Grave wax, also known as adipocere, is a waxy substance that forms on the remains of a human or animal that has been buried underground or submerged in water for a long period of time. There are a number of potential synonyms for grave wax, depending on the context and the specific type of wax being referred to. Some possible options include mortuary wax, corpse wax, taphonomic wax, and burial wax. Regardless of the term used, these waxes can provide valuable insights into the decomposition process and can be helpful for forensic investigators, archaeologists, and others who study remains.
