L&H Freeze Branding Iron - Letter Set (A-Z) - 26 Iron Set - 1 to 6 inches

L&H Freeze branding irons are made of solid brass to permanently identify livestock by applying extreme cold to the animal's skin. The iron is chilled with liquid nitrogen or dry ice to a temperature of -50 to -100 degrees Celsius, then applied to the animal for 10 to 60 seconds. The cold kills hair follicles, causing the hair to grow back white or light-colored in the shape of the brand.
