High Temp Mortar for Border Bricks?

Mattone Barile & Mattone Barile Grande Ovens

Hi

My base and block pedestal are complete. Looking ahead in the instructions I see that I should use high temperature mortar for the regular bricks that surround the oven. Since the brick is outside the insulated oven why is high temperature mortar required for them?

Thanks.

Hi Greg,

Good question. The hearth frame bricks are in contact with the firebrick hearth. You COULD get away with regular mortar there, but the heat would eventually degrade the mortar. It’s a judgment call. I chose to go with the high temp mortar to avoid a potential problem 10 years down the line.

Ahh, okay very good point - being in contact. High temperature mortar it is. Thanks!
