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.
If the ground is light, dry soil, decomposition is quicker. Generally speaking, a body takes 10 or 15 years to decompose to a skeleton. Some of the old Victorian graves hold families of up to eight people. As those coffins decompose, the remains will gradually sink to the bottom of the grave and merge.
However, on average, a body buried within a typical coffin usually starts to break down within a year, but takes up to a decade to fully decompose, leaving only the skeleton, Daniel Wescott (opens in new tab), director of the Forensic Anthropology Center at Texas State University, told Live Science.
But by 50 years, the tissues will have liquefied and disappeared, leaving behind mummified skin and tendons. Eventually these too will disintegrate, and after 80 years in that coffin, your bones will crack as the soft collagen inside them deteriorates, leaving nothing but the brittle mineral frame behind.
Almost all caskets decompose eventually. Wicker and Plywood caskets will decompose within 5 years, while wooden caskets will decompose within several decades. Metal and fiberglass caskets can take hundreds or even thousands of years to fully decompose.
The rate at which this occurs varies depending on the type of casket, the elements in the soil, and its condition. Typically, wooden coffins may take a few years to collapse after being buried, while metal ones are more resistant and can last longer.
To Protect the Corpse from Being Stolen. Snatching dead bodies was common in many parts of England and Scotland in the early 1800s. Therefore, graves were always dug six feet deep to prevent body snatchers from gaining access to the buried remains.
It is a common practice to cover the legs as there is swelling in the feet and shoes don't fit. As part of funeral care, the body is dressed and preserved, with the prime focus on the face. Post embalming, bodies are often placed without shoes; hence covering the legs is the way to offer a dignified funeral.
As you can see most funeral homes can hold a body indefinitely – but there will likely be holding fees. So, if you can you should speed the process up by finding a reliable funeral home that can deal with the paperwork.
If a body is buried in a coffin very deep the ground it could take 50 years for all the tissue to de-compose, and hundreds of years for the bones to fully decay.
Putrefaction (4-10 days after death) – Autolysis occurs and gases (odor) and discoloration starts.
A hospital is allowed to keep the body of a deceased person in a hospital mortuary for up to 21 days after the date of death (section 80 of the Regulation). Hospital mortuaries are designed for the short-term storage of a limited number of bodies of persons that pass away in hospitals.
After two weeks, the body starts to bloat and change its color to red after the blood present in the body starts to decompose. Once the corpse surpasses the fourth week, you can witness liquefaction in the rest of the remains. The teeth and nails also begin to fall during this time frame.
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.
During cremation, the body parts that do burn consist of organs, soft tissue, hair, and skin, while the water in our bodies evaporates. The body parts that do not burn are bone fragments.
OPEN-CASKET FUNERAL ETIQUETTE
If they have an open casket viewing, make sure you follow proper funeral etiquette: DON'T touch the body under any circumstances. Sometimes the casket has a glass to prevent this from happening.
We don't remove them. You can use what is called an eye cap to put over the flattened eyeball to recreate the natural curvature of the eye. You can also inject tissue builder directly into the eyeball and fill it up. And sometimes, the embalming fluid will fill the eye to normal size.
A rather large overstuffed pillow is included in the interior package of a finished casket. This pillow helps to hold the decedent in an inclined position. This position helps present a naturally comforting presentation to the survivors.
For example, human burial legislation in NSW requires the top of the coffin to be buried no less than 900 millimetres below the natural surface level of the soil. This works out to around three feet. When you take the cask dimensions into account, you're looking at an overall single-coffin depth of four to five feet.
“In particular, the prone burial was linked to the belief that the soul left the body through the mouth. Burying the dead face-down was a way to prevent the impure soul threatening the living,” anthropologist Elena Dellù from Italy's Institute of Archeology told Lorenzi.
A grave will normally hold up to three standard size coffins however no guarantee of this can be given.
We think this is an urban legend. 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.
So, do open caskets smell? Bodies at formal open casket funerals will not smell bad due to having been embalmed shortly after death. However, smells such as perfumes or flowers may be common at an open casket funeral. Bodies with unavoidable smells will typically not be offered an open casket funeral.
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.
