The word "concremation" is a rare technical term used in chemistry that denotes the process of reducing a substance to ashes by strongly heating in a fire-proof container. The correct spelling of this word is /kɒnkrɪˈmeɪʃən/ in IPA phonetic transcription. It is derived from the Latin word "concrematio" which means "burning to ashes." The word is often confused with "cremation," which refers to the process of burning a dead body to ashes.
