I successfully bisque fired some wild clay pottery in my solo stove!
I have a bonfire 2.0 with a ceramic wool jacket around the outside and pointed some fans at the base. I fueled it with hardwood charcoal. My pyrometer read 925C ((700F) in the center and held that temp for about an hour and a half.
This clay was pure clay with no grog or anything in it so there were a few casualties but it worked much better than I hoped! My next batch will have quite a few additions to help it survive this firing process
I also raku glazed a small bowl with a homemade glaze made from slip, borax detergent, and copper carbonate (I made this from root killer (copper sulfate) and baking soda). It didn’t turn out as well as I would have hoped, the borax was still grainy and the glaze was watery but it still worked to some extent! I think I didn’t have it evenly heated when I pulled it out
