  • color of firebricks

    Hopefully someone can help me with the following questions:
    - except the landing area, is it true that the firebricks eventually become black after using it for a while ?
    - Do firebricks with a black color have any performance issue compared to lighter colors ? ( I have read that a light color have a better reflection, but I doubt this is true because I think the light colors eventually become black after using it ..)

    The answer would have to be no.

    Once the oven is cured, a big fire will get it so hot that the soot burns off the inside of the oven - that's how you can tell its the right temperature for pizzas. So the bricks keep their original colour.

      The only persistent soot will be in your entry and around your vent. as Frances says, the dome burns clean with every use.

      I went to great trouble to get "red" firebricks, and after a couple of years of use, the red tint has faded, and you can hardly tell they are different from the beige ones.
