The total proportion of silica should form about 50-60 percent. (It is why the actual clay content and free sand content has to be broadly in the ratio of 4 1 in the good brick earth). Silica is responsible for strength hardness and resistance to shrinkage and shape of the brick and also to a great extent for its durability or long life.
