In the plastination process, the body is first embalmed in formaldehyde, then placed in a freezing solution, acetone, which replaces the water in the cells. The body is then submerged in a pool of liquid polymer, such as silicon rubber or polyester. The acetone within the body begins to boil and evaporate, and is replaced by the plastic solution. The plastic can then be cured by UV light, gas, or heat, which will harden the body into a fixed shape.

The plastination technique was developed by Dr. Gunther von Hagens in 1978, who obtained three separate patents for his work with plastination. Initially, plastination was primarily used in medical laboratories and galleries, so that students would have excellent visual examples of the human body’s anatomy. However, in 1993, von Hagens formed the Institution of Plastination in Heidelberg, Germany. With the institute, he held a public showing in Japan of bodies that had undergone plastination. More than three million people attended the event.

This event was a prelude to von Hagens’ next exhibit, Body Worlds. In the Body Worlds Exhibit, carefully preserved skinless corpses are displayed in various positions, many posed as though they are engaging in ordinary activities. Though these models of plastination might appear morbid to some, many people find the exhibit to be a wonderful chance to study the inside of the human body.

Today, plastination is a common technique and an excellent tool for educators. Students in middle schools and high schools are often shown animal organs that have undergone the process of plastination; plastination is also commonly used on animal specimens for veterinary schools. Compared to the “plastic coating” method of the past, specimens that have undergone plastination are far more realistic and durable. Since von Hagens’ invention, it has proved to be a valuable technique for education and preservation.

The alternatives, in using video, even 3D are not yet up to the task.

The only hitch I can see is the use of a persons cadaver against their expressed wishes, and I guess at some point in these matters you need to place faith in the system that procured the “examples” to assure you that every thing that could be done, was done.

As for me, plastinate me, save a wasteful funeral 🙂
