Hello
I need some advice on how to fix cracks please.
About 10 days ago I completed the insulation layer on my oven (4 inches of vermicrete). Prior to that I had fired the oven twice and it went well ? no cracks. So after leaving the insulation layer to dry for 10 days, on Saturday, I made a fairly big fire and it went ok. The oven went all white inside and was still steaming in the morning and warm on Sunday afternoon and again no cracks.
Last night I repeated the treatment but I think I have exaggerated. I got a crack on the top of the dome ? from the flue to the centre top - with smoke coming out of it. There is also a smaller crack from the centre top to the side ? but that looks less concerning as it?s smaller and it does not smoke. Please see pics. I have some more pics in my album :

I can?t see any cracked bricks in the inside, so I suspect there is no structural damage, but as you can see from the pics I was not very good in properly filling the gaps between the bricks with mortar.
What it the best way to fix the crack and should I fill the gaps in between bricks with mortar in the inside?
Thank you
Andrea
