Matt's WFO Build

Don't worry Matt. Wait until it cools and you'll see the crack will close up again. I think that will be your one "big" crack and you'll never see it that big again for a couple of reasons:

1. You will get a few more hairline or even more invisible cracks when your oven is finished "curing" at the 700-800 degree range. I found that my top-to-bottom crack actually got smaller once I got to full oven temps a few days later and I think it's because the dome expands better and more evenly after all the hair-lines and heat-stress points figure out what the want to do. The bigger crack will always be the ovens 1st expansion area but that's all it will be and you don't have to think of it as a "crack".

2. Your insulation layer will "seal" it up.

If you see no smoke which you didn't, your good. I cut a swath of my FB blanket and laid it across my ovens crack and after a big smokey fire...ya, with my critical eye, I saw the faintest whisp of a Grey streak the next day on the blanket. I put some more Refmix on it, put on my blanket and its fine.

You're doing a great job, don't worry about the crack. -Dino

Joe thank for the picture of your crack it does look a lot like mine. You know now that I am reading these sentences it is a real good thing we all know what we are refering to as in a different context this would just be wrong.

I have another question for all you experts out there. Has anyone covered the fancy high heat insulation with a layer of regular old fiberglass insulation? I was looking at the temperatures of the dome and under the insulation the dome surface was about 300 degrees. On the outside of the insulation it was 75 degrees. I was wondering if filling up the space between the 2 inch layer of high heat insulation and the wall of th enclosure would be a good idea or a bad idea. Any thoughts would be appreciated.
