Cremation questions

Cremation uses intense heat to reduce a body to bone fragments. The body goes into a rigid, combustible container and then into the cremation chamber, where temperatures usually run between 1,400 and 1,600 degrees Fahrenheit. After the chamber cools, metal such as surgical implants or casket handles is separated out. The bone fragments are then ground in a processing machine to pieces smaller than one eighth of an inch. A stainless steel disc or barcode with a cremation number stays with the remains the whole time. Required temperatures vary by state.

The Cremation Association of North America (CANA) says the cremation itself takes from about 30 minutes to over two hours, depending on body size and how much heat is already stored in the chamber. The Funeral Consumers Alliance (FCA) gives a range of two to four hours. Cooling and processing happen after that, so the total time is longer than the time in the chamber. Cremation typically takes place at least 48 hours after death. Ask your provider how long it will be before you get the ashes back, since that depends on the provider and your state.

No. A casket is never required for cremation. Most crematories do ask for a rigid, combustible container, and funeral homes that offer direct cremation must make at least one low-cost alternative container available. The FTC's Funeral Rule describes it as an unfinished wood box or other non-metal receptacle, made of materials like fiberboard or pressed wood. A funeral home can't tell you that state or local law requires a casket for direct cremation. If you want a casket for a viewing, renting one often costs $800 or more. Funeral homes also can't claim that law requires embalming when it doesn't, so ask before agreeing to it.

Yes. There are several ways to do it. A viewing, also called a visitation or wake, can take place before cremation, and families can place keepsakes in the casket. Items that can't be cremated are returned. Some facilities can only hold a limited number of guests. A funeral with cremation works like a traditional funeral, with the body dressed and placed in a casket the family chooses, an open or closed casket, and an officiant. The family decides whether the casket goes into the cremation. A memorial service with no body present can center on the urn or on meaningful items. Witnessed cremation is also an option.

Direct cremation means the body is cremated with no formal viewing, visitation or ceremony with the body present, which is how the FTC defines it. It usually involves no embalming, and the ashes come back in a basic container. Beyond direct cremation, CANA describes cremation with viewing or identification, cremation with a ceremony or service before or afterward, and a funeral service that includes the body laid out by the funeral home, with the family choosing whether the casket and clothing go into the cremation. FCA notes that adding visiting hours, a funeral service or a casket can increase the price substantially. Many families choose direct cremation and hold a memorial service later at a funeral home, place of worship, cemetery or any place that matters to them. Direct cremation is the lower-cost route, but you can still add a ceremony afterward.

It varies a great deal. The National Funeral Directors Association (NFDA) 2023 General Price List Study found a median of $6,280 for a funeral with viewing and cremation, including an alternative cremation casket and urn. A funeral with viewing and burial had a median of $8,300. Direct cremation costs far less. FCA says a reasonable price is about $700 to $1,400 depending on region. A 2016 FCA and Consumer Federation of America report on 2015 prices at 142 funeral homes in 10 metro areas found direct cremation priced from $495 to $7,595. If the funeral home uses a separate crematory, that fee is typically $250 to $400, so ask whether it is in the quote.

How Much Does Cremation Cost? A Guide

Start by asking for the general price list. The FTC says you can get an itemized price list when arrangement talks begin, prices over the phone without giving your name, and a written statement of what you chose before you pay. CANA suggests asking these questions:

• Do you have your own crematory, or do you use another company? Who owns it, and how often is it inspected?
• Are the operators trained and CANA certified?
• How do you track and identify the body from pickup until the ashes are returned?
• Can family members witness the cremation?

CANA also warns against choosing a provider on price alone.

Unscrupulous Sales Techniques in Funeral Homes

The answer is a chain of custody that tracks the remains from start to finish. CANA lists identification checkpoints at removal from the place of death, transport to the crematory, placement in storage, placement in and removal from the cremator, processing at the pulverizer, placement in the urn, and return to the authorized agent. A cremation number is recorded on a cremation log and is often stamped onto a stainless steel disc that stays with the remains, though it may also be a barcode. A CANA blog post on a case study of a cremation gone wrong says every document must identify the remains correctly and that management should perform regular audits of record keeping. If you use a funeral home that sends the body elsewhere, ask what standards the other crematory follows.

