People generally understand what the term cremation means.
When we are asked for a detailed definition, however, we tend to hesitate while searching for appropriate words. You may be asked to explain what calcination is, and to define the difference between cremation and calcination. Although the end results are very similar, some people find the differences in process to be significant. In the calcination process, excess air or oxygen is substantially reduced, thereby eliminating direct flame contact with the body. In fact, the body and container never break into flame during calcination.
