All things are possible, some things aren't sensible. A bare 'core' will reach 350°c and not much paint will stand that sort of punishment; as for mosaic, I suggest a quick search for my thread on the topic.

Very neat build, thank you for posting 👍🏾

Some may find the recipe a useful guide; personally I wouldn't use oil in the base as it'll burn in a wfo. The link is advertising a related product so I'll leave it for now.

Dry sand will allow you to 'shuffle' the firebricks to get a level base, and facilitate the removal of any that become damaged in use 👍🏾

Fair enough, but doing things twice will always cost more. With you extension in mind, plan where your oven might sit and get the builder to erect it to your specification; voila, a brick wfo in the right place 👍🏾

You seem intent on doing the work twice and the dome is only a component of the wfo build; you'll still need a stand, insulation flue etc so why not go straight for brick ? It's really not that hard and will outlast a composite oven. Source some used damaged bricks as you'll be cutting them in half anyway, don't scrimp on the insulation and the jobs a carrot.

A friend is struggling with a newly constructed wfo from Vitcas in that he cannot seem to get it to a reasonable temperature; compounded by somewhat confusing instructions from the supplier.
This info is coming via another forum so any losses in translation are mine alone.
The oven is reportedly a Vitcas 140, internal: 800mm wide x 1,400mm deep x 400mm high Weight: 500kg
The 100mm diameter flue has a damper and the oven is supplied with a fixed external door which has adjustable vents.
The fuel used initially is kiln dried ash.
Verbal instructions from the supplier do not reference any 'curing' or drying out fires rather "... the manufacturer suggested building a big very hot fire for the first firing."
"Not what the manufacturer says. They say to start the fire and keep the door closed except for refuelling until the oven is up to temperature."
"I've told the manufacturer I'll give it one more try. They asked what wood I was using I told them kiln-dried ash. They say this is no good and suggested I used only kiln dried oak. I now have a load of that and will try again. I've also ordered another metre length of flue-pipe, see what difference that makes. Not much I can do about the diameter."
I have suggested a 'curing' routine but this appears contrary to manufacturers instructions; other than a very small flue as supplied has the collective any thoughts ?

Au-contraire my little reynard, I've been using heater blocks in my wfo for the last six years and they are all still intact and work well. Mine was indeed a budget build but there's no harm in that and I've managed a couple of evenings doing 50+ pizzas.

At 10.4" you'll be just fine; I used angle iron on top of perpendicular bricks to bridge my 'arch' so mine is on 8" and I've never struggled, even with a turkey 👍🏾

Neither, it's the available vertical gap; from the cooking floor to the highest point of the gap into the oven 👍🏾

Your storage blocks will need wetting and you'll need a mask; but that's nothing new 😷

No idea about the block splitter, but just be aware that firebrick is much denser than common brick used in building. I do know that some have used a bolster and lump hammer for splitting so it may work.
As to the heater blocks, lay them on dry sand to aid levelling and they'll be fine (mine are) but for best effect they should be contained either by the oven wall or some other means to stop them moving apart. If they extend underneath the oven wall then heat will leach out so do encapsulate the whole wfo in an insulating layer.
A build thread with pictures is not only informative but may well allow us to correct errors before they become permanent.
Good luck 👍🏾

Seen in the middle at Lidl reasonably priced pizza peels; looked ok for a tenner 👍🏾

The vast majority of WFO's have cracks; you have the opportunity to do something about yours before adding your chosen insulation. A wet slurry of your dome mix certainly won't do any harm to your dome, but carefully staged drying fires would help.
