Crack

Re: Crack

I got a very small hairline crack in mine when I first fired it, while its not a problem structurally it bugged the hell out of me.

I racked out the joint to a depth of 5mm, moistened the joint and refilled it, it hasnt reappeared.

Leave it....a mortar parge wont hold.

After the massive fire. The dome itself was fine but I got a crack in my outer arch.
Maybe 1mm between a brick on the left side of the arch and it's mortar joint on the uphill side. What I mean is, the mortar as a mass is intact but it's as if it has pulled away from the brick to leave a crack there.
Seems still structurally sound but it's not nice to see. Like a zit on an otherwise nice face.
Should I slather more mortar onto it or leave it be?
