There are a few more, on the left side of my dome, that are just big enough to see fire through when it's raging.
I fired it up again last night for pizza. I wanted to push it one more time to see if I could cause anymore cracks before insulating and finishing it.
My idea is to fill the cracks with hi-temp caulk. It is specifically made for caulking firebricks or fireplaces. It cost about 3 bucks at Lowe's. So I'm gonna caulk it tonight. Let it dry this week. And fire that puppy up on the weekend. Then I should be able to tell you more.
What curing fire are you on?
And how is that mortar doing? Is it getting really hard?
