The compressive strength of bricks produced in the United States ranges from about 7 to 103 MPa (1,000 to 15,000 lbf/in 2), varying according to the use to which the brick are to be put. In England clay bricks can have strengths of up to 100 MPa, although a common house brick is likely to show a range of 20–40 MPa.

[1] Reclaimed London stock bricks are sought after for decorative and conservation use.
The clay there produced bricks of the highest strength and hardness. These bricks were acid resistant, so could be used for the lining of flues and chimneys. There were four brickyards, producing engineering bricks (Enfields, Whinney Hills) and specials. Specials were hand thrown into plaster of Paris moulds. They could be extremely decorative.
The process of a timber structure being repeated in stone is called petrification [23] or petrified carpentry.
