How are bodies prepared for cremation?

There is no particular way in which bodies need to be prepared. However, the cremator cannot burn everything, and can be damaged by certain articles.

Pacemakers must be removed. Shoes, belts and anything else which does not readily burn should not be in the coffin. Any metal found in the remains is taken away and disposed of, large bones/teeth which have not been completely burned are ground in with the ashes and the whole is rendered into a course granular substance.
