Does a corpse still decay 100% in a sealed air-tight coffin?

the flesh will be decayed \ninitially with aerobic bacteria\nafter oxygen become depleted\nanaerobic bacteria take over\ndegradation is less efficient in lacking of oxygen\nand I think the number of surviving bacteria will also be less than that in sufficient of air\nthe bones should be hard to be degraded in this situation

Is it within a vacuum?\n\nIf not, and if through your above given conditions resulted in air being compressed or what have you then I guess it would.

In the days before refrigerated mortuaries, to hide the smell of the body decomposing. Sorry, that's gross, but it's also true.

Wow. I guess it depends on your religion.\nIn Judaism, the dentures are removed, along with all other items that are not part of the body.\n\nI think that in religions/cultures where the body is embalmed and put on display in an open coffin, with makeup and clothes and everything, the dentures would be left in.

you should watch a cemetery for a few days, When someone dies the ground workers dig the hole the night before the person who hole it is gets buried. Wait until night time, bring body and shovel. Dig the hole deeper, put your dead body in, cover up. The next day they will put the other dead person's casket over it. NO WORRIES!:)

when scuba diving the object is to put enough air into your bouancy compensator(bc) to remain neutrally bouant at a point. so you wont sink or float anymore. its basically balancing out the pressure above you with the pressure below you by surrounding yourself with air. so if taken to a certain depth maybe a decomposing body would release enuff air to remain neutrally bouant at a certain depth.

I can answer this question, I used to work in a memorial park.  In most states here in the US, you by law have to be buried in a cement vault in the ground.  The reason for this is not to contaminate any sources of ground water.  For in ground burial, a standard 6ft deep hole is dug, the hole is usually 6 1/2ft. in length, and 3 1/2, to 4ft. in width.  The cement vault is placed in the hole first, then the coffin containing the deceased is lowered into the vault, and sealed with a cement lid using a sealant to prevent leakage.  \n\nI'm sorry I really don't know the methods of Jewish burial.  The cemetery I worked for was used for people of the christian faith.  We do have a Jewish cemetery in our area, Driving past it, I have seen raised tombstones.  It appears that they use both raised, and flat tombstones

As meatwad said, it depends a lot on where the bones are, and what they are exposed to after death.\n\nBuried underground and locked in a casket, bones could last for centuries or more.\n\nIn a shallow, acidic soil in a tropical climate, exposed to insects, constant rainfall, rodents, and fungi, the same skeleton could easily disintegrate to almost nothing in less than a year.\n\nLocked in frozen ground in the Arctic, or in a desert, or underneath layers of silt at the bottom a river, the bones could last for thousands of years.  In some cases, even long enough for the minerals in the bones to interact with percolating ground water and fossilize.  Fossilized bones, if they remain protected from erosion or mechanical damage can last millions or even hundreds of millions of years.

Premature Burial.\nIn other words (for those ignorant twats among you)...being buried alive.\n\nThink about it.  You fall into an unusually deep sleep or perhaps a coma and people mistake it for death.  Perhaps you fell victim to some voodoo curse that removes your vital signs temporarily.  They have the funeral and then bury your ass in your fancy coffin in 6 feet of dirt.\nYou wake up the first night after you are buried.  It is dark and confined.  What happened to you?  Last thing you remember was going to sleep normally.  Imagine the terror.  And imagine it escalate when you feel the silky linings of your casket and realize what has happened to you.  You pound feverishly at the coffin lid but no one will be hearing you.  You will just fade away when the oxygen does.\nIt is cruel because it allowed you enough time to become aware and then to realize your fate and then understand that Jesus isn't there to help prevent your untimely demise.  \n\nOf course being buried alive in other, less traditional ways is just as bad.  \nLike if you were buried alive in a molasses flood.  Trapped as if you were a prehistoric mosquito in amber.\nYour scientific importance in 1000 years matters little to you as you understand you are being buried in Aunt Jemima.\nMaybe millions of dog volunteer workers from around the world will come and lick you out out of your hardened, sweet and sticky tomb but I doubt it.  \n\nThere are some other bad ways to die my goodbitches, but I am off to get some lunch.\n\n\n.

