I have a new A6 clay/graphite crucible to replace the welded steel pipe one I've been using in my Gingery style blast furnace for the past couple of years. I also recently constructed a propane burner for the furnace to make tuning the temperature a little easier than with charcoal, as well as to leave more space to work in the furnace. Can someone share with me their procedure for initial anealing of such a crucible? I'd hate to crack it on the first try!

P.S. I'll be forging some purpose-made tongs for the crucible to handle it before I stick it in the furnace.

Thanks!
