Contrary to popular belief, the cremated remains are not ashes in the usual sense. After the incineration is completed, the dry bone fragments are swept out of the retort and pulverised by a machine called a "Cremulator"—essentially a high-capacity, high-speed blender—to process them into "ashes" or "cremated remains", although pulverisation may also be performed by hand. This leaves the bone with a fine sand like texture and color, able to be scattered without need for mixing with any foreign matter, though the size of the grain varies depending on the Cremulator used. The mean weight of an adult's remains is ; the mean weight for adult males is about higher than that for adult females. There are various types of Cremulators, including rotating devices, grinders, and older models using heavy metal balls.
