Earth Oven Build

  • Come along to the amazing Summer Moot (21st July - 2nd August), a festival of bushcrafting and camping in a beautiful woodland PLEASE CLICK HERE for more information.
I've found straw makes it much stronger - there's a lot of people that like a pure clay oven and others that think straw makes it stronger and less likely to crack. My current oven has a small amount of straw in the thermal mass and seems to be fine.
 
I have half a tub of refractory cement I maybe able to squeeze into the car if you think your struggle .

Presumably the straw will absorb some of the cracking and we can build the heat up over a day or so to get to pizza/ bread heat? Or do you just fire it hot straight away?

"The solid geology is largely masked inland by a capping of glacial drift deposits of the Pleistocene period, approximately 18,000 years ago, exposed as boulder clay around Kenfig, Maudlam and inland of Sker towards Parc Newydd farm."

Clay is mixed with sand, the more sand, the less cracking. Too much sand and the dome collapses. You're aiming for 1:3 clay/sand ratio. Straw helps prevent can cracking but we're only building a simple oven so I wouldn't worry too much!
 
I was telling the landlady at our local- they specialise in locally shot food, beautifully cooked (but not at my budget unfortunately ;) ) so she's asked for loads of pics incase they decide to put one there and I want to try sell the idea to our local meeters too since HS2 wil be demolishing part of it anyways... so I'll hopefully get a few and paste em up :)

:/ not so good. What is the grid reference for your area?

I'm sorry you feel that way, we're very rural and have many local food traditions- the farmers often supply the pub and its done with respect. Or is it the HS2 that the :/ is for? Both areas have strong clay underfoot and would be ideal :)
 
Hs2 - where abouts does it run through?

sorry lovey, misunderstood ;) its near belfry golf course, w midlands :) The meet site at OS map ref' SP189962 is affected. The link to the Woodland Trust map of affected ancient woodlands is here- North Wood is just to the north of the HS2 junction with the M6 on the map.
