How Cremation Works: A Step-by-Step Guide to the Cremation Process

Cremation has become an increasingly popular choice for end-of-life arrangements. In fact, according to the Cremation Association of North America, over 57% of Americans choose cremation over traditional burial. But how does cremation work? What happens during the cremation process? This article walks you through everything you need to know—from the technical steps to the final outcome—so you can make informed decisions with confidence.

What Is Cremation?

Cremation is a method of final disposition that uses intense heat to reduce a body to bone fragments, which are then processed into fine ashes. These ashes—also known as cremated remains or cremains—are typically placed in an urn and returned to the family.

How Cremation Works: Step-by-Step

1. Authorization and Preparation

Before cremation can begin, several legal and procedural steps must occur:

• The family or legal representative signs a cremation authorization form.

• The funeral home collects the death certificate and complies with state regulations.

• Any medical implants (like pacemakers) are removed, as they can be hazardous during cremation.

2. Identification and Tagging

To ensure proper handling:

• The body is tagged with a unique ID number.

• This ID follows the remains through every step of the cremation process.

3. Placement in Cremation Container

The body is placed in a combustible, rigid container, usually made of cardboard or wood. This container helps facilitate safe and respectful handling.

4. Cremation in the Chamber

• The container is placed in a cremation chamber (also called a retort).

• The chamber is heated to temperatures between 1,400°F and 1,800°F.

• After 2 to 3 hours, the body is reduced to bone fragments and gases.

5. Cooling and Processing

• After the cremation, the chamber is cooled.

• Bone fragments are collected and placed in a cremulator, which grinds them into a fine, sand-like texture.

6. Return of Ashes

• The processed ashes are placed in a temporary container or an urn selected by the family.

• A certificate of cremation may be included.

• The ashes can be kept, scattered, buried, or can be preserved forever in a piece of memorial art.
