or buried in a peat bog. heat will increase the rate of decomposition along with the presence of insects that could potentially use the body as a food source
Question : If an average human being dies, how long will it take before the unpreserved corpse begins to decompose, and how long does the proces of decomposing take?
Answer : an average human being start to decompose after 24-48 hours once the ATP supply of the muscles are depleted and the body begings to get rigor mortis. the time of decomposition greatly varies with where the body is lying and in which condition along with physical factors like temperature,humidity etc.
