Cremation urns made from metal and stone are best for burying ashes, because these materials are strong enough to resist collapsing under the weight and pressure of soil. Urns made of wood may still be buried if the urn is enclosed in an urn vault designed for burial, but metal and stone urns are preferable because wooden urns may degrade over time from moisture. Biodegradable urns are also ideal for burial, because they are designed to break down in soil and water in an eco-friendly manner. You should decide if you prefer to bury an urn that will last for decades or centuries, or an urn that will break down and leave no environmental impact.
As a rough estimate, someone who weighed 200 pounds while alive would have about 200 cubic inches of cremated remains. One pound of a person's weight generally equals one cubic inch of cremated remains. However, a more precise estimate can be found through our urn size calculator, which takes into account age, height, gender, and bone mass to calculate ash volume and suggest a recommended urn size.
Vase-style urns seal with a threaded closure on the lid, while box-style urns seal with additional screws that hold the lid in place. Keepsake urns and cremation jewelry urns will also have a type of secure lid that seals, usually featuring a threaded closure. These urns will all safely hold ashes without opening, but for further peace of mind, you may choose to additionally seal a lid with silicone, resin, or epoxy glue. To permanently seal an urn using glue, only a small amount of glue is necessary.
You can bury your loved one's ashes in a cemetery. To bury cremated remains within a cemetery, you will need to purchase one of the cemetery's burial plots. Burial plots for urns will typically cost less than burial plots for caskets because they take up a smaller area of land. Some cemeteries will have designated areas for urn burial, such as urn gardens, that are separated from the area for casket burial. If you are burying your loved one's urn within a cemetery, you may also wish to purchase a headstone to mark your loved one's resting place.
Cremation does not require blood or any other fluids in the body to be drained. However, if a viewing or open casket funeral is planned for your loved one prior to cremation, they will need to be embalmed first, which involves draining blood from the body and replacing it with formaldehyde. This process helps preserve the body by slowing the rate of decomposition. Embalmed bodies can still be cremated, but an embalming is not necessary for cremation. If your loved one will not be viewed post-mortem, you do not need to have them embalmed.
A cremation container is a combustible box or casket used to hold a person's intact body before cremation. When cremation occurs, the cremation container holding the body gets burned in a cremation chamber. After cremation, when a person's body has been reduced to bones and ground into small particles resembling sand, an urn is used to store the cremated remains or "ashes." An urn for ashes can be a temporary holding container while the ashes are transported for scattering, or it can be a permanent urn intended for burial or decorative display.
For couples that wish to both be cremated, companion urns allow their ashes to be stored together after death. The ashes of an average adult typically require about 200 cubic inches of space, so companion urns have a capacity of at least 400 cubic inches combined. They can have either separate compartments or a single large space to accommodate two or more cremated bodies in one urn. When placing the remains of multiple people in one companion urn, you can choose to keep the ashes separate in bags or pour them together into the urn, mixing the remains.
It is not bad luck to keep ashes in the house, and no bad luck superstitions about this exist. In fact, many families find comfort in having their loved one nearby. Apprehension or hesitation about keeping cremated remains at home is likely a cultural influence from Catholicism, which teaches that if a Catholic is cremated after death, their remains must be treated the same as an intact body and buried.
Scattering urns are designed to allow easy dispersion of ashes in the air or water, and have different shapes depending on the type of scattering. They can be made from biodegradable materials like paper and fiber or durable materials like wood and metal. If a scattering takes place on land, an appropriate scattering urn may be a scattering tube that features an easy-open hole or removable lid to aid the pouring of ashes. Water scattering, where cremated remains are released into the water, can use either scattering tubes or biodegradable urns that are directly placed in the water to sink.
If a cremation urn has not been permanently sealed with glue, it can be opened again by unscrewing the threaded closure or removing any screws holding a lid in place. An urn may be opened to transfer the remains into a new urn, perhaps because the current urn is a temporary container or a new urn has been chosen for the ashes. An urn may also be opened to remove the remains for other final disposition, such as scattering. However, a cremation urn does not need to be opened for maintenance or cleaning, and does not need to be replaced unless the urn is damaged. Opening an urn can introduce moisture to cremated remains, so it shouldn't be opened unless necessary.
