A Brick Is A Brick Is A Brick, Right?

When you drive down the street lined with brick houses, do they all look alike? Well, yes and no probably. They are all brick, but they are different colors. 

What you may not realize, though, is that there is a variety of brick types, and they are used for a variety of purposes. 

Here, we are going to take a brief look at the varieties of bricks. First, there are two different classifications of bricks: Unburnt or Burnt. 

Unburnt bricks are also called sun-dried which means as their names say, they are dried in the sun. The burnt bricks are made in molds and baked. Within each of these two categories, there are four classes: 

First class bricked: Table-moulded, standard shape and burnt in kilns. The edges are sharp, smooth, square, and straight and are used for permanent structures built on a superior level of work.

Second class brick: Ground-moulded and burnt in kilns. The surface is rough, and they are irregular in shape. They may have cracks, sharp edges and are used at places where they will be covered in plaster.

Third class bricks: Ground-moulded and baked kilns, they are a soft brick, irregular shape, rough surface and distorted edges. When banged against each other, they have a dull sound and are used in structures that are temporary in areas of the world where the rain is minimal. 

Fourth class bricks: An over-burnt type of brick that has a dark color and irregular shape and is used for concrete in floors, foundations, roads, etc.