Cremated remains are generally white to gray. The processed pieces are smaller than one eighth of an inch, and an average adult yields 4 to 6 pounds. Metal such as jewelry and implants is separated out before the remains are processed. The remains are sterile and pose no health hazard. Water cremation (aquamation) leaves white bone fragments and yields about 32 percent more than flame cremation, so you may need a larger urn.

You have more choices than most people expect. According to FCA, options include keeping the remains at home in a container special to the deceased, burying them in a cemetery plot or on private property with the owner's permission, placing them in a columbarium niche, and dividing them among family members so some are kept and some are sprinkled or buried in several places. CANA notes that columbarium niches may limit the size of an urn and that scattering may be easier with a specially designed container. FCA says an urn is optional, because the cardboard or plastic container from the crematory is perfectly adequate for burial, shipping, storing or a columbarium. CANA's only recommendation is not to do nothing, since a container left unresolved can be handed down until it is unrecognizable and forgotten.

What You Can and Can't Do With Cremated Remains

FCA lists incorporating the ashes in jewelry among the possibilities for cremated remains, along with coral reefs. A memorial reef is one such option. Eternal Reefs says families can mix cremated remains into concrete to form a central piece inside a reef ball, which is placed at a permitted reef site. Families receive two certificates with GPS coordinates. The company says sites can't be chosen ahead of time because permits expire, and a reef can't be retrieved once it is placed. Ask the company for current prices.

Scattering is legal in most places if you are discreet, according to FCA, but the rules depend on who controls the land. The safest approach is to ask permission first.

• Private land: get the owner's permission. California law, for example, requires written permission from the property owner or controlling government agency.
• Cemeteries: FCA says some cemeteries offer sites for scattering, so ask the cemetery what it allows.
• Public land: contact the agency that manages it. Parks such as Lassen Volcanic and Crater Lake require permits.
• Water: federal rules apply at sea (see below).

FCA says remains to be scattered should be processed by the crematory into fine particles.

Usually only with a permit. Lassen Volcanic National Park requires a special use permit and waives the $75 application fee for scattering. Crater Lake National Park also requires a permit and says it is free. Both parks say the remains must be pulverized and scattered. Lassen says the scattering must leave no obvious piles in any one place, and that remains cannot be deposited within 100 yards of a flowing stream, river or body of water. Its page also lists roads and developed areas as off limits without stating a distance. Crater Lake says the ashes must be scattered and not deposited in any type of container, prohibits leaving urns, markers or flowers, and does not allow scattering in the lake, on the shore or inside the caldera rim. Lassen also says it does not promise to treat the site as sacred or keep records. Each park sets its own conditions, so contact the park you want.

At sea, a federal general permit from the EPA covers cremated remains. There is no application or fee. The remains must be at least 3 nautical miles from shore, and you must report the burial to the EPA within 30 days using its online tool. Only readily decomposable flowers and wreaths may go in the water, with no plastic or metal. States can regulate lakes, rivers and other inland waters. California law, for example, bans scattering in a lake or stream, from a bridge or pier, or within 500 yards of the ocean shoreline. Check with your state before you scatter in inland water.

Yes. TSA allows cremated remains in carry-on and checked bags, but recommends carry-on because checked bags get rapid and sometimes rough handling. Carry-on remains go through the X-ray machine. TSA suggests a temporary or permanent container made of a lighter material, such as wood or plastic, so officers can see inside. A container that produces an opaque X-ray image won't be allowed, and officers will not open a container even if you ask. If they can't clear it, the remains can't go through. Some airlines don't accept cremated remains in checked bags, so check your airline first.

