Have you ever considered cremation for yourself or a loved one but felt unsure about the process? You might be wondering, “How does cremation work?”

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:

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 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:

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:

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:

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.

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:

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.

Are organs removed before cremation?

No, organs are not removed before cremation. The cremation process effectively breaks down all bodily tissues.

How long does a body take to cremate?

The cremation process typically takes between 3 to 5 hours total, including the final processing time. The exact duration can vary depending on factors like body size and the equipment used.
