Hello everyone. Im very new to blacksmithing, as in I've been "making knives" for roughly a month now and im having an issue with my firepot. I burn coke and i have a really big issue with the bottom layer of my coke becoming coated in ash and creating alot of clinker. This in turn seems like it causes me to use much more coke than what i believe is necessary. The walls of my firepot are only ~2.5 inches deep and i do have a clinker breaker but it is recessed below the rim of the hole cut into the bottom of the firepot, and i do not have any type of a grate covering the hole. I can get metal hot enough to forge but coke consumption seems to be an issue...ideas??