Wood cremation urns all use durable hardwoods, so the "best" wood for urns is simply a matter of personal taste and style. Different kinds of wood offer unique grain patterns and colors, and cherry, walnut, and oak are all popular picks.
A wood urn, metal urn, or any type of urn should have a size that corresponds with its intended use. If a person's complete ashes will be stored within one urn, the size of the urn should be large enough to accommodate the full volume. A general guideline is to assume that at least one cubic inch of volume will be necessary per pound of body weight. For example, a person who weighed 125 pounds would need an urn with a volume of over 125 cubic inches. Wood urns also come in keepsake and medium sizes for holding a portion of ashes, and extra-large and companion sizes for holding more than 200 cubic inches of remains.
After cremation, remains are carefully removed from the cremation chamber and transferred onto a cooling tray. The remains are processed to remove any metal fragments that may be present, if for example the deceased had a surgical implant. When only bone is left, the fragments are processed into sand-like particles using a machine called a cremulator. These "ashes" are returned to the family in an urn or other container.
A cremation urn can be displayed at home in any manner you feel appropriate. To prevent any damage to the urn, you should ideally find a visible location where the urn will not be disturbed, such as a mantle, shelf, or dedicated memorial space. However, some families without pets or children prefer to keep the urn on a well-used surface, like a coffee table or dining table, to keep their loved one close to them. In either case, personal touches like photos, candles, or flowers can add to an urn display and create a thoughtful tribute.
Most wood urns are box-shaped and have a removable bottom panel that is held in place via threaded screws. After the screws have been tightened, some people may choose to add glue to seal where the edges of the bottom panel meet the urn, but this is a matter of preference.
Most metal cremation urns are vase-shaped with a threaded lid, which means that the lid uses a twist mechanism to open and close. To open a metal cremation urn and remove the lid, unscrew the top lid counter-clockwise.
Metal urns are one of the most durable types of cremation urns, and can last several decades to centuries. These urns are usually vase-shaped and made from metals such as brass or pewter. It takes extreme force to damage the structure of a metal urn, and if one is buried underground without an urn vault, over time the urn risks collapsing under the weight of soil. Like other metal objects, metal urns can also be dented or scratched with improper handling, but these visual flaws will not affect the strength or function of the urn. In the Light Urns offers free urns for ashes that have suffered minor aesthetic damage in our warehouse and cannot be sold in perfect condition.
A loved one's cremated remains may either be divided among family or kept together within one urn. Some families find comfort in sharing ashes amongst themselves so that family members can keep their lost one close, while other families feel it's more respectful to keep the ashes intact so that their loved one can remain whole. Deciding whether to divide cremated ashes is a personal choice that varies by family, and both options are respectable ways to honor a loved one's memory. Ultimately, the decision should honor the wishes of the deceased and provide peace to those left behind.
To choose a cremation urn, you should consider how much volume you will need, along with how the urn will be used. If the urn will be used to hold an adult's complete amount of ashes, you will likely want a standard-sized urn, which is designed to accommodate most adults.
Our urn size calculator can help you estimate the volume of your loved one's cremated remains and determine what size urn may be appropriate.
Once you have an urn size in mind, you can select an urn material based on the urn's intended use, such as whether it will be displayed, buried, or used for scattering.
For every urn size and urn material, there are beautiful urn options to choose from, and you can pick a design that speaks to you or that fittingly memorializes your loved one.
Cremated ashes are actually bone fragments that have survived the cremation process. During cremation, heat burns away any decomposable material, so the remaining bone fragments are sterile and can last indefinitely in an urn if stored properly. A sealed, dry urn can preserve your loved one's ashes for eternity. Ashes will also remain intact outside of a container if they remain moisture-free, so it isn't necessary to have an urn immediately once you receive your loved one's remains from the crematorium.
