Here is my Build, I have always wanted a Pizza / WFO and have finally started to build my own. I have no experience with brick laying so it has all been a learning curve. I started with building a BBQ and I am now adding the WFO. I'm planning on using a mix of Storage Heater Bricks(40) and some Fire Bricks that I got hold of. I am thinking of getting some more fire bricks to complete the dome, as I don't have enough Storage Heater Bricks to complete a dome.       |

   I managed to get a bit more done over the weekend, Progress was halted when I killed the blade on my angle grinder. A quick stop and B&Q on the way home and I'll try and get some more cut tomorrow evening. Dave |

Finally completed the dome, a little bit of clean up to do. should I light a small fire or just leave it to the the current good weather to dry it out before I start on the insulation?   |

Looking good - it feels good to get the dome finished.
I left my dome for a couple of weeks while I built the outer arch and chimney. I then gave the dome a couple of days with a gas burner sat in there on the lowest I could get it. This slowly warmed the dome through and (hopefully) got a lot of the moisture out. Its no problem doing this with thermal blanket over but I held off the vermicrete.
I finished the vermicrete layer yesterday morning - its amazing how much water it takes!! I used a mix of 10:1 and found it easier to use the wetter it was.
Hope this helps

Looks good Dave. Sound advice from DL. A lot of people advocate starting the curing fires early, but I guess that if it's dry and warm a lot of moisture will come out naturally anyway. DL is right the vermicrete takes a lot of water - and it is very slow to dry out mine took two weeks of warm dry weather. Keep up the good work RD.

G'day
That's a good thing leaving the dome for the wind and the sun to do its thing and dry things out . The "so called curing method. " we often find is more suitable to a cast in a box oven. It certainly doesn't suit a lot of home ovens. Too much extra water involved, they are built in the open and are exposed to the local conditions.
Rather than the term curing its more about drying the oven out . That in itself is hard to tell the outer surface is dry! But how much water is trapped in the inside ? There is no way of telling and certainly no way of measuring.
The water that's still in your oven will still turn to steam at 100 C and 1 litre of water produces 1500 liters of steam. That's a lot of force .
I'm a fan of low and slow heat heat over a small period of time and then let the dried surface that you have made absorb the moisture from deeper . Then do it again with the heat till it goes good .
Charcoal works really well at this because it supplies heat without the flames that can overheat the top of the dome to quickly than the rest and this can contribute to cracks because of uneven stresses.
As for gas alliances in an oven sorry..... Can never think it safe to operate a gas device in an oven that designed to throw the heat back on its internal fires ... That's scary . I like the " Can Do" attitude but not with gas ...... I'd be leaving that to the experts.
If your using v-Crete that's a lot of water , do it in thinner layers and let them dry over time before adding the next.
Sorry I can't offer a more exacting plan , but low and slow heating is definitely the way to approach drying your oven
Hope something here might help
Regards dave

I Completed the outer arch this week and thought I'd have a little fire. I hope to make a start on the chimney this weekend.    |

G'day Dave
Well you certainly got that arch building down to a fine art now that's the third one now on your build. I like the big entranceway way as well it will go a long way to making you oven easy to operate.
Of course I like the flame .... None of us built these thing cause we didn't like a bit of fire! I'm a fire maker as are we all . Just take an 8 yr old and show them how to flash up a fire and get an oven up to temp. Wow it really takes them in,they are truly taken in with the experience and the responsibility.
But , as always take it easy with the flame when you oven is still "wet" flame causes undue stresses. Low and slow, dry before you drive the heat into your structure.
Regards dave
