If this rule is not followed, then the brick will crack badly at high temperatures. Sometimes fired clay is replaced by small particles of quartz, coke or graphite, which determines the varieties of fireclay bricks, which differ in their operating temperatures and preferred types of fuel used.

The structure of fireclay bricks is granular, as it is produced by semi-dry molding. Upon impact, fireclay bricks have a ringing sound.
