How does cremation work?

Cremation uses intense heat to gently reduce a body to bone fragments, which are then processed into the fine ashes a family receives. After the necessary paperwork and any viewing, the person is placed in a simple combustible container and into the cremation chamber, which reaches around 1,400 to 1,800 degrees Fahrenheit. The process itself takes roughly one to three hours. Afterwards the remaining bone fragments are cooled and processed into a uniform consistency, then placed in a temporary container or an urn you choose and returned to the family, usually within a few days to a couple of weeks.

Step by step

The cremation process, step by step

Explained plainly and respectfully, so there are no surprises.

1

Authorisation & paperwork

Cremation cannot begin until the death is certified and the family signs authorisation. There is a legally required waiting period in most places, which is why it is never rushed.

2

Preparation

Any viewing happens first if the family wishes. Medical devices such as pacemakers are removed for safety, and the person is placed in a simple combustible container.

3

Identification

Reputable crematoriums follow a strict chain of identification with a unique reference that stays with the person throughout, so the ashes you receive are unmistakably your loved one's.

4

The cremation

The container is placed in the chamber, which reaches about 1,400 to 1,800°F. Intense heat reduces the body to bone fragments over roughly one to three hours. Each person is cremated individually.

5

Cooling & processing

The fragments are cooled, any metal (such as surgical implants) is removed and recycled, and the remains are processed into the fine, uniform ashes families recognise.

6

Return to the family

The ashes are placed in a temporary container or an urn or keepsake you choose and returned, usually within days to a couple of weeks.

How long it takes, and what you receive

The cremation itself takes about one to three hours, but the full process — paperwork, the legal waiting period, scheduling, cooling and processing — usually means the ashes are returned within a few days to two weeks. What you receive is around four to six pounds of fine, pale ash for an adult, roughly the volume of a large bag of flour. A standard adult urn holds about 200 cubic inches to accommodate this. The ashes are sterile and safe to keep at home, divide among family, or scatter.

Gentle options for the ashes

There is no single right thing to do, and no deadline to decide. Some of the ways families choose to honour ashes:

  • Keep them at home in an urn that suits the person.
  • Scatter them somewhere meaningful — with permission where required.
  • Bury or inter them in a plot, a columbarium niche, or a memorial garden.
  • Divide them so several family members each keep a portion.
  • Wear them in cremation jewelry that keeps the person close.
  • Mark the place with a stone, bench or plaque wherever the ashes rest.

Our guide to what to do with cremation ashes explores each of these in more depth, and our comparison of cremation vs burial helps if you are still weighing the decision.

Wherever the ashes rest, their story can rest with them. A QR memorial plaque on the urn, the garden stone or a bench opens a free digital memorial page — their photos, voice and the memories everyone shares — with a single scan.

A note on cost

Cremation is generally less expensive than burial because it removes the casket, cemetery plot and grave-opening costs. A simple direct cremation can run roughly $1,000 to $3,000, while a cremation with a service typically costs $6,000 to $7,000. Our full funeral cost breakdown sets out the numbers, and our how to plan a funeral guide puts the decisions in order.

A free digital memorial page to hold their whole story

Ashes hold the physical remains; a digital memorial page holds everything else — photographs across the years, a video, the music they loved, and the memories family and friends add. A QR plaque can link the place where the ashes rest straight to that page, so a single scan brings their whole story to life.

It is free to create and takes about five minutes. A QR plaque is optional and comes later — the page is the heart of it.

A marker for wherever they rest

The digital memorial page is free to create — start free and gather everyone's photos and memories. The physical QR memorial plaque mounts on an urn, a garden stone, a bench or a niche and opens that same page with a scan — a one-time keepsake (you will see the current price on the product page). It works beautifully for cremation, where there may be no traditional headstone to visit.

Common questions

How cremation works — FAQ

After the death is certified and the family authorises it, any viewing takes place and medical devices are removed. The person is placed in a simple combustible container and into the cremation chamber, which reaches about 1,400 to 1,800°F, reducing the body to bone fragments over roughly one to three hours. The fragments are then cooled, processed into fine ashes, and returned to the family in a container or urn.

The cremation itself takes about one to three hours, depending on the chamber and the individual. The full process — including paperwork, the legally required waiting period, scheduling, cooling and processing — usually means the ashes are returned to the family within a few days to about two weeks.

An adult cremation typically leaves around four to six pounds of fine, pale ash — roughly the volume of a large bag of flour. This is why a standard adult urn holds about 200 cubic inches. The amount varies with the person's size and bone density. The ashes are sterile and safe to keep, divide or scatter.

Yes. Reputable crematoriums cremate each person individually and follow a strict chain of identification, with a unique reference that stays with the person throughout the process. This ensures that the ashes returned to the family are unmistakably those of their loved one. You can ask any crematorium to explain their identification procedures.

There is no deadline and no single right choice. Families keep ashes at home in an urn, scatter them somewhere meaningful, bury or inter them in a plot or columbarium, divide them among relatives, or wear a portion in cremation jewelry. Many also mark the resting place with a stone, bench or plaque so there is somewhere to return to.

Generally yes. Cremation removes the cost of a casket, a cemetery plot and grave opening, so it usually costs less than burial. A simple direct cremation runs about $1,000 to $3,000, while a cremation with a full service typically costs $6,000 to $7,000, compared with $8,000 to $9,500 for a traditional burial.
