Over 60% of Americans are now choosing cremation, according to the National Funeral Directors Association's 2023 Cremation and Burial Report. That's a significant number, and it reflects a growing trend towards cremation as a preferred end-of-life choice.

But with such a significant shift, it's natural to have questions. Perhaps you've heard some things about cremation but wonder what happens during the process. What should you expect?

It's perfectly normal to have questions, and cremation can feel like a complex topic. This guide is here to shed light on the cremation process, answer those common questions, and help you navigate this important decision with confidence and peace of mind.

‍

How Does Cremation Work?

When a loved one passes away, cremation offers a respectful way to care for their remains. In simple terms, cremation involves using intense heat to carefully reduce the body to bone fragments.

These fragments are then processed into a fine powder, often referred to as ashes. This process allows families to say goodbye in a meaningful way and offers a variety of options for final disposition.

‍

Preparing for Cremation

Taking care of the necessary arrangements after a loved one's passing can feel overwhelming. When considering cremation, there are a few steps involved to ensure a smooth and respectful process:

‍

1. Authorizations and paperwork

A cremation authorization form will need to be signed by a legal next-of-kin. This form grants permission for the cremation to proceed. The cremation service provider that you choose will typically guide you through this paperwork and ensure all legal requirements are met.

‍

2. Body preparation

The body is cared for with respect and dignity throughout the cremation process. The staff begin by washing and sanitizing the body. This is an act of respect, providing the deceased with a final cleansing, and it also ensures the body is hygienically prepared for the cremation process.

‍

3. Choosing the cremation container

Selecting a cremation container is an important part of the cremation process. These containers, sometimes referred to as cremation trays or caskets, are designed to respectfully hold the body during the cremation process.

They are typically made from combustible materials that burn completely along with the body, leaving only minimal ash behind.

Common cremation container materials include:

‍

Wood: A popular and eco-friendly option, wooden containers come in various types of wood, each offering a unique aesthetic.
Cardboard: Another eco-friendly choice, cardboard containers are a simple and dignified option.
Composite materials: These containers are often constructed from recycled materials or a combination of combustible elements.
‍

The specific materials used in cremation containers are chosen for their ability to burn efficiently at high temperatures. This ensures a complete and respectful cremation process. Additionally, many cremation service providers offer containers made from sustainable or recycled materials, keeping environmental considerations in mind.

Prior to cremation, any metallic items such as jewelry or pacemakers will be carefully removed from the body. These items are not combustible and can damage the cremation chamber.

‍

4. Placement in the cremation chamber

Once the cremation container is selected and the body is prepared, it’s carefully placed within the cremation chamber. These chambers are designed and engineered to ensure a respectful and efficient cremation process.

Here's what you can expect:

‍

The retort is a secure, high-temperature chamber. It is constructed of fireproof materials and designed to maintain a controlled environment during the cremation process.
The transfer is handled with care and respect. Funeral home staff will ensure the container is securely placed within the retort.
Modern retorts are environmentally controlled. They operate with advanced temperature controls and emissions systems to minimize environmental impact.

‍

The Cremation Process

The cremation process itself takes place within the cremation chamber and involves a gradual increase in temperature. This process takes place in these phases:

‍

The cremation chamber is steadily brought to a temperature range of 1,400 °F to 1,800 °F (760 °C to 982 °C). This high heat is necessary to break down the body material efficiently.
‍
As the temperature rises, soft tissue begins to vaporize. This includes muscle, organs, and other bodily fluids. These elements are essentially turned into gas and water vapor, which are safely vented through the cremation chamber's filtration system.
Over time, as the cremation progresses and the peak temperature is reached, the remaining bone material undergoes a transformation. These bones dry out, become brittle, and ultimately reduce to bone fragments.

‍

Duration of cremation

The cremation process typically takes between 1.5 to 4 hours. The exact duration can vary depending on several factors, such as the body size and the desired level of bone fragmentation. Once the cremation cycle is complete, the chamber temperature is allowed to safely decrease before the remains are processed further.

