INTRODUCTION

Bricks have been in use since the dawn of civilization. In the initial stages they were used as sun-dried bricks. Burnt bricks have succeeded sun-dried bricks. It has been reported that bricks have been used to build monuments in different parts of the world. Refined brick making and burning techniques have remarkably improved the quality of buildings and other works.

Now, brick plays a prime role in construction at all levels starting from thatched roofs to multi-storeyed buildings. But, the process of brick making has not changed over many years in India except for minor refinements. It is the oldest construction material which has been extensively used at present because of its durability, easy availability and low cost.
