What is the difference between cremation and aquamation?

Cremation is a method of body disposition where the remains are incinerated in an industrial furnace often called a cremation chamber or retort. During this process, the body is reduced to cremains that are basic chemical compounds: gasses, ashes, and mineral fragments. These cremated remains will be further processed and pulverized into indistinguishable fine sand like ashes.

Aquamation is flameless cremation where a combination of water flow, temperature and alkalinity dissolves the body and releases the water in the body so that only mineral bone remains. These cremated remains will be further processed and pulverized into indistinguishable fine sand like ashes.
