Did my first fire of a RMH. I build glassblowing furnaces so I have a background using refractories. I used 2300 firebricks for most of it except where the raw wood goes in. My thinking was more insulation between the fire and stack the hotter it will be inside = cleaner burn. I’ve only ever seen one run on YouTube so I’m not sure how much smoke to expect during lighting and shifting of material but there was a lot. At my cleanest burn there was still visable smoke, much less but still there. Is that normal? Should it be 100% clear?
