Soap Mummies
OMG! They’re a Thing!
Mummies are a specific kind of fossil. A mummy is a kind of preserved fossil that can retain the appearance an organism had in life long. Mummies can be made on purpose due to unique burial practices and mummies can also occur naturally because of special environmental conditions.
Natural mummies occur most frequently in environments that are exceptionally cold and/or dry. The most well-known regions in which natural mummies occur include Egypt, east side of the Andes Mountains in South America, and the Tarim Basin in China.
Mummies that occur in the cold/dry climates of the world are usually desiccated (dried out). These mummies have lost all of their body moisture leaving only the tougher, more fibrous parts of the body, especially, the hair, teeth, bones, sinews (tendons and ligaments), cartilage, clothes, and grave goods (mementos left in the grave with the body). Occasionally, a well-preserved mummy will even have remnants of skin and fur.
The entire previous definition applies to the most common form of mummy, but there is another kind of mummy, one that is more gruesome (if that were possible). The most disturbing kind of mummy to look at, in my opinion, is a SOAP MUMMY. This is a human corpse that has turned into soap!
Mummies that occur in cold/dry climates go through all the normal stages of death, but, due to an extremely cold and/or dry climate, the putrefaction process (decomposition or disintegration of proteins into simpler compounds through the action of microorganisms) (1) is slowed to the point that bacteria can not thrive enough to break down the proteins effectively.
As the microorganisms struggle to break down the corpse, fluids continue to drain from the body. If the fluids leave the body faster than the bacteria can break down the proteins, then parts of the body become “preserved”. If this happens, a mummy will be created. The degree to which this happens is the main factor in determining the quality of a mummy specimen. Savvy ancient humans became aware of this process and began making mummies on purpose.
Soap mummies, however, go through an entirely different process. They are created through a chemical change called saponification (the word literally means "turning into soap". Therefore, soap mummies are created when microorganisms are halted in the presence of saponification (fats are turning into soap) in the presence of alkaline water (2). Kathryn Meyers Emery, Ph.d. who wrote “The Soap Man and Lady Revisited”, verified this in detail in the Word Press article “Bones Don’t Lie” (3).
This mind-boggling postmortem predicament only occurs to a corpse under specific circumstances. Unlike more traditional mummies, the environment necessary to make a soap mummy must be wet and warm. The high water content of the the soil must have an unusually high alkaline ph. level AND ALSO an unusually low oxygen level.
Due to the uneven nature of soil chemical and moisture content, evidence of saponification can be found on many corpses, but usually only in small amounts. When a tiny amount of this process occurs, it has been referred to as “grave wax”, “corpse wax”, or “adipocere” (4). The saponification process rarely occurs to an entire corpse, therefore true "soap mummies" are quite rare.
The Smithsonian Institute is in possession of a famous soap mummy called The Soap Man. This soap mummy was discovered in 1875 near Philadelphia, Pennsylvania. It is believed the person died and was buried around the year 1800. The skin on his lower face and the rest of his body have become saponified, but the hair and skin on his upper face have completely decayed, leaving nothing but skull (5). This is evidence that the top of his head was elevated above the water line, so the portion of his body above the alkaline water (the top of his head) decomposed normally, while the rest of his body (submerged in alkaline, low oxygenated water) was saponified.
The Mutter Museum is the home of the famous Soap Lady Mummy. The Soap Lady was buried around 1830 near Philadelphia, Pennsylvania. The woman whose body became the Soap Lady, is thought to have be less than 40 years old at the time of her death. Because the mummy was discovered in 1875, this places her interment into the soil around 1830. This means the natural process of saponification took less than 45 years. Further, unlike the Soap Man, whose organs did not saponify, the Soap Lady has completely turned to soap! (6). This may be due to the presence of a bacteria called clostridium welchii (which can cause gangrene and other infections that lead to death) that helps trigger the presence of corpse wax (7).
A soap mummy is quite stable (as other forms of soap are) and can remain intact unless broken or dissolved.
