There is often a degree of mystery surrounding the cremation process. That’s because most people never see what’s behind the scenes. But, understanding the process can help ease the anxiety that many people feel about the cremation process.
Today’s modern crematories use industrial furnaces designed just for cremation. The process takes about 2-3 hours to complete. Along the way, the crematory will take care to make sure that:
- The deceased is properly identified.
- The operator is safe.
- Care and respect are used.
Many facilities allow the family of the deceased to witness the cremation. Space is often limited so it is best to check with the cremation facility to find out how many people can attend.
The graphic below illustrates the key steps in the cremation process.
How the Cremation Process Works
Authorization and Identification
To make sure your loved one’s remains are properly handled, reputable crematories have strict procedures. The first step is to make sure that they have permission to take care of the cremation. Identification regulations vary by state. In most cases, you complete paperwork that provides the crematory with your authorization. The form will also ask for information such as who will pick up the remains and what type of container to use.
The facility you use defines the specific identification procedures based on industry recommendations. A typical identification procedure will include having a family member confirm the identity. Next, some sort of metal ID tag is placed on the body. This will remain throughout the process. Following the cremation, the identification tag is put with the remains.
Preparing the Body
Normally the body is bathed, cleaned, and dressed before identification. Unless you have a public viewing or you request it, the body is not embalmed.
Next, jewelry or other items that you would like to keep are removed. Medical devices and prosthetics that are mechanical or contain batteries are also removed. This is to prevent reaction during the cremation process. Items such as pins, screws, and joints remain in place. Recycling policies for medical devices vary by facility but in no case are the devices reused as is. They are disassembled, melted down, or disposed of in some other responsible method.
The Cremation Container
There are special caskets made for cremation or you can use a simple cardboard box. The key rule is that the container must be sturdy enough to hold the body and it must be combustible.
The Cremation Chamber (Retort)
A cremation chamber, referred to as a retort, is an industrial furnace that is large enough to hold one body. Fire resistant bricks line the chamber and can withstand temperatures up to 2000 degrees. Modern cremation furnaces follow according to strict environmental and air quality standards. Natural gas, propane, or diesel fuel the furnaces. They are also automated and computerized.
Removing the Metal
After incineration, the remains are cooled. The operator inspects the remains for remnants of metal left behind and removes them by hand or with strong magnets. The metal is often sent to a recycler.
Grinding the Remains
We refer to cremated remains as ashes but what is left behind is actually bits of bone. A special processor grinds the fragments into what we call “cremains.” This is what we mean when we refer to ashes.
After grinding, the ashes are placed in a plastic bag. The bag is placed in the urn that the family provides or in a temporary container. The urn or container with the ashes is returned to the family.
Both cremation and in-ground burial involve processes that work on the body. In cremation, heat is the process. In burial, the process is decomposition. Deciding which is right for you or your loved one depends on many factors. Cost, your religious beliefs, and your family traditions should all be considered. In the end, only you can decide which is right for your circumstances. We hope that having a basic understanding of the process will help you decide.
