If the coffin is sealed in a very wet, heavy clay ground, the body tends to last longer because the air is not getting to the deceased. If the ground is light, dry soil, decomposition is quicker. Generally speaking, a body takes 10 or 15 years to decompose to a skeleton.
For the most part, however, if a non-embalmed body was viewed one year after burial, it would already be significantly decomposed, the soft tissues gone, and only the bones and some other body parts remaining.
Over time, coffins underground will decompose and eventually collapse. Covering the face before closing the casket adds an extra layer of protection and dignity for the deceased's face and can act as a symbolic final goodbye.
If you are looking at a long-lasting ground casket, pick a steel or metal casket. If the grave site is low on water content or moisture, metal caskets are known to last even longer, over five decades. Under favorable weather conditions, experts say that metal caskets may even last more than that – up to 80 years.
After 1 month, the liquefaction process commences. During this stage the body loses the most mass. The muscles, organs and skin are liquefied, with the cadaver's bones, cartilage and hair remaining at the end of this process.
Unless a casket is made of metal and sealed with a material that won't degrade, bugs will eventually get inside.
What's really returned to you is the person's skeleton. Once you burn off all the water, soft tissue, organs, skin, hair, cremation container/casket, etc., what you're left with is bone. When complete, the bones are allowed to cool to a temperature that they can be handled and are placed into a processing machine.
We've witnessed many cremations and never heard a scream. But then again, cremation retorts aren't silent either. Now, bodies do make all kinds of gnarly noises.
Does the body sit up during cremation? Yes, this can happen. Due to the heat and the muscle tissue, the body can move as the body is broken down, although this does happen inside the coffin, so it won't be visible.
The body does not feel pain during cremation because the person is no longer alive. When a person dies, their brain stops sending signals to the body. This means that the person cannot feel pain or any other sensation.
Coffin flies have that name because they are particularly talented at getting into sealed places holding decaying matter, including coffins. Given the opportunity, they will indeed lay their eggs on corpses, thus providing food for their offspring as they develop into maggots and ultimately adult flies.
"The water in the graves seriously affects the coffins already buried. Coffins are not watertight so when the grave fills with water it also fills the coffin, which decomposes and rots the bodies faster.
That seems to come down to what your casket is made of. Rats are prodigious chewers and will bite through anything they can. A wooden casket likely isn't going to keep rats out, at least not over the long term.
By ten-years, given enough moisture, the wet, low-oxygen environment sets off a chemical reaction that will turn the fat in the thighs and bottom to a soap-like substance called grave wax. However, in drier conditions, the body could also be mummified – that's mummification without wrappings, or chemicals.
In a closed casket funeral, the casket remains closed during the viewing and the funeral service. Family members and guests are not able to see the body, and some prefer this option for a variety of reasons.
Do they remove organs when you are embalmed? One of the most common questions people have about embalming is whether or not organs are removed. The answer is no; all of the organs remain in the body during the embalming process.
Open Casket Funeral Etiquette
While some people find comfort in seeing their loved ones as they remember them, it may also be uncomfortable to others. If they have an open casket viewing, make sure you follow proper funeral etiquette: DON'T touch the body under any circumstances.
As mentioned, most of the caskets are not airtight, and advanced decomposition will lead to unpleasant smells even in a closed service. However, it is especially important for funerals with open caskets, as all measures must be taken to ensure that loved ones can say their farewells before decomposition begins.
As mentioned, even embalmed bodies are not spared from natural decomposition, which begins a few days to a week after embalming. For medical purposes and extenuating reasons, bodies can be kept for six months to two years. Bodies that are not embalmed, on the other hand, begin decomposing almost immediately.
The six feet under rule for burial may have come from a plague in London in 1665. The Lord Mayor of London ordered all the “graves shall be at least six-foot deep.” The order never said why six feet. Maybe deep enough to keep animals from digging up corpses.
Undergarments
Next, the undergarments are put on the body. These are supplied by the family, but the funeral director can provide suggestions to ensure they choose something suitable. These are put on first to protect the outer clothing and provide modesty for the deceased.
In Brief. After death, the human body decomposes through four stages. The final, skeleton stage may be reached as quickly as two weeks or as slowly as two years, depending on temperature, humidity and other environmental conditions where the body lies.
The only parts of the body that are removed before cremation are artificial ones like a medical device or implant with a battery, silicone, pins, radiation pressurization, pacemakers, and large hip, knee, and shoulder replacements along with any external jewelry.
Only one body is cremated at a time since there is only enough space for one casket in a chamber. After each cremation, the chamber is cleared before the next incineration.
