How to Seal an Urn
Temporarily Seal an Urn
Use PVA or ‘wood’ glue. Most households will have some around. Squeeze 4 drops of glue around the rim of the urn.
Scatter the Ashes Later
To reopen the urn use dental floss to saw through the PVA glue.
Permanently Seal an Urn
Use an all purpose glue that sticks glass, ceramic or metal. You can usually find this sort of glue at any hardware store.
