Irondragon Forge ClayWorks Posted February 18, 2023 Share Posted February 18, 2023 My bottom blast coal forge works well with coal and coke. The fire pot is 10 cm (4in) deep. Quote Link to comment Share on other sites More sharing options...

To create a neutral/reducing heat, ~4" of coke under your work and 2" above will work, no matter what kind of forge you have. If you use coking coal, you should only have coke in your firepot, not uncoked coal. Quote Link to comment Share on other sites More sharing options...
