What is a common characteristic of a crematory?

A crematory is specifically designed for the process of cremation, and its most defining feature is the presence of a furnace or retort. This specialized furnace is engineered to reach the high temperatures necessary to reduce human remains to ash. The design focuses on the safe and efficient operation of this process, ensuring compliance with health and safety regulations.

While burial facilities focus on interring bodies, a crematory has no such function. Although it can be part of a larger facility that might include spaces for memorial services or mourning, those are not inherent characteristics of a crematory itself. Thus, the presence of a furnace or retort is what sets a crematory apart as a dedicated facility for cremation.