‍

Cooling and Processing

Following the cremation cycle, the chamber temperature needs to return to a safe level before the remains can be accessed. This cooling process can take several hours. Once the chamber has cooled sufficiently, funeral home staff will carefully remove the cremated material.

Here’s what happens through this process:

‍

The cremated remains are handled with care and respect throughout the process. Funeral home staff are trained professionals who understand the emotional weight of this step.
Any remaining metallic items, such as screws from orthopedic implants, are meticulously separated from the cremated material using magnets or by hand.
These metallic elements are disposed of according to strict safety regulations and with environmental responsibility in mind. Many funeral homes have established recycling programs for these materials.

‍

Reduction to Ashes

The cremated material remaining after cooling and metallic object separation consists primarily of bone fragments. These fragments are then processed further to create what most people refer to as ashes.

Creating a fine powder:

‍

The bone fragments are carefully placed in a specialized processor. This processor uses grinding blades to gently pulverize the fragments into a fine, uniform powder.
The resulting powder, often referred to as cremated remains or ashes, is a respectful and tangible reminder of your loved one. The ashes typically have a light gray or off-white color and a slightly coarse texture.

‍

Handling the Ashes

Once the cremation process is complete and the cremated remains have been processed into ashes, families have the option to collect them and choose their final resting place.

Cremation providers give a temporary urn to hold the ashes until a permanent urn is chosen. Families can arrange a time to collect the ashes from the funeral home at their convenience. Some cremation providers deliver the ashes to your home or arrange for shipping across the U.S. via post.
For families, choosing an urn can be a way to personalize the final resting place for your loved one. Urns come in a wide variety of materials, styles, and sizes. Consider what would best reflect their loved one's preferences when making this selection. Funeral homes typically have a selection of urns available or can help find the right one from an outside vendor.
Cremation providers are meticulous about ensuring proper identification throughout the cremation process so that the ashes sent to the family are the correct ones.

‍

Choosing the Final Resting Place for the Ashes

There are many options available for families to consider when choosing a final resting place for their loved one's ashes. The most suitable choice will depend on individual preferences, religious beliefs, and cultural traditions.

Here are some common options for placing cremated remains:

‍

Columbarium: A columbarium is a structure designed specifically for the respectful placement of cremation urns. These structures are often located within cemeteries and offer niches or compartments for urn placement. Some columbariums offer beautiful and serene settings for families to visit and remember their loved ones.
Scattering: Scattering ashes in a meaningful location can be a beautiful and symbolic way to lay a loved one to rest. This could be a favorite hiking trail, a cherished beach, or any place that held special significance for the deceased.

It's important to check local regulations and obtain any necessary permits before scattering ashes on public or private property.
Keeping at home: Some families choose to keep their loved one's ashes at home in a designated urn or memorial space. This can offer a sense of comfort and closeness for those who wish to have their loved one nearby.
Burial: Cremated remains can also be buried in a cemetery plot, family plot, or memorial garden. This option allows families to have a designated place to visit and remember their loved one.

‍

Additional considerations:

Some families choose to divide the ashes among several locations, keeping some at home and scattering some in a meaningful place.
There are also emerging options for cremated remains, such as memorial reefs placed on the ocean floor or tree urns, which can be explored based on the family's wishes.

Ultimately, the most important factor is choosing a final resting place that feels respectful and brings comfort to the family during this difficult time.

Frequently Asked Questions

What exactly happens during the cremation process?

During cremation, the body is carefully placed in a special chamber and gradually heated to a high temperature to break down the body materials. Soft tissues like muscle, organs, and fluids are vaporized and safely vented through the chamber's filtration system. Bone material dries out, becomes brittle, and breaks down into bone fragments.

Finally, after the chamber cools, the remaining cremated material is processed into a fine powder, often referred to as ashes.

‍

What is removed from a body before cremation?

Any medical devices or prosthetics that could be hazardous during the cremation process, such as pacemakers, are carefully removed beforehand. Jewelry and other personal belongings are also typically removed and returned to the family.

‍

Do they drain the blood before cremation?

No, there is no need to drain blood before cremation. The high temperatures during cremation vaporize bodily fluids along with soft tissues.

‍
