If you’re a fan of the TV show Yellowstone, you’ll know the deal – you earn your place on the ranch by being branded. On the show, this means having a red-hot iron pressed into your flesh, leaving a permanent scar of loyalty to Yellowstone Dutton Ranch and its patriarch, John Dutton.
In life imitating art, people are getting themselves branded, but instead of using heat, they are using freeze branding. The branding iron is cooled using dry ice, isopropyl alcohol or liquid nitrogen, and then pressed against the skin to leave a permanent mark.
In 1966, Dr R. Keith Farrell at Washington State University developed freeze branding (also known as CryoBranding) as a less painful way to mark animals for identification. Aside from being less painful, it also produces less scarring than hot branding.