The U.S. Postal Service allows it, but only by Priority Mail Express, or Priority Mail Express International for overseas. USPS Publication 139 says to use the USPS Priority Mail Express Cremated Remains box. A 2019 Postal Bulletin notice says customers must use either the orange Label 139 or the Priority Mail Express Cremated Remains box, and that the label goes on all four sides of the shipping container, including the top and bottom. Put the remains in a properly sealed, sift-proof inner container, meaning loose powder can't leak out. Cushion all around that container, and add a paper with both addresses inside the box. If the shipping label might come off, Publication 139 suggests also putting the sift-proof container in a sealed plastic bag labeled with both addresses and the words "Cremated Remains." For international shipments, the inner container must be a funeral urn, and the destination country must allow the contents.

Several do, and some attach conditions.

• Hinduism: Hindus generally cremate their dead. Very young children and ascetics are buried instead. Ashes are often placed in a sacred river such as the Ganges.
• Buddhism: Cremation is common, and practices vary by culture and tradition.
• Catholicism: The Vatican's 2016 instruction says cremation is allowed unless chosen for reasons contrary to Christian teaching. Burial is still preferred. Ashes belong in a sacred place such as a cemetery. The Church does not permit scattering them or turning them into keepsakes, and it allows keeping them at home only in rare cases with approval.

Your own clergy can tell you how your community applies these teachings.

Practice varies, so ask your clergy.

• Judaism: Orthodox and Conservative authorities prohibit cremation, according to My Jewish Learning. Reform authorities discourage it but don't consider it sinful. Reform guidance says a Jewish person's ashes should be buried in a Jewish cemetery. Nothing in Jewish law bars burying ashes, and many Jewish cemeteries accept them, though some burial societies decline.
• Islam: IslamOnline says cremation is prohibited for Muslims, and Muslims collectively are obliged to wash, shroud, pray over and bury the dead.
• Orthodox Christianity: The Orthodox Church in America says cremation is not permitted under canon law. It notes a few rare cases allowed in extreme circumstances after a funeral service with the body present.

Flame cremation has some environmental costs. Crematories release small amounts of pollutants including mercury, often from dental fillings, at an estimated 2 to 4 grams per cremation. Georgia's Department of Public Health says there is no evidence that chemicals near a crematory reach levels of health concern. The Green Burial Council says flame cremation uses non-renewable resources and has some negative environmental impacts, and it does not cover cremation in its standards. NFDA says water cremation uses less energy and produces fewer greenhouse gases than flame cremation. For lower-impact choices, see the green burial guide.

Water cremation, formally called alkaline hydrolysis, uses water, alkaline chemicals and heat instead of flame. The body is placed in a sealed chamber holding about 100 gallons of liquid, heated to roughly 199 to 302 degrees Fahrenheit, with pressure or agitation depending on the equipment. The process takes three to sixteen hours. What remains is white bone fragments, which are dried and ground. The leftover liquid is adjusted to a pH of at least 11 and sent to the local wastewater system. CANA says the process uses less fuel than flame cremation. Those are CANA's own statements.

Sources: CANA

CANA says alkaline hydrolysis was legal in 26 states as of March 2026: Alabama, Arizona, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Idaho, Illinois, Kansas, Maine, Maryland, Minnesota, Missouri, Nevada, North Carolina, Oklahoma, Oregon, South Carolina, Tennessee, Utah, Vermont, Washington, West Virginia and Wyoming. A January 2026 Montana legislative paper lists 28, adding Michigan and North Dakota, so lists differ by source and keep changing. Legal doesn't mean available locally. Ask a provider in your area whether it offers the service.

Often yes, but the cremation comes after the research. Programs such as the Virginia State Anatomical Program and Elon University's Anatomical Gift Program cremate donors once studies end and return the remains. Virginia contacts the next of kin or authorized agent listed on its form, while Elon returns the ashes only to the person named on the donor consent form. Return can take up to five years in Virginia, and Elon says studies usually finish within two years. A funeral with the body present usually isn't possible, so families hold a memorial service with the returned remains. Programs must accept the donor first, and Virginia says a body with organs or tissues removed for transplant, other than corneas, can't be used. Elon's program pays for the cremation, and Science Care says cremation is free for accepted donors.
