burning result of fire basket on UDS.
Please note that I add 1" lining by ceramic clay/mud.
I fired the charcoal before the mud is dry.
Fire basket and ash box. All ash does not fall into the ash box.
Ash box also forms an air pass with fire basket.
This way all fresh air pass through charcoal only.
No excess fresh air by-pass to smoker and lower heat efficiency
Also no excess fresh air by-pass, less convention, and more juicy meat.
I burnt this UDS yesterday.
It kept at 105C or 221F for most time. only occassionally 104C.
It burnt just about 1.5 LBS of charcoal
Next step I will add 1" lining around walls and botton by ceramic clay mud, and will wait 2 weeks for clay mud to dry naturally. Then I will fill the smoker with branch/chip/chunks, and then seal it on top by mud. and make 3 holes on mud seal for ventinlation.
Finally will start fire from bottom. I expect to burn for 1 to 2 days and maximum temp 600-800C or 1100F to 1470F. This will transfer clay to low temperature pottery.
By then I will have my kamado!
