I am building a Mattone Barile oven I’m at the point of laying the firebrick on the sand. Do I mortar the joints when I am done. In section 7 of the instructions it says “DO NOT MORTAR fire bricks” then it says “Do that in step 48” but there is no step 48. What do I do?
I asked the same question earlier this year. The upshot: no worries, but definitely no mortar.
Here’s a link to the earlier response:
Good luck with your build!
Don’t mortar!! You’ll be building on the edge. They won’t move.
Got sand in between some of the joints on the oven floor is that a big deal?
Not at all -
If you have an air compressor, just blow the joints before firing your oven for the first time.
If you don’t have a compressor - Just sweep out as much sand as possible and then blast the hearth fire brick joints w/ a can of compressed air (those keyboard duster type cans of air).
Basically - you just want to make sure your pizza isn’t EXTRA crunchy…
