I am using coal (I already have a forge, but I found this and thought it would probably work better, current forge sorta runs but doesn't work that great and is makes clinker like no tomorrow). Thank you for the advice, this is really helpful. I think I will make a side blast, and clay over the bottom (I had an idea of what I was going to do, but just wanted advice of those more knowledgeable than I) with cat litter.
Thank you for the advice!
