The document classifies bricks according to conventional standards into sundried/katcha bricks and burnt/pacca bricks. Burnt bricks are further classified into four types based on their properties and burning level: first class bricks which are well burnt and uniform; second class bricks which are not as well burnt and uniform; third class or pilla bricks which are under burnt and non-uniform; and overburnt or jhama bricks which are burnt irregularly. Each class of brick has distinct properties and recommended uses.
