Field test for good quality of burnt clay bricks.

Now let us see the different types of field tests to find out the good quality of burnt clay bricks.

Burnt clay bricks

 1. Shapes and sizes: 

It should have sharp edges with uniform shape and size. The maximum allowance at both ends should be  ±3 mm.

2. Colour test:
