Clay engineering bricks are defined as "brick sized fired clay units having a dense and strong semi vitreous body, conforming to defined limits for water absorption and compressive strength.
Stronger and less porous engineering bricks (UK Class A) are usually blue due to the higher firing temperature whilst class B bricks are usually red. Class A bricks have a strength of 125N/mm² and water absorption of less than 4.5%; Class B bricks have a strength greater than 75N/mm² and water absorption of less than 7%.
