Fire brick

[brickie in oz]

Most modern house bricks are fired at a much higher temperature that any domestic woodfired oven can ever hope to achieve.

I seriously cant see what all the fuss is about with "fire bricks", its not like you are building a furnace to melt steel or fire ceramics.

I believe firebricks spall less at high temperatures, less grit in your pizza. The question isn't so much whether the brick can survive the high temps once as it is whether the brick can survive dramatic temperature swings (1000F) over and over and over again.

Has anyone on the forum tested this?
Id love to see the data..

It is not the temp they are fired at but their mass and ability to embody with energy (heat) that the brick will release (decay) and cook our food. Non fire bricks don't have the mass aside from spalling etc.

People make fine ovens with other bricks, stones, earth and rocks but a fire brick oven will be stable in heat in/out and if well insulated stay hot for ages.
