In addition, the tolerances for face brick are more exacting to allow the mortar joints to be very uniform. Face brick also tends to have more exacting aesthetic properties with a variety of appearances from additives, firing times, glazes, etc.
Common bricks generally are much more irregularly sized and was typically only be used for the interior wyths of wall construction and concealed work. In recent decades in urban areas it became trendy to expose old common brick walls.

Some facing bricks have one rough or "struck" face to be placed on the outside or "facing" surface; others have a ceramic glaze on one surface. Colours can vary from white or cream to yellow to red or brown or even almost black. Many face bricks are pressed bricks, made with a technique that compresses the clay and forms very smooth faces, sharp edges and perfectly square corners.
