I once did three weeks of IT work in a forensic pathology lab.
Spoilered for disturbing detailsThey had a microwave - a regular microwave oven designed for use in the kitchen. They used it for degloving hands. That means they put the severed hand in the microwave and heated it until the fatty layer under the skin softened. That way the skin could be slid off mostly intact. I absolutely would not do this to a living person. It doesn’t seem healthy.
