Temporary Oven: Version Two
December 23, 2016: reducing the height
we took out lots of bricks, including the side and back walls...
...plus three rows of bricks, and put the roof back on
then we put on a second layer of rood bricks...
...and lit a small fire to test the draft (it burned well)
the inside of Version Two -- now it's a flat roof, six courses high
chimney at the front
outside north wall, this time with lots more tie-ins
outside back wall (it collapsed when we took down the first version)
outside south wall -- the most stable
Version Two oven, with plenty of tie-ins
From Yo: We lowered the ceiling by two layers of bricks, and strengthened the wall by inner firebrick wall and outer regular brick wall biting each other. Jutta has been interested in the ceramic fibre blanket for insulation. Letís see what the lower ceiling might do.
Dec.26, 2016: second firing
8 a.m. biggest fire yet, Dec.26 -- planning to test bake bread
spreading out the coals
1 p.m. roasting squash and mushrooms in the embers
clearing out the embers
wiping out the hearth
slashing the loaf
Yo blocked the door opening with bricks, to keep the heat in
very tasty sourdough, 40 mins. at 400 C
From Yo: Rain. Fire started at 8 am. It took many pieces of wood to eventually burned white. We roasted sliced squash and whole mushrooms on a tray with coals in. After that we cleared the oven with a hoe and a ripped shirt-rag. The thermometer read a little under 400 F when I put a loaf of bread in, barely 350F when it was taken out after 45 minutes. Bread was pale, didnít spring much in the oven. Looked to me like a typical winter bread.
Heat doesnít seem to be retained much in this oven even though the outer wall doesnít become warm at all. Maybe a big portion of heat is escaping through the cracks with smoke? Jutta decides to get the ceramic fibre blanket.
