The Process And Science Of Cremation


For centuries, cremation has been the most popular way to deal with a deceased loved one. Cremation is the process of burning the body at high temperatures until nothing but ashes remain. It takes about an hour and a half for a body to be fully cremated.

However, it’s not as easy as just setting fire to something to get rid of it in that amount of time. The heat used will need to be intense enough so that all organic material can combust, and there needs to be enough oxygen present for this process to take place on its own because if you leave out either factor, then what remains will still be recognizable human remains rather than ash.

This breaks down into a couple of steps:

The first involves cutting off any remaining limbs or damaged pieces of the body to reduce its size and fit it into a cremation chamber. There are three methods used for this, depending on the circumstances. The first is known as “cremation by sawing,” which breaks up the body into pieces small enough to fit into a cremation chamber using an industrial saw heated to around 1000 degrees Celsius.

An alternate way is known as “cremation by grinding,” which uses an industrial grinder that quickly breaks down any bone or other hard piece left after the body has been burned. Crematories tend to prefer this method since it doesn’t take very long and because the grinding process creates more refined pieces of bone, taking up less space in the heating chamber. This method is also preferred by hospitals since it can be done quickly by a machine with no need for an operator according to Eternal Cremations.

This all remains true as long as the bones aren’t too brittle or damaged beforehand. The last way to break down the body is by cremation using manual labor (manual cremation), where they are manually broken apart using sledgehammers and other tools until they fit into the chamber. This is still used today but only in rare cases and usually if there were some reason that prevented them from being taken somewhere else to have it done.

The third step has to do with preparing any remaining organs left in the body so that they can be disposed of properly. This is done by first draining out any blood and other fluids inside it. The organs are then removed from the body and placed in a container known as an “organs-bag,” or sometimes just called a “cerebral-bag’, which contains formalin (a mix of formaldehyde, water, and methanol) to help them harden for easier disposal.

In addition to this step, the body may also go through some sort of embalming process before being cremated if it’s not already has been done beforehand. Embalming involves injecting preservatives into the deceased’s arteries in order to prevent rapid decomposition while preserving its appearance at least somewhat.
The next step takes place when the corpse is placed inside a special oven which has holes on top of it so that fire can enter the chamber from all angles, as well as holes on its floor for air circulation. The heating element in this chamber runs at roughly 3,600 degrees Fahrenheit and will heat up whatever’s inside until everything combusts or burns off completely.

In the oven, the temperature will be much hotter than that since most of it will have to go through special insulation designed to keep it from heating up too much and destroying that part of the crematorium. This process takes anywhere from a few hours to well over twenty-four hours, but as long as all organic material is burned off and there’s enough oxygen present for it to happen, then it will be considered cremation once completed.

If any part of the body or its casket were left out after this time, then they would still probably technically count as human remains rather than ashes – though depending on how much was left behind, you might have trouble differing between the two. In order to make sure that everything inside has been properly turned into ash, some facilities run what they call an “ash test.” This involves pulling out a small sample from one of the ovens that’s going through cremation at the time and placing it in a special machine that can tell how much of its carbon (organic) content has been turned into ash. If there’s too much leftover, then they’ll keep on cremating up until it passes, however, if all of the body was already gone, then you wouldn’t be able to perform this test because there wouldn’t be any remains present for them to extract from.

The last step consists of disposing of everything that was left over after successful cremation has occurred. The ashes are placed in an urn or other container, and many families will take these with them to memorial services, where they’ll often get spread out somewhere else, such as a cemetery or forest.

Crematories often pump in a considerable amount of dry air into their chambers in order to cool down everything else inside so they can quickly dispose of it without having to wait for everything to reach room temperature. This air then slowly mixes with what’s inside, which eventually creates bio-ash (ashes mixed with biological matter) as well as gypsum crystals from any bone fragments or other pieces that remained behind during the initial stages of this process.

Cremation has been utilized for thousands of years, but the process of it has changed over time as technology and findings have improved. The whole process starts with an industrial crematorium where there are special ovens that will have a fire running inside. It’s important for many people who have lost a loved one to know as much as possible about the options they have. We hope that this blog post has been helpful in understanding the various steps involved in both cremation and burial.
