Looks great and 30”” inch is a very sensible size.
I can’t quite work out if you cast your dome around the floor bricks, if you did... did you leave an expansion gap?

Good job, you’ve obviously been researching your build well. I’d guess about 4 x more time spent on researching than actual building, all part of the fun. But i’d Also bet around 10 x faster than a brick build.

The dome came out well so I moved onto the vent. I have a heat break between the dome and vent which I filled with ceramic rope and vermicrete. I cast the vent in place against the dome because I wanted to keep the entry as shallow as possible which meant the casting had to go over the dome so the base plate would fit, sand was used between the dome and the new cast so I could lift it off and remove the form work and sand then put the vermicrete over the dome before lifting the vent into place again. I am using a 150mm internal twin wall flue, and mounted to the vent using a base plate, I set the threaded rod into the cast so the base plate could be bolted in place later. I tried to keep the entry to the oven shallow and get a inverted funnel upto the chimney.

30" cast corner build UK
Hi everyone, I have been reading this forum for a while getting tips and ideas and looking at all the great builds for inspiration. I am building an oven which is 30" internal in a corner position, I have done the curing fires now plan for first pizza this week.
Started off with a 5" concrete foundation, then dry stacked blocks and concrete/rebarred every other hole. 4" thick slab on the top. Then the floor, 3" of calcium silicate board then 3" firebricks. The dome was cast using a castable refractory over a sand mould, I had heard people saying it was hard to work with but I found it not too bad, just dont mix up too much at a time, I had a little slumping at the bottom but apart from that the casting went well. I left it 24 hours then removed the sand and bricks from the inside which was quite a satisfying job seeing the dome.
