Understanding the Cremation Process: Step-by-Step Overview

What are the identification and authorization procedures?

The cremation process begins with careful identification and authorization procedures to ensure the correct handling of the deceased. When a body arrives at the crematorium, it is first thoroughly checked against accompanying documentation. This includes verifying the name, date of birth, and other identifying details.

Next, the necessary legal paperwork must be completed. This typically involves obtaining authorization from the next of kin or the person with the legal right to make decisions about the deceased’s remains. In the UK, a cremation application form (Cremation 1) must be completed, along with a medical certificate (Cremation 4) signed by two doctors, unless a coroner has been involved.

Once all documentation is in order and verified, a unique identification tag is assigned to the body. This tag remains with the deceased throughout the entire cremation process, ensuring traceability and preventing any mix-ups.

How do simple cremation services work step by step?

Simple cremation, also known as direct cremation, is a no-frills option that has gained popularity in recent years. Here’s a step-by-step breakdown of what typically occurs:

  1. Collection: The deceased is collected from the place of death and transported to the crematorium or funeral home.

  2. Preparation: The body is prepared for cremation. This usually involves removing any medical devices or implants that could be hazardous during the process.

  3. Cooling: The body is kept in a refrigerated facility until the cremation can take place.

  4. Final check: A final identification check is performed before the cremation begins.

  5. Cremation: The body is placed in a cremation chamber and the process is carried out.

  6. Processing: After cooling, the cremated remains are processed into a fine ash.

  7. Return: The ashes are placed in a simple container and returned to the family or their designated representative.

This streamlined process eliminates the need for embalming, viewing, or a funeral service before cremation, making it a cost-effective choice for many families.

What happens during the cremation itself? A detailed explanation

The actual cremation process takes place in a specially designed cremation chamber, often called a retort. Here’s what occurs:

  1. The body, in a combustible container or casket, is placed in the cremation chamber.

  2. The chamber is sealed, and the temperature is raised to between 760 to 1150 degrees Celsius (1400 to 2100 degrees Fahrenheit).

  3. The intense heat reduces the body and container to bone fragments and ash. This process typically takes 1 to 3 hours, depending on factors such as body size and the type of cremation chamber used.

  4. Once the cremation is complete and the chamber has cooled, the remains are carefully swept out.

  5. Any metal objects, such as surgical pins or fillings, are removed using a magnet or by hand.

  6. The bone fragments are then processed in a machine called a cremulator, which grinds them into a fine, sand-like consistency. This is what we commonly refer to as “ashes.”

It’s important to note that throughout this process, only one body is cremated at a time, and modern cremation chambers are designed to ensure that the ashes are kept separate and intact.

How are the ashes collected and returned to the family?

After the cremation and processing are complete, the ashes are carefully collected and placed in a temporary container or an urn if the family has provided one. The amount of ashes typically weighs between 1 to 3 kilograms (2 to 6 pounds), depending on the size of the deceased.

The crematorium will then contact the family or their representative to arrange for the collection of the ashes. In the UK, crematoria are required to retain ashes for a minimum of 14 days to allow families time to decide on their preferred method of collection or scattering.

When collecting the ashes, the family will usually need to sign a release form. They may choose to keep the ashes at home, scatter them in a meaningful location, or inter them in a columbarium or cemetery plot. Some families opt for more creative memorialization options, such as incorporating ashes into jewelry or artwork.

What cremation options are available in the United Kingdom?

In the United Kingdom, several cremation options are available to suit different preferences and budgets:

  1. Direct Cremation: This is the simplest and most affordable option, with no viewing or ceremony before cremation.

  2. Traditional Cremation: This includes a funeral service before the cremation, often with the body present in a casket.

  3. Witnessed Cremation: Family members can be present to witness the beginning of the cremation process.

  4. Green Cremation: Some facilities offer more environmentally friendly options, such as water cremation (alkaline hydrolysis), though this is not yet widely available in the UK.

  5. Private Cremation: This option allows for a more personalised service, often at a time that suits the family best.

When considering cremation services, it’s advisable to research local providers and compare their offerings. Many crematoria and funeral homes in the UK now provide detailed information about their services online, making it easier for families to make informed decisions during a difficult time.
