What is a crematory?

A crematory is specifically designed as a facility where the process of cremation occurs. This involves the use of a specialized furnace capable of incinerating human remains at high temperatures, reducing them to ashes. The primary function of a crematory is to provide a dignified means for the final disposition of the deceased, often as an alternative to traditional burial.

In contrast, the other options describe different aspects of funeral service. A building used for holding funerals is typically referred to as a funeral home or chapel, which serves as a place for memorial services and gatherings. A facility for embalming focuses on the preservation of the body prior to burial or cremation, involving the use of chemical agents. Lastly, a location for casket manufacturing is where caskets are produced and does not involve the actual final disposition of remains. Thus, the clear definition and purpose of a crematory align directly with the provided answer.
