    This has ben inspired by a young man as a family home work project.
    we have to make something for the house or garden it must have a element of recycling and must be as much as possible carbon neutral in it's use why do they do this to me :crying:
    we were going to make one but now I have ben press ganged in to it pizza oven probably going to be one of the bigger project's at school.
    I have cement and a bag of perlite and bentonight clay and some sand in the garage we have wood laying around
    we have a week to complete.
    photographic evidence will be ok apparently and the peza party is on Saturday of next week
    luckily I am working from home this week getting in my own bead every night
    whach this space (y)

    only problem I see is how can burning anything be carbon neutral?

    Burning quick growing wood (such as willow and birch) is said to be carbon neutral. Depends on how much you burn and how often I suppose. Plant a tree to offset what you burn :)

    wood only releases the carbon it has absorbed during it life cycle

    same could be said of fossil fuels Bill, not a good argument in my book, still the School may see it your way.

    Not sure what bentonite will be like but you need to add some sharp sand to your clay mix.
    Mix up 3 samples, about the size of half a slice of bread but twice as thick in the following proportions ;
    SAND CLAY
    25% 75%
    50% 50%
    75% 25%
    Mark two lines on them 50mm apart and then leave them somewhere warm to dry. Once they are completely dry, measure between the two lines and see which one has shrunk the least, this is the mixture that will give the least amount of cracking when the oven is fired up.

    I'd echo jockaneezer's comments - clay can be a bit of a bugger when trying to fire it. There's all manner of faff that goes into pre-heating ceramic pots before they're baked hard, and there's all sorts of stuff you can mix into big clay objects to prevent them cracking too easily. Might be worth a quick look on YouTube even though it's just a project. Good luck with it anyway.

    I went to my old yard and got some engineering bentonight I am allowing it to hydrat over night to the clay slurry I will aide
    slurry 25ltr
    perlite 100ltr
    silica sand 50kg
    cement 25kg
    this might be to much materials but just want one mix job done
    I am making a refractory cement it's a tried and tested mix
    I will post some picks later
    I dose not suffer to much Frome cracking I have ben told
    before I fire it once set I will dry with a paraffin tilly lamp then tea candles for three days
    it will then be fired only with the materials I have made with and very slowly bring it up till it is very hot
    it will have chicken mesh thru it and coped fibre glass and will be abut 4" thick