******************\nDONT TRY THIS AT HOME :D\n******************\nAn important man has died and his body needs to be prepared for burial. The process of mummification has two stages. First, the embalming of the body. Then, the wrapping and burial of the body. \n\nFirst, his body is taken to the tent known as 'ibu' or the 'place of purification'. There the embalmers wash his body with good-smelling palm wine and rinse it with water from the Nile.\n\nOne of the embalmer's men makes a cut in the left side of the body and removes many of the internal organs. It is important to remove these because they are the first part of the body to decompose.\n\nThe liver, lungs, stomach and intestines are washed and packed in natron which will dry them out. The heart is not taken out of the body because it is the centre of intelligence and feeling and the man will need it in the afterlife.\n\nA long hook is used to smash the brain and pull it out through the nose.\n\nThe body is now covered and stuffed with natron which will dry it out. All of the fluids, and rags from the embalming process will be saved and buried along with the body.\n\nAfter forty days the body is washed again with water from the Nile. Then it is covered with oils to help the skin stay elastic.\n\nThe dehydrated internal organs are wrapped in linen and returned to the body. The body is stuffed with dry materials such as sawdust, leaves and linen so that it looks lifelike. \n\nFinally the body is covered again with good-smelling oils. It is now ready to be wrapped in linen.\n\nn the past, when the internal organs were removed from a body they were placed in hollow canopic jars.\n\nOver many years the embalming practices changed and embalmers began returning internal organs to bodies after the organs had been dried in natron. However, solid wood or stone canopic jars were still buried with the mummy to symbolically protect the internal organs. \n\nImsety the human-headed god looks after the liver. Hapy the baboon-headed god looks after the lungs. Duamutef the jackal-headed god looks after the stomach. Qebehsenuef the falcon-headed god looks after the intestines.\n\nThe body has been cleaned, dried and rubbed with good-smelling oils. Now it is ready to be wrapped in linen.\n\n***************\nWrapping the mummy\n***************\n\nFirst the head and neck are wrapped with strips of fine linen. Then the fingers and the toes are individually wrapped. \n\nThe arms and legs are wrapped separately. Between the layers of wrapping, the embalmers place amulets to protect the body in its journey through the underworld.\n\nA priest reads spells out loud while the mummy is being wrapped. These spells will help ward off evil spirits and help the deceased make the journey to the afterlife. \n\nThe arms and legs are tied together. A papyrus scroll with spells from the Book of the Dead is placed between the wrapped hands.\n\nMore linen strips are wrapped around the body. At every layer, the bandages are painted with liquid resin that helps to glue the bandages together. \n\nA cloth is wrapped around the body and a picture of the god Osiris is painted on its surface. \n\nFinally, a large cloth is wrapped around the entire mummy. It is attached with strips of linen that run from the top to the bottom of the mummy, and around its middle.\n\nA board of painted wood is placed on top of the mummy before the mummy is lowered into its coffin. The first coffin is then put inside a second coffin. \n\nThe funeral is held for the deceased and his family mourns his death. \n\nA ritual called the 'Opening of the Mouth' is performed, allowing the deceased to eat and drink again.\n\nFinally, the body and its coffins are placed inside a large stone sarcophagus in the tomb. Furniture, clothing, valuable objects, food and drink are arranged in the tomb for the deceased.\n\nNow his body is ready for its journey through the underworld. There his heart will be judged by his good deeds

No, there is no reason for underwear on the deceased.\nAll that is supplied is their outer garments.\nIf the body is too big for the casket, there will also be an absence of shoes.\nYet, again it also can depend upon the requests of the next of kin to the deceased or who is paying for the services as well.

Because, if you are buried 7 feet under, its too much to dig out from if you were buried alive... and 5 feet under, the smell would get out if you were actually dead when buried... \n\n6 feet was the perfect compromise between the danger of being buried alive and smell...

The dead may return as vampires after they are buried to ward off them rice and other substances are thrown in the coffin. .\n\nTo make sure that the dead will not return as vampires, the burial has to take place in such a manner that it ensures a successful transition of the soul to the place where it is meant to go. Which means that the proper procedures have to be observed before, during and after the funeral. Especially if, according to the local belief, there is a risk that the deceased might become a vampire. Objects or substances such as rice,  are used to ward off vampires may be put into the coffin. Supposing that the vampire has managed to leave its grave, there is still no reason to panic. For there is a large variety of objects and substances (rice etc.)that are thought to ward off vampires-.

Embalming as practiced in the funeral homes of the Western World uses several steps. Modern embalming techniques are not the result of a single practitioner, but rather the accumulation of many decades, even centuries, of research, trial and error and invention. A standardized version follows below but variation on techniques is very common.\n\nThe first thing an embalmer should do is verify the identity of the deceased (normally via wrist or leg tags) and perform basic tests for signs of death, such as clouded-over corneas, lividity, and rigor mortis. While people awakening on the mortuary table is largely the province of horror fiction and urban myth, testing for death is still a final additional precaution. Any clothing on the corpse is removed and set aside; jewelry, also, is inventoried. A modesty cloth is then placed over the deceased's genitalia for dignity. Following this the corpse is washed in disinfecting and germicidal solutions, shaved, and groomed. The embalmer bends, flexes and massages the arms and legs to relieve rigor mortis. The eyes are closed and kept closed with an eyecap that keeps them shut and in the proper expression. The mouth may be closed via suturing with a needle and ligature, using an adhesive, wire or a needle injector, a specialised device most commonly utilised in North America and unique to mortuary practise. Care is taken to make the expression look as relaxed and natural as possible and ideally a recent photograph of the deceased while still living is used as a template. The process of closing the mouth, eyes, shaving etc is collectively known as setting the features.\n\nThe actual embalming process usually involves four parts:\n\nArterial embalming, which involves the injection of embalming chemicals into the blood vessels, usually via the right common carotid artery. Blood is displaced from the right jugular vein. The embalming solution is injected through a mechanical pump and the embalmer massages the corpse to ensure a proper distribution of the embalming fluid. In case of poor circulation, other injection points are used. \nCavity embalming, the suction of the internal fluids of the corpse and the injection of embalming chemicals into body cavities, using an aspirator and trocar. The embalmer makes a small incision just above the navel and pushes the trocar in the chest and stomach cavities to puncture the hollow organs and aspirate their contents. He then fills the cavities with concentrated chemicals that contain formaldehyde. The incision is either sutured closed or a "trocar button" is screwed into place. \nHypodermic embalming, the injection of embalming chemicals under the skin as needed. \nSurface embalming, which supplements the other methods, especially for visible, injured body parts. \nMost good embalmings are completed in two or three hours, although an easy case may take less and complicated cases can take days.
