We just bought a used Skutt ks818 kiln from our neighbor. My wife is into pottery so we couldn’t pass it up. It uses a kiln sitter which uses “cones” to determine when to shut off .. has anyone used this type of kiln for heat treating knives? Either way the upside is that I ran a new isolated 240v 60 amp to my garage .. so I can use it if I get a different knife kiln down the road
