The COLOR CASE HARDENING KIT by PRAXAIR allows gunsmiths to create custom color case hardened finishes on firearms.
The Standard Kit includes all necessary items for color case hardening except for the furnace, which is ideal for those who have their own heat source.
The kit comes with detailed instructions and essential supplies like a large crucible, tongs, Kevlar gloves, a face shield, wood and bone charcoal, filter masks, and an apron.
