What is a "retort"

Cremation is the process of reducing a deceased person’s body to ash, bone fragments, and dust. It is achieved through a cremation chamber, also known as a retort, which houses an automated furnace designed to withstand temperatures up to 2,000 degrees Fahrenheit. Modern cremation furnaces are typically propelled by natural gas, propane, or diesel fuels, and must abide by stringent air quality standards. The cremation process typically requires two to three hours of time which can vary depending on the body weight, container size, and furnace efficiency. Special caskets designed to break down during the process may be used, or alternatively, a simple and sturdy cardboard box can be provided. The container must be combustible, nontoxic, and strong enough to hold up under the weight of the deceased. This one is located at Mt Hope Cemetery in Rochester NY.
