Clay Bricks

Materials

Clays for bricks should be composed of well-blended materials which will produce a good quality product. If lime, which is sometimes added, is not finely ground it will cause "lime blows". This occurs when particles of burnt lime (quicklime) near the surface of the brick expand in contact with rainwater, blowing small and unsightly conical holes in the face of the wall.
