Made of same clay(Red or black colour soil from lake side or rive side) as used for Red bricks and they do mix some kerosine to get the sticky kind of material as an out put. They use the machine for mixing including kerosine and passed through moulding machine and when it comes out as a block it will be cut using wired mesh. Size you get mostly 3*6*9 compared to regular bricks which come typically one small thread less like 2.8*5.8*8.7 like this Finishing look will be good for wirecut bricks and they are stronger in nature than regular bricks due to machine processing and kerosine mix which makes mud to hold together stronger.
