What i'm particulary confused with, is the fire cement... In italy u just buy a bag of firecement powder where u just add water...

Hi Pietro,

I'm a newbie too so I don't claim this knowledge myself, however I came across a couple of postings by more experienced members under the tapered brick section which referred to a mix as follows:
"the tried and tested homebrew mix is. 6:1:1:1 sand,cement,clay,hydrated lime.
use something like and icecream tub to gauge the measurements.

Good luck with the oven,

Stephen

thanks stephen,
do u know how much fire clay is needed?is 1 25 kg bag ok?

Hi Pedro, The amount of fireclay depends firstly on the size of your oven. For a 90cm diameter oven, if you fully taper your bricks you will need less 'home-brew' and you might just get away with one 25 kg bag of fireclay. If you are only partly going to taper or just bolsert your bricks in half ( as Cannyfraddock does and it is a lot quicker) , then you'll need 2 bags. Cheers RD

Thanks rd, i just have another couple of questions ?
Is the clay the one that is on kilnlinings website?
And what about this other mix (just to confuse me even further) with grog and cement fondu?
Thanks

[rokdok]

The fire clay is indeed the one on the kiln linings website.
I don't know what grog is - I suspect it may be the same as home-brew. I don't know what cement fondu is either I'm afraid.
You won't go far wrong with the 6:1:1:1 mix.
General rule is that use the home-brew for everything that is in contact with a firebrick. Cheers RD
PS don't forget the forum discount with Jewsons.

[pedrosanna]

Thanks RD, i found this "grog" wich is basiccaly fire brick powder in some othe posts, i'll go with std mix aniway. I tought that jewson was still more expensive even after discount or is that just for some products?
Thank u

[rokdok]

Pedro , the ballpark discount is about 30-40%. I've just had a look but I didn't keep any receipts. You don't get a discount on everything and it varies . I think its up to 70% on the ply for box work for concrete. The vermiculite is particularly good value. Good Luck RD

[pedrosanna]

Thanks again RD!!
I owe u a pizza

Hi there I used grog and fondue cement for my oven this is a full belt and braces mortar but not for the amateur I can tell you that ! If you have never worked with any form of mortar mixes before then my advice to all is to stay clear. On the other hand if you have experience or like a challenge then this stuff is fantastic the grog is ground up firebrick available in different granular sizes I used 0-2mm so your basically filling the joint with firebrick. And the grog is a high heat cement that is more than capable of taking the temp from these ovens and sets like rapid cement which makes for easy brick setting I didn't use any forms at all for the dome just the it tool until the keystone! I liked the fact it was a "just sand and cement" mix 2 parts and the water

[pedrosanna]

Thanks for the advice Leethelcd
I'll stay away from it then!!

G'day

There are 2 caste ovens in my neck of the woods which are made of ciment fondue and crusher dust as the grog. Crusher dust is the dust and fine particles left over from crushing basalt for road base. The same mix is used for casting industrial cement chimneys in Aust which is where the idea for both these ovens came from.

Hi guys i need some help. I started to build the dome last weekend but i can't cut the bricks (from kilnlining ), i have a 230mm grinder with a diamond disc m.screwfix.com/p/erbauer-sintered-diamond-blade-segmented-230-x-2-5-x-22-23mm/71137?filtered=true
But it just wont cut them, any suggestion for a different blade?
Thanks
