i just got done finishing the outside and while taking out the sand that i used as my base to lay the fire bricks for the dome and noticed that in some spots the mortar did not fill in the spaces between the bricks....maybe the sand sucked it in? anyway should i take the time and the right person to go into the empty dome to fill in these spaces with mortar or will it be ok to fire up just the way it is? thanks to all for any information!
