That was so neat to see, thanks for posting that process. Where did you get your fire cone?
https://bestbiocharkiln.com/ you will need a rivet gun. It was kinda a pain to get it together. I’m not sure how long it will last. Going on a year now.
I’ll probably mix up some fire concrete and use that as the shape.
You could probably use any fireplace in the shape of a bowl. No holes.
