Not sure how others have finished there dome with stone. One way I thought about was stone setts, because I have them available, for mine that is. If you wanted to go down that route i would suggest getting york stone sett as these split easy into slip or smaller pieces.

Thanks diggerjones. I keep changing my mind between a brick finish and a stone finish.I prefer the look of stone, but brick I think will be more straightforward!

What ever you use it will dead easy after forming the first dome. Mine issue is the slab size beaded for a 42" oven. It works out 42" + 30", so a slab 72" in diameter. I thought I would have plenty of room, but it looks like I will have to corble mine out.

Been on holiday last few weeks so only just got time to start working on it again! Fitted flue to check anchor plate was fixed well enough, then chipped away where I had cemented over the calsil board so I could render the whole dome with a coat of homebrew knowing I now wouldn't be tieing the dome to the hearth. Next job is to put a finish to the top of the brick flue then insulate the dome - will probably light a couple of small fires in a couple of days before I insulate.

On my sixth firing hit 900f, few small cracks in the render letting out steam. Seventh firing at 900f, no more steam, so now to insulate. Only had enough 2" blanket (3m), to do about 65% of the dome, so bought an additional 6m roll of 1", and doubled up to fill in the gaps Tinfoil and wire mesh - I used tinfoil below the blanket and also on top of it. As the blanket I have used is body soluble, I wanted to minimise damage to it from a) any steam being released from the dome and b) and moisture from my upcoming vermicrete layer. Worse part of the whole build so far was the first attempt at applying the 6" up of vermicrete. Took a while to figure the best way to apply it and the best consistency, wasn't too bad in the end. Gazebo off to try and get as much sun and wind on it as possible to dry it out. Will apply another layer next week.

Looks hugely tall, until you look where the floor level is ! Are you enclosing it or rendering ?

I think the size of the entry arch makes it look taller than it is, luckily the inside brick course which meets with the inner arch brings the internal entry down a little. Original plan was to enclose, but going to render now instead. Considering a mosaic cherry blossom tree pattern, but not sure I can handle how long it is likely to take!

On a different note, been looking at some of the finishes on the Forno Bravo forum. There are several builds which have finished the blockwork up with natural stone, can anyone advise if this is likely to be individual pieces of stone, or cladding/slips? I will probably enclose my done when complete, and would like the entire oven finished in natural stone, just not sure I have the skills to lay, or the money to purchase, that much stone, but would happily finish in slips if it was feasible. Thoughts? If the outside of the dome is as neat as the inner it will look great. not sure what to finish mine with either it will be paint,brick slips or ceramic tiles (mosiac)

Keep changing my mind on dome and surround finishes. At the moment mosaic on the dome, and black limestone bricks for the surround...likely to change though!

Just a word of caution regarding mosaic; there are examples on here using pre-cut mosaic tiles available on sheets, highly recommended, I didn't go down this route, and while I'm happy with the look (see build thread below) it took simply ages and I never want to see another tile cutter !

Haven't had much time to work on the oven recently, however, an update: Another curing fire to help dry out the first layer of vermicrete. First ever pizza out of the oven was cheese and bacon for Miss bento! Final vermicrete layer went on. First note: surprised at how good the pizza tasted. Regardless of all of the positive quotes, I always had the feeling it would just be a 'slightly better' version of a standard conventional oven pizza - I was very wrong! Second note: at the beginning of the first ever application of the vermicrete, I decided this was only ever going to be a structural layer, which would have some small insulation benefits, rather than the other way around. Each (approx. 15mm), layer took a full 6 to 8 hours to apply - maybe the thinness of the layer made it more difficult, I'm not sure. After the first layer had dried, I was getting very little heat to the outside of the vermicrete (this is with using 50mm of ceramic blanket), so was happy to only apply one more thin layer. On top of each layer, I lightly sprayed with water, took a handful of cement powder, and 'blew' it on to the vermicrete. This has added an additional durable shell to the dome. I know this won't aid the insulation properties, but as said previously this shell is more to protect the blanket underneath. Next job - final render. Q. I know k-rend is the preferred choice, but has anyone used weber monocouche as k-rend is not available locally for me?
