Type s or Refractory Mortar
 
Oven has been built and fired about 15 times. Last fire was roaring. I was wanting to put a thin layer of mortar on the outside of the dome to take care of a few areas that leak smoke. Does it matter what type of mortar I use such as a Type S or should I use a refractory mortar?

I'd go with the refactory mortar - it'll get hot on the outside of that dome, once you get the insulation on it!

I concur with Frances...the FB recipe uses more of a type N mortar which would be best for the near vertical surfaces outside the dome...

Thats what i thought. Thanks. Probably will make some following the recipe. Probably will need to do a slow cure of the oven again since the bricks are going to soak up the moisture from the mortar. Tom
