Cremation facilities in the USA involve a closed incinerator. A coffin with the deceased is guided into the incinerator on a steel track. A window may be available for viewing. Loved ones later receive packaged ashes.
In countries like India, open air cremation is common. The deceased is placed atop a funeral bier, usually adjacent to moving water, in full view of loved ones. Ashes may be disposed of immediately following cremation.
In the UK open air cremation facilities have been denied.
