Cerbu Ulea

I am pleased with this shorty heater you designed, good efficient burns once a day, the wood will last longer than I thought no black smoke even early on  , with on top lighting

hello, I discovered that only the meter that portrudes the roof is 17 /17 cm , the upward chimney is about 190 mm square does that change the math  of the stove? there is no need to go larger , the actual 165 is very  good

hello, about the lighting method, is there a problem I use  1 table spoon of alcohol and edible oil emulsion on a piece of cardboard? kind of a homemade grill starter cube

please comment about the greenish flame exiting at the bottom of the port , sometimes it's blueish.
Could that be ignited CO ?

I found in the ashes a piece of glass that was softened, indicates above 750 celsius , is that too much in the firebox ?

whole rolled oats, ex:

are my preference, in about 4 days I start using the mash in smoothies or in cooked porridge, there is nothing inedible inside , no need to sieve , filter nor decant. Also I use no starter , it sours just fine (will water , leave tap water overnight)

I like this ferment too, I use a gallon jar half filled with  oat flakes and /or wheat flakes, or other cereal , then fill with water leaving headspace, cover with a plate or a cap not tighten, stir daily as some float

I refueled 2 planks a bit too long but it ate them well

2 tons I think its a  fair guess, fire bricks seam heavier ,  3 kilos each?  some in the top bell plus the core , the sand was say 10 buckets, and the old terracotta tiles count I think, is it a good number? It stays warm 36 +  hours this time of year, but one fire a day I prefer now

please help me calculate the mass of my stove , single skin yet, it has aprox. 400 bricks at about 2,7 kilos each , the core has thin mortar but in the bell's walls there is a lot of clay & sand , add also the number of the fire brick in the core , which I did not weigh
