When a loved one is cremated, the coffin they are placed in is cremated along with them. The entire coffin is placed inside the cremation chamber, where it is exposed to extremely high temperatures reaching up to 1,800 degrees Fahrenheit. The cremation process typically takes about 90 minutes, during which both the body and the coffin are reduced to ash.

Because of this, many people choose a coffin specifically designed for cremation. These coffins are made to burn cleanly and efficiently, ensuring the process goes smoothly without leaving behind any problematic materials.

Once cremation is complete, the ashes including fragments of bone and coffin material are extremely hot. They are allowed to cool before being carefully processed. A machine then grinds any remaining fragments into a fine, uniform ash, which is transferred into an urn or container selected by the family.

Can Every Coffin Be Used for Cremation?

Not all coffins are suitable for cremation. Only coffins made from combustible materials are permitted inside the cremation chamber. Caskets made from non-combustible materials like stainless steel, bronze, copper, or other metals cannot be used.

Before cremation begins, the crematorium staff carefully inspect the coffin and the body to remove any items that could cause issues. This includes pacemakers, which can explode under high heat, and glass objects. They also remove non-combustible components from the coffin itself, such as metal sidebars or handles.

Types of Coffins That Can Be Cremated

There are several types of coffins that are compatible with cremation. Here’s a breakdown of the most common options:

Wooden Coffins

Traditional wooden coffins made from materials such as birch, mahogany, oak, and pine are fully compatible with cremation. However, any metal handles or decorations are typically removed beforehand.

There are also wooden coffins specifically designed for cremation. These are made from untreated woods like pine or poplar and contain no metal or non-combustible parts, ensuring a complete and clean burn.

Wool or Fleece Coffins

Wool or fleece coffins are made by draping natural wool over a fiberboard frame. They are entirely biodegradable and ideal for cremation, with eco-friendly handles made from materials like jute. These coffins are also popular for green burials.

Wicker Coffins

Wicker coffins are woven from fast-growing plant fibers such as willow, bamboo, rattan, or seagrass. These materials are sustainably farmed to protect natural resources. Despite their lightweight construction, wicker coffins are strong enough to support up to 350 pounds, making them a practical and eco-friendly choice for cremation.

Cloth Coffins

Cloth coffins are similar to wool coffins but are wrapped in soft, natural fabrics instead of wool. The structure beneath is usually made of fiberboard, which is fully combustible and cremation-friendly.

Cardboard Coffins: A Practical, Eco-Friendly Option

Cardboard coffins are another excellent choice for cremation. They are made from fully recycled wood fibers, without any chemical treatments or bleaching. Even the adhesives used in their construction are natural and starch-based.

Though they may not be as ornate as wooden or wicker coffins, cardboard coffins are sturdy, biodegradable, affordable, and well-suited for both cremation and green burials.

Honoring Your Loved One with the Right Coffin

Choosing the right coffin for cremation is an important part of honoring your loved one’s life. Whether based on religious, cultural, or personal beliefs, selecting an appropriate coffin not only ensures a respectful farewell but also provides a sense of closure during a difficult time.
