The choice of urn may depend on what the family plans to do with the ashes: If the ashes are to be buried, some cemeteries have specific requirements regarding the type of urn. If the urn will be kept in a columbarium (a building or structure with niches to hold urns), size restrictions might apply. If the ashes are to be scattered, a biodegradable urn or scattering tube may be chosen. If the urn is to be kept at home as a memorial, the aesthetic and design might be a more significant factor. Securing the Urn: It's important to ensure that the urn can be securely closed. Some urns have threaded lids, while others might have a lid that is secured with an adhesive.
