I insulated my home made arch with firebrick last year. I can't believe how much of a difference it made to my boil rate! All that heat going up into the pan instead of burning my legs through my pants
While I was boiling this year it worked great, but as you can see in this video. When I moved my arch back into storage I realized the mortar had all dried up and broken causing a few of my fire bricks to fall out (and the rest aren't far behind).

I did use fireplace cement made for fire brick to install everything but clearly I'm not doing it right. Does anyone have any suggestions for how to re-install them so they don't fall out? Am I going to need to add some angle iron or something to hold them against the wall?
Thanks!
