Clay bricks are made from a combination of natural clay bearing soils, minerals and lime.

The indentation in the middle of a pressed clay brick is called a frog.

Clay bricks are either pressed or extruded.

Mortar goes into the frog and core holes.

Mortar goes into the frog and core holes.

Extruded clay bricks are manufactured with holes to lighten the brick, ensuring when fired, they cook evenly. This also allows for improved bond strength and greater earthquake resistance.

Standard brick depth is 70mm up to 110mm in NZ.

A colour through brick is a clay brick that is the same colour through the entire brick body; from face to back.

Standard brick length is 230mm in NZ and varies with trends. Our Corso range by San Selmo features bricks that are 500mm long!

Clay bricks have a front and a back. The front is called the face or stretcher.

Standard brick height in NZ is 76mm. We also supply clay bricks that are 40mm, 50mm, 119 and 162mm in height.

A vitreous coating is when a clay brick has a face colour different to the colour of the brick body. This is achieved by the application of a separate clay coating during the manufacturing process. The vitreous coating is fired in for life.
