The cremation process isn’t a subject most people know too much about- until they need to. So you’re probably planning at the moment or need to make some last-minute decisions.

What is Cremation?

The cremation process is fairly straightforward. When a person dies, their body is taken to a funeral home or crematorium. The required paperwork is completed and shortly after, the cremation will begin.

The body is then placed into a cremation chamber and subjected to extreme heat.

The temperature is so intense it vaporizes most of the organic matter and incinerates the bones, which are reduced down to fragments.

After a cooling period, they are ground to a finer consistency using a cremulator. The remains are then collected and presented to the family.

Below we’ll go into more detail about this cremation process.

Cremation Chamber
Cremation Chamber

A crematorium is a facility where cremations are performed. Occasionally, funeral homes will have their own crematorium. In most cases, it is a separate facility. Within the facility is one or more cremation chambers, also known as retorts.

The chamber is normally fueled by propane or gas. It reaches a temperature of about 2,000 degrees Fahrenheit. Most crematoriums are modernized and have equipment that is controlled electronically.

How does a Crematorium work?

Family Viewing Cremation
Family Viewing Cremation

Within the crematorium, there is typically a room with seating and a window, which has a view of the chamber. If desired, the family is able to watch the cremation process as it is taking place.

In addition, you might see a retail area. This area normally contains different types of containers, such as urns and keepsakes, which you can purchase for the ashes.

The Cremation Process

After the documentation is completed and signed, the cremation process can then proceed. Below are some details of the cremation process.

The Funeral service

A funeral or memorial service does not always take place, such as with a direct cremation.

However, if there is to be a funeral ceremony, it can take place either before the cremation process with the whole body present, or after the cremation process with the ashes present.

Identification of the deceased

When choosing a crematory, ensure that you check on their procedures and how they operate. Every funeral home has slightly variations to their cremation process.

One very important aspect is how they identify the body prior to the cremation process to ensure that you receive the correct cremains.

This is done with a document or tag. It should accompany the body from the time they pick it up until the ashes are given to the family.

Preparing the body

Numerous steps are taken in order to prepare the body for the cremation process. Initially, they remove anything from the exterior of the body that cannot be cremated, such as jewelry.

Pacemakers can be explosive when subjected to high heat. Therefore, it must be removed from the body prior to the cremation process.

Radioactive therapeutic implants contain mercury, which is detrimental to the environment and should be removed prior to the cremation process.

Take a look at our guide on how a body is prepared for cremation.

Direct Cremation
Simple Cremation Casket

The deceased is typically placed into some type of container. It may be specifically for the cremation process, also referred to as an alternative casket. This casket is usually constructed of wood or sturdy cardboard.

Since a casket is not required, the body is occasionally wrapped in a lovely shroud instead.

The Cremation

The cremation chamber or retort is preheated to around 2,000 degrees Fahrenheit for the cremation process.

When that temperature is attained, the casket or body typically moves into the chamber automatically. In less modern facilities, this is done manually.

How long does it take to cremate a body?

It takes an average of two hours for the cremation process to complete or until the body is reduced to bones and fragments.

After the cremation process, the cooling process takes place, which normally takes about thirty minutes to an hour.

Collecting the ashes

The ashes are examined and any type of metal is removed, such as pins or screws from surgical procedures. This is done manually or with a magnet.

Afterward, the bone fragments are placed into a type of grinder called a cremulator. This piece of equipment pulverizes the cremated remains into a gritty sand-like consistency.

Subsequently, the ashes are usually placed into a temporary container, which is then given to the family.

Transporting ashes

When the ashes are going to different families, you may need to send the ashes or travel with them. It’s good advice to always travel with a simple container like the one above.

Common questions about the Cremation Process

Do funeral homes have a crematorium?

Some funeral homes have their own crematorium however most contracts with a third-party facility. There may be an extra charge for transporting the body to the crematorium.

Additionally, the charge for the cremation may not be included in the funeral home’s bill. Be sure to ask the funeral director if it will be separate as well.

What are human ashes made of?

Bone Matter After Processing

The word ashes is actually not an accurate description. The course, sand-like matter that you receive after the cremation is human skeleton remains.

Bone is comprised of calcium phosphates and carbonates, which is what makes the bones strong and not easily broken down by the intense heat of the chamber.

Although all the organic body tissue is eradicated by the heat and the fluids evaporate, some of the bone and bone fragments endure. The ashes you receive are actually bone matter that has been ground by a cremulator.

How much ash REMAINS after cremation?

Many people are surprised at the number of ashes they receive. The remains of an average adult person weigh approximately five pounds.

Our bones naturally become less dense as we age. The age of the person, their size, and their bone density can also determine the number of ashes.

Can you rent a casket?

Rental Casket With Removable Insert

Yes, caskets are often rented. This most often occurs when a funeral or memorial service will be held before the cremation.

It makes more economic sense than purchasing an extremely costly casket, which would be destroyed during the cremation process.

rental casket looks the same as a typical one, except it has an inexpensive removable insert, otherwise known as an alternative casket.

The insert, which actually contains the body, is usually constructed of wood or sturdy cardboard.

After the service, the alternative casket with the body is removed and the deceased is cremated in that container.

Since the body never touches the outer casket, the crematorium can rent it out again. For that reason, renting is considerably less than purchasing a casket.

What is direct cremation?

For someone desiring simplicity and low cost, direct cremation is the most straightforward and economical option. Even though a funeral home sometimes makes the arrangements, there is no memorial service, wake, or viewing before the cremation.

In most cases, a funeral home’s sole responsibility other than the necessary paperwork is transporting the body to the crematorium.

After the cremation process, the ashes are given to the family.

Is a burial more expensive than cremation?

Other extras not needed with cremation

In addition, the funeral home and staff are not required, which is commonly another one of the largest expenses.

Unless you intend to bury the cremains, there is no need to buy a plot and purchase a grave marker.

The cost of burial

With a burial, the cost of a casket alone is between $2,500 to $10,000 and more. The total cost for burial is usually a minimum of $10,000.

Do human ashes pose any health hazards?

They pose no health hazards and have a lower carbon footprint, however there are a few stipulations that should be considered regarding the scattering of ashes.

As with fertilizer, ashes that are scattered on the ground in a condensed area can possibly burn the grass and plants. To ensure this doesn’t happen, they should be spread out over a larger area.

In some areas, it is also recommended that cremated remains not to be scattered in an area with a delicate ecosystem, such as mountain peaks. Check with the rules in your specific area.

Many people may choose to store cremation remains. Take a look at our guide on how to store cremated remains properly.

What does the bible say about cremation?

Additionally, God does not denounce cremation as he does some other religious practices.

Our article about cremation and the bible goes into more depth with verses, references, and whether God is against it.
