Irish Build
 
6 Attachment(s)
So got oven built last week, wont bore people with base construction as we all know a slab of concrete is not most exciting part.

Ok so i ordered 180 bricks for a 90cm or 36inch oven.

only used about 120 in total.

about 40 for floor (cut to fin inside walls)

and 80 for down ( i know i should have tapered bricks that way be better joints and would used more bricks)

all bonded with the home brew 4:1:1:1 mix

It started hammer down rain near end so foolishly rushed the last 3 chains and they look god dam awful

took time do part over the arch but looks awful. its insdide and wont be seen anyway more i know its there

left dry for 4 days under a tarp.

then had candles in it for 48 hours solid.

yesterday started curing with small fires but timber i think must have been damp as got lot smoke and soot inside.

Also fire got fairly hot 2 hours into it when i went for a walk and when came back there were lot cracks, 1 of which is leaking at the join between 2 cracks.

there then came few more that look be following brick joints.

also one over arch so not very please as fire must got very hot.

kept it going for 5 hours then left embers in it over night with door half blocked up to keep heat in and the cats out.

here is the cracking

after 3 -4 hours steam and damp was evident around cracks but no smoke came out of them

seem sound hollow to tap.

also sonly one is smoking, the one marked in blue marker.

looks like its all around the area where the 3 last bad chains were

brick cracking going vertical is on the right hand side when look in door.

blue marker is directly at the rear top when look in door and other one is over arch

the circualar one is evident from top

i plan on wrapping it all in 3 iches of ceramic blanket (equiv to 6inch vermiculte concrete per fono build pdf) and the stucco it. i had planned build barrel tye oven thats why my base is too narrow and have try squeeze outer layer in, going to be tight though
